Drought tolerance analysis of theGh4CL7-silencing cotton plants.aRepresentative phenotypes of theTRV:00(CK) andTRV:Gh4CL7(VIGS) plants after 3 weeks of drought treatment.b-cLeaf RWC and chlorophyll contents of CK and VIGS plants under drought stress.d-eComparison of stomata in the CK and VIGS plants.fWater loss rate of detached leaves from the CK and VIGS plants.g-hComparison of H₂O₂and MDA contents in the CK and VIGS plants.iActivities of antioxidative enzymes in the CK and VIGS plants. Mock, normal growth conditions; drought, 3 weeks of water deficit conditions. Statistical significance was determined by the student test. * and ** represent significant atP < 0.05 andP < 0.01, respectively
