  • 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
