Root elongation in jmj30 jmj32 double mutants is less sensitive to ABA. (A–C) Representative images of wild-type (WT) and jmj30-2 jmj32-1 plants in the absence and presence of ABA. Wild-type and jmj30-2 jmj32-1 seeds were sown on half-strength MS with 1% sucrose and stratified at 4°C for 3 days. Plants were grown under 24 h of light for 3 days and then transplanted onto half-strength MS plates with 1% sucrose supplemented with 0 µM ABA (A), 5 µM ABA (B), or 10 µM ABA (C) and grown vertically under 24 h of light for an additional 7 days. Bar = 1 cm. (D) Quantification of root length in wild-type and jmj30-2 jmj32-1 plants shown in (A–C). Asterisks indicate significant differences based on two-tailed Student’s t-test; p < .01; NS, nonsignificant. Values represent mean ± SD of 24 plants.
