Ectopic expression of safflower NAC transcription factor <i>CtNAC78</i> enhances drought tolerance in <i>Arabidopsis thaliana</i>.

ABSTRACT: Drought has become a key abiotic stress factor that seriously affects crop yield, including that of safflower, an important crop grown worldwide. Our previous work showed that drought stress markedly upregulated CtNAC78 expression in safflower. Hence, to investigate CtNAC78's function in drought tolerance, transgenic Arabidopsis thaliana with ectopic expression of CtNAC78 was treated with drought in the present work. It was shown that the transgenic A. thaliana exhibited better growth status, higher antioxidant enzyme activity, greater accumulation of chlorophyll and osmolytes, and lower levels of MDA and H₂O₂, indicating that ectopic expression of CtNAC78 enhanced drought tolerance of A. thaliana. Furthermore, a yeast
