Phenotypes of GLA 4 as well as osftl4-1 and osftl4-2 mutants under drought conditions. a–c Both mutants (osftl4-1 and osftl4-2) exhibited enhanced drought tolerance. The GLA 4, osftl4-1, and osftl4-2 seedlings (nearly 40 seedlings per genotype) with regular watering for 14 days a were subjected to drought stress for 4 days b, and recovery for 7 days c, respectively. Scale bars, 5 cm. d Survival rate calculated on the basis of the growth of a new leaf blade after 7 days of re-watering. Error bars represent the SE of three biological replicates (**, p < 0.01, by Student’s t-test). e Water loss rate of detached leaves from the wild-type and mutant lines at different time-points. Data are presented as the mean ± standard deviation (n = 20). f Stomatal conductance of the wild-type and two mutant lines under normal and drought stress conditions. Error bars represent three biological replicates (six plants per replicate). g OsNCED4, OsbZIP23, and Rab16c expression levels in wild-type and osftl4 plants under normal and drought conditions. Mean values ± SD were obtained from three technical repeats and three biological repeats. Statistical differences are labeled with different letters using LSD test (p < 0.05, one-way ANOVA)
