a virus-induced gene silencing (VIGS) approach to knockdown gene SlSLD expression is used in tomato leaves involving transformation via Agrobacterium GV3101, chilling resistance is evaluated for wild-type and mutangt plant seedlings, determination of the mutant phenotype, detailed overview. After exposure to 4°C, SlSLD-silenced mutant tomato plants are severely damaged. Exposure to low temperature severely damages chloroplasts in SlSLD-silenced plants
