Under different stresses, we tested the expression of citrate synthase gene in rapeseed leaf by using semi-quantitative PCR. The expression of citrate synthase gene had no obvious change in stresses of salt, dark, high illumination, while was increased at different time in treatments of water logging, drought, IAA, and 6-BA. Interestingly the effect of ABA was contrary to that of IAA. In the treatment of sclerotium blight, the expression of citrate synthase gene was depressed. There was a saddle curve of citrate synthase gene expression in the treatment of gibberellin.
