Seed germination, root length and phenotypes of WT and overexpression RcNAC72 lines under drought treatment. (A). Seed germination of WT and overexpression RcNAC72 lines with different concentrations of mannitol. (B). Germination rate in MS medium. (C). Germination rate in MS medium with 100 mM mannitol. (D). Germination rate in MS medium with 200 mM mannitol. (E). Germination rate in MS medium with 300 mM mannitol. (F). Germination rate in MS medium with 400 mM mannitol. (G). Statistics of germination rate under mannitol treatment. (H). Seed root length of WT and overexpression RcNAC72 lines with different concentrations of mannitol. (I). Root length statistics under mannitol treatment. (J). Performance of WT and RcNAC72 transgenic lines after drought treatment. (K). Soluble sugar content in WT and RcNAC72 transgenic lines after drought treatment. (L). MDA content in WT and RcNAC72 transgenic lines after drought treatment. Three biological replications were performed. The bars show the SD. Asterisks indicate a significant difference ** p < 0.01 and * p < 0.5 compared with the corresponding controls.
