text	OsNAC3 TF positively regulates ABA response and salt tolerance in rice (Zhang et al., 2021). OsNAC3 is nuclear localized TF(experimental evidence; Zhang et al., 2021). Under normal growth conditions, OsNAC3 is predominantly expressed in the leaf sheath and shows the lowest expression in the stem and leaf. However, ABA and NaCl treatment induced OsNAC3 expression in roots. OsNAC3 knockout rice plants show decreased sensitivity to ABA but increased sensitivity to salt stress, while OsNAC3 overexpression showed the opposite effect. Loss of OsNAC3 induces Na+ accumulation in the shoots. OsNAC3 regulates ABA response and salt tolerance genes, such as OsHKT1;4, OsHKT1;5, OsLEA3?1, OsPM-1, OsPP2C68, and OsRAB-21. OsNAC is upregulated in OsDRAP1 overexpression lines, and its promoter has a binding site for OsDRAP1 (Wang et al., 2021).
