- Key message
- OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice.
- OsbZIP42 is a positive regulator of ABA signaling and drought stress tolerance
- The expression of OsbZIP42 was induced by ABA treatment, although it was not induced by drought and salt stresses
- These results suggest that OsbZIP42 is a positive regulator of ABA signaling and drought stress tolerance depending on its activation, which is followed by an additional ABA-dependent modification
- We propose that OsbZIP42 is an important player in rice for conferring ABA-dependent drought tolerance
- Transgenic rice overexpressing OsbZIP42 (OsbZIP42-OX) exhibited a rapidly elevated expression of the ABA-responsive LEA3 and Rab16 genes and was hypersensitive to ABA
- The activation of OsbZIP42 depends on stress-/ABA-activated protein kinase 4 (SAPK4) and an additional ABA-dependent modification of OsbZIP42
- Connection
- OsbZIP42~HBF1, SAPK4~OSPDK, OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice., The activation of OsbZIP42 depends on stress-/ABA-activated protein kinase 4 (SAPK4) and an additional ABA-dependent modification of OsbZIP42
- OsbZIP42~HBF1, SAPK4~OSPDK, OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice., Although the full-length OsbZIP42 protein did not, the N-terminus of the protein interacted with SAPK4
- OsbZIP42~HBF1, SAPK4~OSPDK, OsbZIP42 is a positive regulator of ABA signaling and confers drought tolerance to rice., Our results suggest that the activation of OsbZIP42 by SAPK4 requires another ABA-dependent modification of OsbZIP42
- OsbZIP42~HBF1, Hd3a, Antagonistic Transcription Factor Complexes Modulate the Floral Transition in Rice., However, additional bZIPs, including Hd3a BINDING REPRESSOR FACTOR 1 (HBF1) and HBF2 form repressor complexes that reduce Hd3a and RFT1 expression to delay flowering
- OsbZIP42~HBF1, OsGI-Hd1-Hd3a~RFT1, Antagonistic Transcription Factor Complexes Modulate the Floral Transition in Rice., However, additional bZIPs, including Hd3a BINDING REPRESSOR FACTOR 1 (HBF1) and HBF2 form repressor complexes that reduce Hd3a and RFT1 expression to delay flowering
