The efficiency of virus-induced gene silencing in the cotton seedlings. A The albino change on the plants under being inoculated with TRV: PDS after 14 days. B Expression levels of the knocked gene in WT and VIGS-plants under normal conditions (control), drought and salt stress. Bar indicates the standard error (SE). Different letters indicate the significant differences between the wild type (WT) and the VIGS-plants (ANOVA; P < 0.05)
