- MSU: LOC_Os04g44500
- RAPdb: Os04g0526800
- Publication
- OsABAR1, a novel GRAM domain-containing protein, confers drought and salt tolerance via an ABA-dependent pathway in rice., 2020, Plant Physiol Biochem..

Genbank accession number
- Key message
- Furthermore, OsABAR1-OX seedlings were hypersensitive to exogenous ABA, whereas Osabar1 seedlings were hyposensitive
- Moreover, OsABAR1 expression was up-regulated by drought and salinity stresses
- These results imply that OsABAR1 is a positive regulator of the ABA pathway and confirm that OsABAR1 improves rice drought and salt tolerance via an ABA-dependent pathway
- In turn, OsABAR1 regulated the expression of ABA metabolic genes and responsive genes
- The OsABAR1 protein was localized in the cytoplasm and nucleus
- We further analyzed the involvement of OsABAR1 in the abscisic acid (ABA) signaling pathway
- The OsABAR1 expression level was up-regulated by ABA
- Connection
- OsABAR1, STK, Receptor-Like Cytoplasmic Kinase STK Confers Salt Tolerance in Rice., Reverse transcription quantitative PCR (RT-qPCR) suggested that four stress-related genes may be regulated by STK including OsABAR1, Os3BGlu6, OSBZ8 and OsSIK1
