VIGS of 3 key genes. A shows the albino phenotype of pTRV2::CLA plants; D, G, and J show the silencing efficiency of pTRV2::GhF6'H1, pTRV2::Gh3AT1 and pTRV2::GhPER55 plants; B and C show the normal pTRV2::00 plant phenotypic changes after the control (CK) and drought stress (DS) treatments; E and F show the phenotypic changes in pTRV2::GhF6'H1 plants after the control treatment (CK) and drought stress treatment (DS); H and I show the phenotypic changes in pTRV2::Gh3AT1 plants after the control treatment (CK) and drought stress treatment (DS); and K and L show the phenotypes of pTRV2::GhPER55 plants after the control treatment (CK) and drought stress (DS), respectively. Two-way analysis of variance was used for statistical analysis. * represents P < 0.05, a significant difference; ** represents P < 0.01, a highly significant difference; *** represents P < 0.001, an extremely significant difference
