text: Developing tissues interpret dynamic changes in morphogen activity to generate
cell type diversity. To quantitatively study bone morphogenetic protein (BMP)
signaling dynamics in the mouse neural tube, we developed an embryonic stem cell
differentiation system tailored for growing tissues. Differentiating cells form
striking self-organized patterns of dorsal neural tube cell types driven by sequential
phases of BMP signaling that are observed both in vitro and in vivo. Data-driven
biophysical modeling showed that these dynamics result from coupling fast negative
feedback with slow positive regulation of signaling by the specification of an
endogenous BMP source. Thus, in contrast to relays that propagate morphogen signaling
in space, we identify a BMP signaling relay that operates in time. This mechanism
allows for a rapid initial concentration-sensitive response that is robustly terminated,
thereby regulating balanced sequential cell type generation. Our study provides
an experimental and theoretical framework to understand how signaling dynamics
are exploited in developing tissues.

text: "Crustaceans are a large group of arthropods with a great diversity of species
and\r\ndifferent types of sex determination systems and reproductive modes (Subramoniam,
2017).\r\nThis makes them a great model for exploring the evolution of sex chromosomes
and sexual\r\ndimorphism and investigating the evolutionary mechanisms driving
and maintaining the\r\ndiversity of reproductive systems. Within this taxon, Brine
shrimp of the genus Artemia, a\r\nbranchiopod crustacean, are well suited for
such explorations, as they have both highly\r\ndimorphic traits and closely related
sexual and asexual species. Although brine shrimp are\r\nknown to have ZW sex
chromosomes (Bowen, 1963; Parraguez et al., 2009), the sex\r\nchromosomes are
still not well characterized at the genomic level, the sex-determination gene\r\nis
unknown, and it is still unclear whether the same sex chromosomes as shared by
the\r\ndifferent species.\r\nThe first part of this thesis was to characterize
the Z and W chromosomes in Artemia\r\nusing an array of methods, from generating
multiple chromosome and contig level genome\r\nassemblies to identifying W-linked
scaffolds and transcripts in multiple species using k-mer\r\nbased approaches.\r\nThe
second part tackles the conservation of the cell type specific regulatory pathways\r\nin
the female reproductive system between Artemia and Drosophila, and the expression
of the\r\nZ-specific region throughout meiosis using single-nucleus RNA-seq data.
Our results show\r\nthat germline cells lack dosage compensation, with a subset
of cells showing evidence of\r\nextreme repression of the Z chromosome.\r\nWith
multiple sexual species and several asexual lineages of parthenogenetic females\r\nthat
produce rare males at low frequencies, Brine shrimp present the perfect opportunity
to\r\nexplore the transition to asexuality and shed light on the prerequisites
and repercussions of\r\nthe form of modified meiosis maintaining the asexual lineages.
The last chapter is an\r\ninvestigation of the molecular pathways involved in
asexual reproduction in Artemia using\r\nnewly generated single nucleus RNAseq
and WGS data and previously published data. "

text: "\"Can we do this with a new type of computer - a quantum computer?\". This
famous\r\nquotation of the brilliant Richard Feynman within a conference talk
on \"Simulating physics\r\nwith computers.” is often reverently praised as the
origin of the field of quantum computing.\r\nThe idea was to use quantum mechanical
systems itself to simulate \"Nature\", which is\r\ninherently quantum mechanical.
Now, 43 years later, the theoretical framework of how such\r\na computer can operate
has been developed. Two main important concepts for a potential\r\nquantum supremacy,
superposition and entanglement, have been exploited to design quantum\r\nalgorithms
to significantly speed up certain tasks. Yet, the specific hardware implementation\r\nis
still far from being certain, in fact the race between the most promising platforms
such as\r\nsuperconducting qubits, bosonic codes, cold atoms, trapped ions, optical
computing as well\r\nas spin qubits has recently intensified. If one also includes
the most mature applications of\r\nquantum communication technologies, secure
quantum key distribution and quantum random\r\nnumber generators, as part of a
quantum information technology ecosystem, we are confronted\r\nwith a plethora
of different materials, concepts, and also operation frequencies. While\r\nsuperconducting
qubits, bosonic codes and spin qubits work in the regime of approximately 5\r\nGHz
and are controlled by electrical fields, trapped ions, cold atoms, and optical
quantum\r\ncomputing operate with light in the infrared or visible range.\r\nConsequently,
a quantum frequency converter or microwave-optic transducer is required\r\nto
interface the different frequency domains or establish a long-range network connection\r\nwith
suitable telecom fibers. In fact, the combination of different frequency regimes
is also\r\nan essential part in our classical modern communication network, where
computations are\r\nperformed in electrical circuits and the information exchange
over longer distances happens\r\nvia optical fibers. However, the specific challenges
specific to building a quantum computer,\r\nalso apply to the development of such
a quantum frequency transducer: 1) As we deal with\r\nsingle excitations as the
carrier of information, i.e. the smallest possible quantity, the signal\r\ncan
easily be corrupted by other noise sources which needs to be avoided by all means.
This\r\nis also the reason why microwave quantum computers operate at temperature
environments\r\nclose to zero temperature (< 0.1 Kelvin) to avoid corruption by
thermal noise. 2) The\r\nfrequency interface generally needs to preserve the phase
of the signal as an essential part\r\nof the quantum state. And 3) Quantum signals
cannot be copied which would be a typical\r\nstrategy to account for errors in
classical computers. And finally, there is a challenge specific to\r\nmicrowave-optic
transducers: While quantum computers are operating in one specific frequency\r\ndomain,
microwave-optic transducers combine microwave and optical fields in one device.\r\nThis
results in the particular challenge that high-energy optical radiation, which
is usually\r\nwell-shielded from superconducting microwave quantum processors,
are now an essential part\r\nof the device. The concomitant optical radiation
in the operating transducer will inevitably\r\nhave a detrimental effect on the
superconducting microwave components. Together with the\r\nrequirement of minimal
background noise for quantum-limited operation as described above,\r\nv\r\nheating
from the absorption of optical photons within the same device where single microwave\r\nexcitations
are processed forms a formidable challenge.\r\nThis thesis aims to address this
challenge by developing microwave-optic transducers where\r\nthe impact of optical
absorption on superconducting circuits in general and superconducting\r\nqubits
specifically can be mitigated. In our first approach, we developed a compact device\r\nwith
optimized interaction strengths between the different frequency domains. This
minimizes\r\nthe optical powers used for transducer operation and thus the optical
absorption heating. This\r\nwork was - to the best of our knowledge - the first
comprehensive noise study, in an integrated\r\nmicrowave-optic transducer. Unfortunately,
we saw that the optical absorption heating added\r\nnoise way above a single excitation.
Consequently, a potential quantum signal would have\r\nbeen buried in the noise,
added by the transduction.\r\nBuilding on this insight, we utilized a three-dimensional
microwave-optic transducer instead\r\nof an integrated device. The larger heat
capacity of the macroscopic device with a size\r\nof a few millimeters can absorb
a larger fraction of the optical heating before it increases\r\nthe temperature
of the device. This allowed us to interface the transducer directly with a\r\nsuperconducting
qubit to readout the qubit state in a novel all-optical manner. We showed\r\nthat
the microwave-optic transducer can be operated in a regime in which optical fields
don’t\r\nharm the sensitive qubit. This is an important prerequisite for the operation
of microwave-optic\r\ntransducers in conjunction with microwave quantum processors
and brings the integration and\r\nseamless orchestration of different frequency
components in a quantum network a step closer.\r\n"

text: Recent advancements in superconducting circuits have enabled the experimental
study of collective behavior of precisely controlled intermediate-scale ensembles
of qubits. In this work, we demonstrate an atomic frequency comb formed by individual
artificial atoms strongly coupled to a single resonator mode. We observe periodic
microwave pulses that originate from a single coherent excitation dynamically
interacting with the multiqubit ensemble. We show that this revival dynamics emerges
as a consequence of the constructive and periodic rephasing of the five superconducting
qubits forming the vacuum Rabi split comb. In the future, similar devices could
be used as a memory with in situ tunable storage time or as an on-chip periodic
pulse generator with nonclassical photon statistics.

text: "This thesis explores advancements in quantum remote sensing and non-equilibrium
phase\r\ntransitions in the microwave regime, with a focus on dissipative phase
transitions and quantumenhanced sensing.\r\nIn the first project, I experimentally
studied photon blockade breakdown as a dissipative phase\r\ntransition in a zero-dimensional
cavity-qubit system. By defining an appropriate thermodynamic\r\nlimit, we demonstrated
that the observed bistability is a genuine signature of a first-order\r\nphase
transition in this system. This work provides insight into non-equilibrium quantum\r\ndynamics
and phase transitions in driven-dissipative open quantum systems.\r\nThe second
project focuses on the experimental realization of a phase-conjugate receiver
for\r\nquantum illumination (QI), a quantum sensing protocol that enhances target
detection in noisy\r\nenvironments using entangled light. While an ideal spontaneous
parametric down-conversion\r\n(SPDC) source and receiver could, in theory, provide
up to a 6 dB advantage over classical\r\nillumination, no such ideal receiver
exists. Instead, we explore an experimental realization of a\r\nphase-conjugate
receiver for QI in the microwave regime at millikelvin temperatures using a\r\nJosephson
parametric converter (JPC) as a source of continuous-variable Gaussian entangled\r\nsignal-idler
pairs, where a maximum 3 dB advantage is theoretically achievable. We investigate\r\nkey
experimental limitations that constrain practical QI performance, contributing
to the\r\ndevelopment of quantum-enhanced sensing.\r\nAdditionally, this thesis
presents efficient digital signal processing (DSP) techniques implemented in C++
and Python in collaboration with Przemysław Zieliński and Luka Drmić. These\r\nmethods,
optimized using the Intel Integrated Performance Primitives (IPP) library, have
been\r\nessential in data acquisition, noise filtering, and correlation analysis
across multiple research\r\nprojects. Although not real-time, these DSP techniques
significantly enhance the accuracy of\r\nquantum measurements.\r\nOverall, this
thesis advances quantum-enhanced sensing by establishing the thermodynamic\r\nlimit
in a single transmon-cavity system and experimentally exploring a phase-conjugate
receiver\r\nfor QI. These findings contribute to quantum metrology, particularly
for weak signal detection\r\nand remote sensing in noisy environments.\r\n"

text: "Hole spin qubits are rapidly emerging as the workhorse of semiconducting
quantum processors because of their large spin-orbit interaction, enabling fast
all-electric operations at low power. However, spin-orbit interaction also causes
non-uniformities in devices, resulting in locally varying qubit energies and site-dependent
anisotropies. While these anisotropies can be used to drive single-spins, if not
properly harnessed, they can hinder the path toward large-scale quantum processors.
Here, we report on microwave-driven singlet-triplet qubits in planar germanium
and use them to investigate the anisotropy of two spins in a double quantum dot.
We show two distinct operating regimes depending on the magnetic field direction.
For in-plane fields, the two spins are largely anisotropic, and electrically tunable,
which enables to measure all the available transitions; coherence times exceeding
3 $\\mu$s are extracted. For out-of-plane fields, they have an isotropic response
but preserve the substantial energy difference required to address the singlet-triplet
qubit. Even in this field direction, where the qubit lifetime\r\nis strongly affected
by nuclear spins, we find 400 ns coherence times. Our work adds a valuable tool
to investigate and harness the anisotropy of spin qubits and can be implemented
in any large-scale NxN device, facilitating the path towards scalable quantum
processors."

text: "Over the past century, researchers have been fascinated by the quantum nature
of the\r\nphysical world, initially striving to understand its fundamental principles
and consequences, and\r\neventually progressing toward engineering systems that
can control and manipulate quantum\r\nproperties. Today, we stand at the dawn
of the quantum technology era. While some quantum\r\ntechnologies follow well-defined
roadmaps, others are still in the exciting and uncertain early\r\nstages of development.
In the fields of quantum computing and quantum simulation, research\r\nis being
conducted across a wide variety of platforms. Each of these demonstrates control
over\r\nquantum properties but also faces challenges in scaling up to the level
of a mature technology.\r\nThis thesis explores some of the fundamental properties
of hole spin qubits in planar germanium.\r\nSemiconductor spin qubits are considered
strong candidates for the realization of quantum\r\nprocessors, owing to their
long relaxation and coherence times, as well as their compatibility\r\nwith existing
semiconductor industry infrastructure. Among these, hole spin qubits in planar\r\ngermanium
are particularly promising. Their advantages include a large effective mass, which\r\neases
fabrication constraints; inherent protection from hyperfine noise; and strong
spin-orbit\r\ninteraction, which enables fast and purely electrical control. However,
spin-orbit coupling also\r\nintroduces site-dependent variability across qubits,
particularly in the g-tensors and spin-flip\r\ntunneling, which might cause that
the quantization axes are not aligned. In this thesis, we\r\ninvestigate the tilt
between the quantization axes of two hole spins hosted in a double quantum\r\ndot
as a function of both the magnetic field direction and various electrostatic configurations,\r\ndemonstrating
that both parameters influence this tilt. We conclude by introducing a machine-learning-assisted
routine to automatically tune baseband spin qubits. This approach may prove\r\nto
be a powerful tool for characterizing spin-orbit effects and gaining deeper insight
into the\r\nphysics governing spin qubit behavior.\r\n"

text: In this paper we consider the stochastic primitive equation for geophysical
flows subject to transport noise and turbulent pressure. Admitting very rough
noise terms, the global existence and uniqueness of solutions to this stochastic
partial differential equation are proven using stochastic maximal L² regularity,
the theory of critical spaces for stochastic evolution equations, and global a
priori bounds. Compared to other results in this direction, we do not need any
smallness assumption on the transport noise which acts directly on the velocity
field and we also allow rougher noise terms. The adaptation to Stratonovich type
noise and, more generally, to variable viscosity and/or conductivity are discussed
as well.

text: The Tverberg theorem is one of the cornerstones of discrete geometry. It states
that, given a set X of at least (d+1)(r−1)+1 points in Rd, one can find a partition
X=X1∪⋯∪Xr of X, such that the convex hulls of the Xi, i=1,…,r, all share a common
point. In this paper, we prove a trengthening of this theorem that guarantees
a partition which, in addition to the above, has the property that the boundaries
of full-dimensional convex hulls have pairwise nonempty intersections. Possible
generalizations and algorithmic aspects are also discussed. As a concrete application,
we show that any n points in the plane in general position span ⌊n/3⌋ vertex-disjoint
triangles that are pairwise crossing, meaning that their boundaries have pairwise
nonempty intersections; this number is clearly best possible. A previous result
of Álvarez-Rebollar et al. guarantees ⌊n/6⌋pairwise crossing triangles. Our result
generalizes to a result about simplices in Rd, d≥2.

text: "We consider the spectrum of random Laplacian matrices of the form Ln=An−Dn
where An\r\n is a real symmetric random matrix and Dn is a diagonal matrix whose
entries are equal to the corresponding row sums of An. If An is a Wigner matrix
with entries in the domain of attraction of a Gaussian distribution, the empirical
spectral measure of Ln is known to converge to the free convolution of a semicircle
distribution and a standard real Gaussian distribution. We consider real symmetric
random matrices An with independent entries (up to symmetry) whose row sums converge
to a purely non-Gaussian infinitely divisible distribution, which fall into the
class of Lévy–Khintchine random matrices first introduced by Jung [Trans Am Math
Soc, 370, (2018)]. Our main result shows that the empirical spectral measure of
Ln converges almost surely to a deterministic limit. A key step in the proof
is to use the purely non-Gaussian nature of the row sums to build a random operator
to which Ln converges in an appropriate sense. This operator leads to a recursive
distributional equation uniquely describing the Stieltjes transform of the limiting
empirical spectral measure."

text: We introduce a method to segment the visual field into independently moving
regions, trained with no ground truth or supervision. It consists of an adversarial
conditional encoder-decoder architecture based on Slot Attention, modified to
use the image as context to decode optical flow without attempting to reconstruct
the image itself. In the resulting multi-modal representation, one modality (flow)
feeds the encoder to produce separate latent codes (slots), whereas the other
modality (image) conditions the decoder to generate the first (flow) from the
slots. This design frees the representation from having to encode complex nuisance
variability in the image due to, for instance, illumination and reflectance properties
of the scene. Since customary autoencoding based on minimizing the reconstruction
error does not preclude the entire flow from being encoded into a single slot,
we modify the loss to an adversarial criterion based on Contextual Information
Separation. The resulting min-max optimization fosters the separation of objects
and their assignment to different attention slots, leading to Divided Attention,
or DivA. DivA outperforms recent unsupervised multi-object motion segmentation
methods while tripling run-time speed up to 104FPS and reducing the performance
gap from supervised methods to 12% or less. DivA can handle different numbers
of objects and different image sizes at training and test time, is invariant to
permutation of object labels, and does not require explicit regularization.

text: The phytohormone auxin and its directional transport through tissues play
a fundamental role in development of higher plants. This polar auxin transport
predominantly relies on PIN-FORMED (PIN) auxin exporters. Hence, PIN polarization
is crucial for development, but its evolution during the rise of morphological
complexity in land plants remains unclear. Here, we performed a cross-species
investigation by observing the trafficking and localization of endogenous and
exogenous PINs in two bryophytes, Physcomitrium patens and Marchantia polymorpha,
and in the flowering plant Arabidopsis thaliana. We confirmed that the GFP fusion
did not compromise the auxin export function of all examined PINs by using radioactive
auxin export assay and by observing the phenotypic changes in transgenic bryophytes.
Endogenous PINs polarize to filamentous apices, while exogenous Arabidopsis PINs
distribute symmetrically on the membrane in both bryophytes. In Arabidopsis root
epidermis, bryophytic PINs show no defined polarity. Pharmacological interference
revealed a strong cytoskeleton dependence of bryophytic but not Arabidopsis PIN
polarization. The divergence of PIN polarization and trafficking is also observed
within the bryophyte clade and between tissues of individual species. These results
collectively reveal a divergence of PIN trafficking and polarity mechanisms throughout
land plant evolution and a co-evolution of PIN sequence-based and cell-based polarity
mechanisms.

text: For a locally finite set in R2, the order-k Brillouin tessellations form an
infinite sequence of convex face-to-face tilings of the plane. If the set is coarsely
dense and generic, then the corresponding infinite sequences of minimum and maximum
angles are both monotonic in k. As an example, a stationary Poisson point process
in R2 is locally finite, coarsely dense, and generic with probability one. For
such a set, the distributions of angles in the Voronoi tessellations, Delaunay
mosaics, and Brillouin tessellations are independent of the order and can be derived
from the formula for angles in order-1 Delaunay mosaics given by Miles (Math.
Biosci. 6, 85–127 (1970)).

text: "We consider the problem of computing the maximal probability of satisfying
an \r\n-regular specification for stochastic, continuous-state, nonlinear systems
evolving in discrete time. The problem reduces, after automata-theoretic constructions,
to finding the maximal probability of satisfying a parity condition on a (possibly
hybrid) state space. While characterizing the exact satisfaction probability is
open, we show that a lower bound on this probability can be obtained by (I) computing
an under-approximation of the qualitative winning region, i.e., states from which
the parity condition can be enforced almost surely, and (II) computing the maximal
probability of reaching this qualitative winning region.\r\nThe heart of our approach
is a technique to symbolically compute the under-approximation of the qualitative
winning region in step (I) via a finite-state abstraction of the original system
as a \r\n-player parity game. Our abstraction procedure uses only the support
of the probabilistic evolution; it does not use precise numerical transition probabilities.
We prove that the winning set in the abstract -player game induces an under-approximation
of the qualitative winning region in the original synthesis problem, along with
a policy to solve it. By combining these contributions with (a) a symbolic fixpoint
algorithm to solve \r\n-player games and (b) existing techniques for reachability
policy synthesis in stochastic nonlinear systems, we get an abstraction-based
algorithm for finding a lower bound on the maximal satisfaction probability.\r\nWe
have implemented the abstraction-based algorithm in Mascot-SDS, where we combined
the outlined abstraction step with our tool Genie (Majumdar et al., 2023) that
solves \r\n-player parity games (through a reduction to Rabin games) more efficiently
than existing algorithms. We evaluated our implementation on the nonlinear model
of a perturbed bistable switch from the literature. We show empirically that the
lower bound on the winning region computed by our approach is precise, by comparing
against an over-approximation of the qualitative winning region. Moreover, our
implementation outperforms a recently proposed tool for solving this problem by
a large margin."
acknowledgement: "We thank Daniel Hausmann and Nir Piterman for their valuable comments
on an earlier version of the manuscript of our other paper [22] where we present,
among other things, the parity fixpoint for 2 1/2-player games (for a slightly more
general class of games) with a different and indirect proof of correctness. Based
on their comments we observed that, unlike the other fixpoints that we present in
[22], the parity fixpoint does not follow the exact same structure as its counterpart
for 2-player games, which we also use int his paper.\r\nWe also thank Thejaswini
Raghavan for observing that our symbolic parity fixpoint algorithm can be solved
in quasi-polynomial time using recent improved algorithms for solving \r\n-calculus
expressions. This significantly improved the complexity bounds of our algorithm
in this paper.\r\nThe work of R. Majumdar and A.-K. Schmuck are partially supported

text: Low‐cost, safe, and environmental‐friendly rechargeable aqueous zinc‐ion batteries
(ZIBs) are promising as next‐generation energy storage devices for wearable electronics
among other applications. However, sluggish ionic transport kinetics and the unstable
electrode structure during ionic insertion/extraction hampers their deployment.
Herein, we propose a new cathode material based on a layered metal chalcogenide
(LMC), bismuth telluride (Bi2Te3), coated
with polypyrrole (PPy). Taking advantage of the PPy coating, the Bi2Te3@PPy
composite presents strong ionic absorption affinity, high oxidation resistance,
and high structural stability. The ZIBs based on Bi2Te3@PPy
cathodes exhibit high capacities and ultra‐long lifespans of over 5000 cycles.
They also present outstanding stability even under bending. In addition, we analyze
here the reaction mechanism using in situ X‐ray diffraction, X‐ray photoelectron
spectroscopy, and computational tools and demonstrate that, in the aqueous system,
Zn2+ is not inserted into the cathode as previously assumed.
In contrast, proton charge storage dominates the process. Overall, this work not
only shows the great potential of LMCs as ZIBs cathode materials and the advantages
of PPy coating, but also clarifies the charge/discharge mechanism in rechargeable
ZIBs based on LMCs.

text: "Auxin belongs among major phytohormones and governs multiple aspects of plant
growth and development. The establishment of auxin concentration gradients, determines,
among other processes, plant organ positioning and growth responses to environmental
stimuli.\r\nHerein we report the synthesis of new NBD- or DNS-labelled IAA derivatives
and the elucidation of their biological activity, fluorescence properties and
subcellular accumulation patterns in planta. These novel compounds did not show
auxin-like activity, but instead antagonized physiological auxin effects. The
DNS-labelled derivatives FL5 and FL6 showed strong anti-auxin activity in roots
and hypocotyls, which also occurred at the level of gene transcription as confirmed
by quantitative PCR analysis. The auxin antagonism of our derivatives was further
demonstrated in vitro using an SPR-based binding assay. The NBD-labelled compound
FL4 with the best fluorescence properties proved to be unsuitable to study auxin
accumulation patterns in planta. On the other hand, the strongest anti-auxin activity
possessing compounds FL5 and FL6 could be useful to study binding mechanisms to
auxin receptors and for manipulations of auxin-regulated processes."

text: 'We investigate the potential of Multi-Objective, Deep Reinforcement Learning
for stock and cryptocurrency single-asset trading: in particular, we consider
a Multi-Objective algorithm which generalizes the reward functions and discount
factor (i.e., these components are not specified a priori, but incorporated in
the learning process). Firstly, using several important assets (BTCUSD, ETHUSDT,
XRPUSDT, AAPL, SPY, NIFTY50), we verify the reward generalization property of
the proposed Multi-Objective algorithm, and provide preliminary statistical evidence
showing increased predictive stability over the corresponding Single-Objective
strategy. Secondly, we show that the Multi-Objective algorithm has a clear edge
over the corresponding Single-Objective strategy when the reward mechanism is
sparse (i.e., when non-null feedback is infrequent over time). Finally, we discuss
the generalization properties with respect to the discount factor. The entirety

text: Inversions are thought to play a key role in adaptation and speciation, suppressing
recombination between diverging populations. Genes influencing adaptive traits
cluster in inversions, and changes in inversion frequencies are associated with
environmental differences. However, in many organisms, it is unclear if inversions
are geographically and taxonomically widespread. The intertidal snail, Littorina
saxatilis, is one such example. Strong associations between putative polymorphic
inversions and phenotypic differences have been demonstrated between two ecotypes
of L. saxatilis in Sweden and inferred elsewhere, but no direct evidence for inversion
polymorphism currently exists across the species range. Using whole genome data
from 107 snails, most inversion polymorphisms were found to be widespread across
the species range. The frequencies of some inversion arrangements were significantly
different among ecotypes, suggesting a parallel adaptive role. Many inversions
were also polymorphic in the sister species, L. arcana, hinting at an ancient
origin.

text: Entire chromosomes are typically only transmitted vertically from one generation
to the next. The horizontal transfer of such chromosomes has long been considered
improbable, yet gained recent support in several pathogenic fungi where it may
affect the fitness or host specificity. To date, it is unknown how these transfers
occur, how common they are and whether they can occur between different species.
In this study, we show multiple independent instances of horizontal transfers
of the same accessory chromosome between two distinct strains of the asexual entomopathogenic
fungusMetarhizium robertsiiduring experimental co-infection
of its insect host, the Argentine ant. Notably, only the one chromosome – but
no other – was transferred from the donor to the recipient strain. The recipient
strain, now harboring the accessory chromosome, exhibited a competitive advantage
under certain host conditions. By phylogenetic analysis we further demonstrate
that the same accessory chromosome was horizontally transferred in a natural environment
betweenM. robertsiiand another congeneric insect pathogen,M.
guizhouense. Hence horizontal chromosome transfer is not limited
to the observed frequent events within species during experimental infections
but also occurs naturally across species. The transferred accessory chromosome
contains genes that might be involved in its preferential horizontal transfer,
encoding putative histones and histone-modifying enzymes, but also putative virulence
factors that may support its establishment. Our study reveals that both intra-
and interspecies horizontal transfer of entire chromosomes is more frequent than
previously assumed, likely representing a not uncommon mechanism for gene exchange.Significance
StatementThe enormous success of bacterial pathogens has
been attributed to their ability to exchange genetic material between one another.
Similarly, in eukaryotes, horizontal transfer of genetic material allowed the
spread of virulence factors across species. The horizontal transfer of whole chromosomes
could be an important pathway for such exchange of genetic material, but little
is known about the origin of transferable chromosomes and how frequently they
are exchanged. Here, we show that the transfer of accessory chromosomes - chromosomes
that are non-essential but may provide fitness benefits - is common during fungal
co-infections and is even possible between distant pathogenic species, highlighting
the importance of horizontal gene transfer via chromosome transfer also for the
evolution and function of eukaryotic pathogens.
