text: "Females and males across species are subject to divergent selective pressures
arising\r\nfrom di↵erent reproductive interests and ecological niches. This often
translates into a\r\nintricate array of sex-specific natural and sexual selection
on traits that have a shared\r\ngenetic basis between both sexes, causing a genetic
sexual conflict. The resolution of\r\nthis conflict mostly relies on the evolution
of sex-specific expression of the shared genes,\r\nleading to phenotypic sexual
dimorphism. Such sex-specific gene expression is thought\r\nto evolve via modifications
of the genetic networks ultimately linked to sex-determining\r\ntranscription
factors. Although much empirical and theoretical evidence supports this\r\nstandard
picture of the molecular basis of sexual conflict resolution, there still are
a\r\nfew open questions regarding the complex array of selective forces driving
phenotypic\r\ndi↵erentiation between the sexes, as well as the molecular mechanisms
underlying sexspecific adaptation. I address some of these open questions in my
PhD thesis.\r\nFirst, how do patterns of phenotypic sexual dimorphism vary within
populations,\r\nas a response to the temporal and spatial changes in sex-specific
selective forces? To\r\ntackle this question, I analyze the patterns of sex-specific
phenotypic variation along\r\nthree life stages and across populations spanning
the whole geographical range of Rumex\r\nhastatulus, a wind-pollinated angiosperm,
in the first Chapter of the thesis.\r\nSecond, how do gene expression patterns
lead to phenotypic dimorphism, and what\r\nare the molecular mechanisms underlying
the observed transcriptomic variation? I\r\naddress this question by examining
the sex- and tissue-specific expression variation in\r\nnewly-generated datasets
of sex-specific expression in heads and gonads of Drosophila\r\nmelanogaster.
I additionally used two complementary approaches for the study of the\r\ngenetic
basis of sex di↵erences in gene expression in the second and third Chapters of\r\nthe
thesis.\r\nThird, how does intersex correlation, thought to be one of the main
aspects constraining the ability for the two sexes to decouple, interact with
the evolution of sexual\r\ndimorphism? I develop models of sex-specific stabilizing
selection, mutation and drift\r\nto formalize common intuition regarding the patterns
of covariation between intersex\r\ncorrelation and sexual dimorphism in the fourth
Chapter of the thesis.\r\nAlltogether, the work described in this PhD thesis provides
useful insights into the\r\nlinks between genetic, transcriptomic and phenotypic
layers of sex-specific variation,\r\nand contributes to our general understanding
of the dynamics of sexual dimorphism\r\nevolution."

text: "The regulatory architecture of gene expression is known to differ substantially
between sexes in Drosophila, but most studies performed\r\nso far used whole-body
data and only single crosses, which may have limited their scope to detect patterns
that are robust across tissues\r\nand biological replicates. Here, we use allele-specific
gene expression of parental and reciprocal hybrid crosses between 6 Drosophila\r\nmelanogaster
inbred lines to quantify cis- and trans-regulatory variation in heads and gonads
of both sexes separately across 3 replicate\r\ncrosses. Our results suggest that
female and male heads, as well as ovaries, have a similar regulatory architecture.
On the other hand,\r\ntestes display more and substantially different cis-regulatory
effects, suggesting that sex differences in the regulatory architecture that\r\nhave
been previously observed may largely derive from testis-specific effects. We also
examine the difference in cis-regulatory variation\r\nof genes across different
levels of sex bias in gonads and heads. Consistent with the idea that intersex
correlations constrain expression\r\nand can lead to sexual antagonism, we find
more cis variation in unbiased and moderately biased genes in heads. In ovaries,
reduced cis\r\nvariation is observed for male-biased genes, suggesting that cis
variants acting on these genes in males do not lead to changes in ovary\r\nexpression.
Finally, we examine the dominance patterns of gene expression and find that sex-
and tissue-specific patterns of inheritance\r\nas well as trans-regulatory variation
are highly variable across biological crosses, although these were performed in
highly controlled\r\nexperimental conditions. This highlights the importance of
using various genetic backgrounds to infer generalizable patterns."

text: "* Understanding the mechanisms causing phenotypic differences between females
and males has long fascinated evolutionary biologists. An extensive literature
exists on animal sexual dimorphism but less information is known about sex differences
in plants, particularly the extent of geographical variation in sexual dimorphism
and its life‐cycle dynamics.\r\n* Here, we investigated patterns of genetically
based sexual dimorphism in vegetative and reproductive traits of a wind‐pollinated
dioecious plant, Rumex hastatulus, across three life‐cycle stages using open‐pollinated
families from 30 populations spanning the geographic range and chromosomal variation
(XY and XY1Y2) of the species.\r\n* The direction and degree of sexual dimorphism
was highly variable among populations and life‐cycle stages. Sex‐specific differences
in reproductive function explained a significant amount of temporal change in
sexual dimorphism. For several traits, geographical variation in sexual dimorphism
was associated with bioclimatic parameters, likely due to the differential responses
of the sexes to climate. We found no systematic differences in sexual dimorphism
between chromosome races.\r\n* Sex‐specific trait differences in dioecious plants
largely result from a balance between sexual and natural selection on resource
allocation. Our results indicate that abiotic factors associated with geographical
context also play a role in modifying sexual dimorphism during the plant life‐cycle."

text: Understanding the mechanisms causing phenotypic differences between females
and males has long fascinated evolutionary biologists. An extensive literature
exists on animal sexual dimorphism but less is known about sex differences in
plants, particularly the extent of geographical variation in sexual dimorphism
and its life-cycle dynamics. Here, we investigate patterns of genetically-based
sexual dimorphism in vegetative and reproductive traits of a wind-pollinated dioecious
plant, Rumex hastatulus, across three life-cycle stages using open-pollinated
families from 30 populations spanning the geographic range and chromosomal variation
(XY and XY1Y2) of the species. The direction and degree of sexual dimorphism was
highly variable among populations and life-cycle stages. Sex-specific differences
in reproductive function explained a significant amount of temporal change in
sexual dimorphism. For several traits, geographical variation in sexual dimorphism
was associated with bioclimatic parameters, likely due to the differential responses
of the sexes to climate. We found no systematic differences in sexual dimorphism
between chromosome races. Sex-specific trait differences in dioecious plants largely
result from a balance between sexual and natural selection on resource allocation.
Our results indicate that abiotic factors associated with geographical context
also play a role in modifying sexual dimorphism during the plant life cycle.

text: Pleiotropy is the well-established idea that a single mutation affects multiple
phenotypes. If a mutation has opposite effects on fitness when expressed in different
contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce
the efficacy of selection by limiting the fixation of beneficial mutations through
adaptation, and the removal of deleterious mutations through purifying selection.
Although this has been widely discussed, in particular in the context of a putative
“gender load,” it has yet to be systematically quantified. In this work, we empirically
estimate to which extent different pleiotropic regimes impede the efficacy of
selection in Drosophila melanogaster. We use whole-genome polymorphism data from
a single African population and divergence data from D. simulans to estimate the
fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction
of selection (DoS). After controlling for confounding covariates, we find that
the different pleiotropic regimes have a relatively small, but significant, effect
on selection efficacy. Specifically, our results suggest that pleiotropic sexual
antagonism may restrict the efficacy of selection, but that this conflict can
be resolved by limiting the expression of genes to the sex where they are beneficial.
Intermediate levels of pleiotropy across tissues and life stages can also lead
to maladaptation in D. melanogaster, due to inefficient purifying selection combined
with low frequency of mutations that confer a selective advantage. Thus, our study
highlights the need to consider the efficacy of selection in the context of antagonistic
pleiotropy, and of genetic conflict in general.
