  bibo_abstract:
  - Auxin, primarily indole-3-acetic acid (IAA), is a central regulator of growth
    and development in land plants, but its physiological role in chlorophyte algae
    remains unclear. Here, we show that exogenous IAA modulates growth in Chlorella
    sorokiniana, Chlorella variabilis, and Chlamydomonas reinhardtii in a concentration-dependent
    manner. Low IAA concentrations promoted growth by accelerating the onset of cell
    division without affecting cell size, whereas higher concentrations inhibited
    proliferation. Radiotracer assays showed that all three species take up and release
    IAA across the plasma membrane through a combination of passive diffusion and
    energy-dependent, saturable processes. Competition by excess unlabeled natural
    and synthetic auxins further supported the presence of carrier-mediated transport
    with broad substrate recognition. Phylogenetic analyses identified potential PIN-like
    auxin exporters in chlorophytes and other non-plant eukaryotes, and structural
    modeling supported conservation of the overall PIN fold and predicted auxin-binding
    residues. However, functional assays in Xenopus laevis oocytes, tobacco BY-2 cultured
    cells, and Arabidopsis thaliana did not support a role for these proteins in directional
    auxin export. Instead, non-plant PIN homologs localized predominantly to the endoplasmic
    reticulum and showed limited or no transport activity in heterologous systems.
    Together, these findings indicate that auxin responsiveness and basic cellular
    auxin transport predate canonical PIN-mediated directional auxin export, which
    appears to be a later innovation of the streptophyte lineage.@eng
