Detection of ABA sensitivity in transgenic plants overexpressing StPYL20. Transgenic tobacco stem segments exhibiting consistent growth were cultured on 1/2MS medium alone or supplemented with 20 µM ABA to induce stress, following which various phenotypic characteristics were evaluated. (a) Phenotypic profiling of plants under control and stress conditions; (b) quantification of plant height, number of green leaves, and fresh weight under both control and drought stress conditions. Mean values from three independent biological replicates, each with 9 plants from each line, +/− SD, are shown. Statistical significance of differences between groups was determined by one-way ANOVA (with Tukey’s test). ** indicates statistical significance at p < 0.01 level. ‘ns’ denotes no statistically significant difference. A horizontal line above columns indicates data points sharing similar levels of statistical significance compared to the wild-type control.
