Fig. 5

Evaluating drought stress tolerance of SAPK9 overexpressed (OE) and gene silenced (RNAi) transgenic rice plants. a-i Pictures showing three sets of plants, i.e. OE, RNAi and NT in the vegetative stage under the conditions of before drought stress, after drought stress and subsequent recovery after drought stress. a-ii Survival rates (%) of OE, RNAi, and NT plants in the vegetative stage. b-i Pictures showing OE, RNAi, and NT plants in early reproductive (panicle initiation) stage under the conditions of before drought stress, after drought stress and subsequent recovery after drought stress. b-ii Survival rates (%) of OE, RNAi and NT plants in the early reproductive stage. c-i Comparison of water loss rate (WLR) and (c-ii) relative water content (RWC) of the detached leaves from transgenic lines and NT plants at the five-leaf stage. Estimation of the contents of (d-i) proline and (d-ii) soluble sugar in leaf tissues of transgenic lines and NT plants before and after drought stress
