FIG 4.

Exogenous NO inhibits the gene and protein expression of ACO induced by heat stress. (A) aco gene expression after different lengths of heat stress. (B) Protein expression level of ACO after different lengths of heat stress. (C) Effects of exogenous NO on aco gene expression after heat stress. (D) Effects of exogenous NO on the expression of the ACO protein after heat stress. The values are the mean ± SE of three independent experiments. Different letters indicate significant differences for the comparison of samples (P < 0.05 according to Duncan’s test).
