Effects of H2S on mitochondrial ultrastructure in WT, des1 and OE-DES1 plants at different developmental stages under drought-stress conditions. The 1-, 3-, 5-, and 7-week-old seedlings were subjected to drought stress by withholding water for 7 days, and then samples of leaves were collected. Ultrastructure of WT (A,D,G,J), des1 (B,E,H,K), and OE-DES1 (C,F,I,L) were observed using TEM. Bars = 0.2 μm. M, mitochondrion; C, chloroplast. The tubular shape or remnants of cristae were labeled by arrows.
