OsMADS57 together with OsTB1 coordinates transcription of its target OsWRKY94 and D14 to switch its organogenesis to defense for cold adaptation in rice.

ABSTRACT: Plants modify their development to adapt to their environment, protecting themselves from detrimental conditions such as chilling stress by triggering a variety of signaling pathways; however, little is known about how plants coordinate developmental patterns and stress responses at the molecular level. Here, we demonstrate that interacting transcription factors OsMADS57 and OsTB1 directly target the defense gene OsWRKY94 and the organogenesis gene D14 to trade off the functions controlling/moderating rice tolerance to cold. Overexpression of OsMADS57 maintains rice tiller growth under chilling stress. OsMADS57 binds directly to the promoter of OsWRKY94, activating its transcription for the cold stress response, while suppressing its activity under normal temperatures. In addition, OsWRKY9
