Fig. 6From: AgMYB5, an MYB transcription factor from celery, enhanced β-carotene synthesis and promoted drought tolerance in transgenic ArabidopsisDrought tolerance of WT and transgenic Arabidopsis lines planted in soil. A The water loss rate (percent water loss per hour) and (B) the survival rate of WT and transgenic lines (OE1 and OE4). C The extent of stomatal closure and (D) stomata aperture of WT and transgenic lines under normal and drought conditions. The asterisk indicates a statistically significant difference (*, P < 0.05; **, P < 0.01)Back to article page
