WebApr 11, 2024 · In pea, overexpression of GA3ox influenced GA biosynthesis, but it was timing- or localization-dependent . Previous studies also showed that overexpression of the early-step genes of GA biosynthesis, such as CPS and KS, did not affect the bioactive GAs but rather the GA intermediates [18,19]. WebSep 19, 2024 · Tomato has eight GA20ox and six GA3ox genes (Pattison et al., 2015). While none of the GA3ox genes was downregulated (Fig. S3), the expression levels of two GA20ox genes, GA20ox1 and GA20ox2 were suppressed (Fig. 1d). Surprisingly, the expression of GA20ox3 was strongly upregulated under water-deficit conditions.
