Abrogation of LSU constrains stomatal closure during abiotic stress conditions. Twelve-day-old WT and amiR-LSUa–c seedlings grown in +S or –S conditions were transferred to the same media supplemented with ABA or mock treated for 3 h. Stomatal aperture was quantified as the ratio of ostiol width to length (Rwl). Error bars correspond to the SD of ≥3 biologically independent measurements (n ≥30 stomata), and significant differences were assessed by the Student’s t-test relative to the WT in the same conditions (***P<0.001).
