Abstract:Using maize inbreed line Zheng58 for experimental material, bioinformatic and expression pattern analysis of 11 ZmbZIP genes were performed at the experimental conditions of 200 mmol/L NaCl, 20% PEG6000, 4 ℃ and nitrate or ammonium deficiency stresses. The phylogenetic tree analysis showed that 11 ZmbZIPs could be subdivided into 2 subgroups. RT-PCR results revealed that different expression patten of ZmbZIP were detected in different tissues, indicating different biological roles in plant growth and development. Under simulated salt, drought, low temperature and nitrogen stress, ZmbZIP were widely regulated, ZmbZIP1, ZmbZIP6 and ZmbZIP13 of subgroup I were obviously upregulated by salt by two fold, and inhibited by PEG6000, while ZmbZIP38, ZmbZIP77, ZmbZIP112 and ZmbZIP124 of subgroup II were upregulated by salt, PEG6000 and low temperature stresses. And, ZmbZIP1, ZmbZIP6 and ZmbZIP134 were obviously downregulated by nitrate deficient stress, while upregulated by ammonium deficient stress, indicating different biological function roles of these genes in responsive to various stresses.
