Modification of flower architecture and reduction in seed number in the ta-siRNA biosynthesis mutant, rdr6, under drought stress. (a) Two-week-old rdr6 and wild-type plants were subjected to drought stress treatment for one week and then rewatered. Seed number in the 1st through the 5th siliques was counted (n = 12). Siliques were numbered starting at the basal end of the main shoot. (b) Siliques in plants subjected to drought stress followed by rewatering. (c) Floral architecture in drought-stress and nonstressed wild-type, rdr6, ARF3pro:ARF3, and ARF3pro:ARF3mut plants. Flowers in rdr6 and ARF3pro:ARF3 plants have a slightly exerting stigma phenotype under nonstressed conditions. In contrast, flowers in rdr6 and ARF3pro:ARF3mut plants under drought stress exhibit short stamens, as shown as white arrows. (d) Average length of the stigmas and stamens in drought-stressed and nonstressed WT, rdr6, ARF3pro:ARF3, and ARF3pro:ARF3mut plants.
