Figure 2: Overexpression of SlGRAS7 alters responsiveness to GA3 and IAA. (a) Quantitative RT-PCR analysis of SlGRAS7 from 15 days of WT seedlings treated with 20 μM GA3 and 20 μM IAA. (b) Phenotypes of 15 days of WT and SlGRAS7-OE L2 seedlings grown on an MS/2 medium containing (0 μM, 0.5 μM, 10 μM, and 20 μM GA3). (c) Primary root length of WT and SlGRAS7-OE seedlings shown in (b). (d) Hypocotyl length of WT and SlGRAS7-OE seedlings shown in (b). (e) Plant height of WT and SlGRAS7-OE seedlings shown in (b). Asterisks show the significant differences using Student’s -test (, ).
