WD40–1 enhances drought tolerance in alfalfa. a above ground phenotypes of WT, four WD40–1RNAi and four WD40–1OE genotypes during drought stress; b transcript levels of WD40–1 in WT, WD40–1RNAi WD40–1OE genotypes used for the study; c leaf water potential in WT and WD40–1OE genotypes under well-watered and drought stress condition; d root weight in drought stressed WT, WD40–1RNAi and WD40–1OE plants; e root length in well-watered and drought stressed WT, WD40–1RNAi and WD40–1OE plants; and f chlorophyll concentration in well-watered and drought stressed WT, WD40–1RNAi and WD40–1OE plants. Values are means ± SE; n = 4 individual plants for ‘b’ to ‘e’ while n = 20 in ‘f’. ANOVA p values are provided in Additional file 2: Table S5.3. Significant difference in Post hoc Tukey multiple comparisons test is indicated with different letters
