This study examines the effects of auxin antagonist PEO-IAA and transport inhibitor NPA on gametophore development in Physcomitrium patens, finding that auxin sensing and transport are critical for specific developmental processes but not for bud-to-leafy-shoot transition.

This study defines sporopollenin (SP) as specific to embryophytes by showing all five polyketide pathway enzymes are present in embryophytes but absent in green algae.

This paper describes the morphogenetic patterns of protonemata and gametophores in Physcomitrium patens, focusing on the directional growth and branching of chloronemata and caulonemata.
