35S:GmNFYA13 Arabidopsis seedlings showed enhanced drought tolerance compared to WT lines at the seedling stage. (A) Evaluation of drought tolerance in WT and 35S:GmNFYA13 transgenic Arabidopsis plants. Three-week-old seedlings were subjected to drought treatment for 9 days and recovered for 7 days. (B) The SWP of the soil where WT and 35S:GmNFYA13 were grown. (C) The water loss of detached leaves from WT and 35S:GmNFYA13 Arabidopsis seedlings. (D) The survival rate of WT and 35S:GmNFYA13 Arabidopsis seedlings after recovery from drought treatment. (E,F) The relative water content and proline content of WT and 35S:GmNFYA13 Arabidopsis seedlings after drought treatment. (G) The ABA concentration of WT and 35S:GmNFYA13 Arabidopsis seedlings following drought treatment for 4 days. (H–K) Transcript levels of DREB2A, ABI3, NCED3, and RD29A under control and drought treatment. Transcript levels of these genes were normalized to those in WT plants under control conditions, AtTub8 was used as the internal control. Data indicate three biological replicates ± SD. Different letters above the columns represent significant differences at P < 0.05. Three biological replicates were used in each experiment.
