Effects of molybdenum on expression of the ABA-dependent COR genes (Wrab15, Wrab17, Wrab18 and Wrab19) in Mo-efficient winter wheat cultivar ‘97003’ (A, C, E, G) and Mo-inefficient winter wheat cultivar ‘97014’ (B, D, F, H) under low-temperature stress. −Mo and +Mo treatments represent plants fertilized with 0 and 0·15 mg Mo [(NH4)6Mo7O24.4H2O] per kg soil, respectively. Error bars represent s.e. from n = 6 experiments. Different letters indicate significant differences at P < 0·05 as determined by ANOVA followed by Duncan's test.
