Over-expression of CaNAC46 in Arabidopsis improves salt and drought stress tolerance. A The seedlings of transgenic and WT plants were cultured with containing 1/2 MS, 1/2 MS with 200 mM NaCl and 1/2 MS with 10% PEG6000 agar medium for 7 days. B Performance of 3-week-old WT, CaNAC46-OE1 and OE1 plants grown under drought stress for 3 weeks and were re-watered for 3 days (upper); 3-week-old WT, CaNAC46-OE1 and OE1 plants were watered 200 mM NaCl for 3 weeks (below). C The number and length of roots were counted at 1-week-old seedling stage. Three independent biological experiments were performed. Superscript letters indicate significant differences (P < 0.05)
