Fig. 3From: Overexpression of OsNAR2.1 by OsNAR2.1 promoter increases drought resistance by increasing the expression of OsPLDα1 in riceGrowth parameters under limited water supply conditions. Phenotype of transgenic lines grown in (A) full watering (100% field capacity, Control) and (B) limited water supply conditions (60% field capacity, Drought) at anthesis stage. (C) Chlorophyll content, (D) relative water content, (E) photosynthesis rate and (F) water use efficiency were assayed. Error bars: SE (n = 5). The different letters indicate a significant difference between the transgenic line and the WT (P < 0.05, one-way ANOVA, least significance difference model)Back to article page
