Regulation of GA20ox and GA2ox Expression by GA in pro∆GRAS.
qRT-PCR analysis of GA20ox1 (A) and GA2ox4 (B) expression. Seedlings were treated with 10 mg/L PAC for 3 d, followed by one application of GA3 (1 or 100 μM). RNA was extracted from young leaves and analyzed. Values (gene-to-TUBULIN ratios) are means of three biological replicates ± se.
