FIG 1.

Knockdown of the spds gene decreases the content of GAs. GA contents in the WT, the empty vector control (control silence (Control si)), two spds knockdown strains, and strains supplied with 1 mM spermidine (Spd) from 7-day-old liquid mycelia were determined. The values presented are the means ± standard deviations (SD) of data from three independent experiments. Different letters indicate significant differences between the lines (P < 0.05, according to Duncan’s multiple-range test). D.W, dry weight.
