AtHUB2 significantly enhances the drought tolerance of transgenic cotton in the greenhouse. (a) Drought tolerance of control plants and AtHUB2‐expressing cotton plants. Photographs were taken at 4 weeks after germination, after 20, 28 and 35 days of drought stress, and after a 1‐week recovery period. Bar = 7.5 cm. (b) Leaf relative water content (RWC), proline content and soluble sugar content of transgenic cotton and control plants with or without drought treatment (n ≥ 30). (c) Survival rates of plants after 1 week of recovery (n ≥ 30). Vertical bars represent SD. (*P < 0.05; **P < 0.01).
