<i>sto-1</i> and <i>STO-OE</i> show diverse phenotypes.

Col, sto-1 and STO-OE were grown under SD conditions and different growth characteristics analyzed. (A) Seed germination as a percentage of total seeds analyzed; (B) hypocotyl length; (C) and (E) Seedling growth as measured by average hypocotyl length (n = 20–30) after 5 d on1/2 MS plates treated with BL (0–1000 nM) in SD; (D) and (F) Seedling growth as measured by average hypocotyl length (n = 20–30) after treatment with ACC (0–10 µM) for 3.5 days in darkness; (G) Appearance of adult rosette leaves on both adaxial and abaxial surfaces, with arrows indicating the position of leaf serration; (H–K) Flowering time of Col, sto-1 and STO-OE in LD and SD conditions. The average number of rosette leaves in LD (J) and SD (K) was also calculated (n = 15–28, * means p<0.05 and ** means p<0.01 in TTEST).
