  text: In order to establish a reference for analysis of the function of auxin and
    the auxin biosynthesis regulators SHORT INTERNODE/ STYLISH (SHI/STY) during Physcomitrella
    patens reproductive development, we have described male (antheridial) and female
    (archegonial) development in detail, including temporal and positional information
    of organ initiation. This has allowed us to define discrete stages of organ morphogenesis
    and to show that reproductive organ development in P. patens is highly organized
    and that organ phyllotaxis differs between vegetative and reproductive development.
    Using the PpSHI1 and PpSHI2 reporter and knockout lines, the auxin reporters GmGH3pro:GUS
    and PpPINApro:GFP-GUS, and the auxin-conjugating transgene PpSHI2pro:IAAL, we
    could show that the PpSHI genes, and by inference also auxin, play important roles
    for reproductive organ development in moss. The PpSHI genes are required for the
    apical opening of the reproductive organs, the final differentiation of the egg
    cell, and the progression of canal cells into a cell death program. The apical
    cells of the archegonium, the canal cells, and the egg cell are also sites of
    auxin responsiveness and are affected by reduced levels of active auxin, suggesting
    that auxin mediates PpSHI function in the reproductive organs.
