Here we show that in the moss P. patens exogenous application of the phytohormone ABA triggers the formation of vegetative diaspores (brachycytes or brood cells) that enable plant survival in unfavorable environmental conditions. Almost all members of ABA-dependent signaling and regulation were transcriptionally induced. Network analysis of transcription-associated genes revealed a large overlap with ABA-dependent regulation in response to dehydration, cold stress, and UV-B light, indicating a fundamental function in stress response.
