Expression pattern of wheat TaDof2/3/6 genes. a Expression patterns of TaDof2/3/6 genes during grain development of wheat cultivar Zhongmai 175 and in response to high and low nitrogen treatments. LN (low-nitrogen): without fertilization application after sowing; NN (normal nitrogen): fertilization with 180 kg/hm2; HN (high-nitrogen): fertilization with 240 kg/hm2. b Expression patterns of TaDof2/3/6 genes during grain development of wheat cultivars Zhongmai 175 and Jimai 22 and in response to drought stress. CK: the control group with two-irrigation at jointing and anthesis stages; DS: drought stress group without irrigation after sowing. Expression of the wheat Ubiqutin gene was used as a reference gene. Statistically significant differences between control group and treatment group were calculated by an independent Student’s t-tests: “*” p < 0.05; “**” p < 0.01
