Overexpression of PpGA20ox1, PpGA20ox2, PpGA3ox1 and PpGA2ox6 in Arabidopsis or tobacco. Photograph (A) and height (D) of 50-day-old seedlings of WT, empty vector (EV) control, and lines overexpressing PpGA20ox1 and PpGA20ox2 in wild-type background, from left to right). Photograph (B) and height (E) of 42-day-old seedlings of WT, overexpression of PpGA20ox1 and PpGA20ox2 in ga20ox mutant background, and ga20ox mutant, from left to right. Photograph (C) and height (F) of 40-day-old seedlings of WT, EV control, and two lines overexpressing PpGA3ox1 in wild-type background, from left to right). Photograph (G) and height (H) of tobacco overexpressing PpGA2ox6. Different lowercase letters indicate significant differences according to Fisher’s LSD test (P < 0.05)
