<i>OsNAC15</i> regulates drought and salt tolerance in rice.

ABSTRACT: The NAC (NAM, ATAF1/2 and CUC2) transcription factors (TFs) play important roles in rice abiotic stress tolerance. OsNAC15 has been reported to regulate zinc deficiency and cadmium tolerance. However, the roles of OsNAC15 in rice drought and salt tolerance are largely unknown. In this study, we characterized a nuclear-localized NAC TF in rice, OsNAC15, that positively regulates drought and salt tolerance and directly participates in the biosynthesis of abscisic acid (ABA). Drought and salt treatment significantly induce the expression of OsNAC15. Loss of OsNAC15 could made plants more sensitive to drought and salt stress and led to the accumulation of more H₂O₂ and malondialdehyde (MDA) in vivo after drought and salt stress, while ov
