Abstract:

To explore the effect of various abiotic stresses on expression pattern of ZmbZIP, maize inbreed line Zheng58 was adopted as test materials, and five abiotic stresses (200 mmol·L -1 NaCl, 20% PEG6000, 4 ℃ low temperature, nitrate or ammonium deficiency stresses) were set, and expression of G group genes of bZIP family were systematically detected. Phylogenetic tree analysis showed that G group genes were subdivided into 3 subgroups. qRT-PCR analysis showed that 15 ZmbZIP genes had different expression pattern in various maize tissues, indicating their important roles during growth and development process in maize. Under different stresses of simulated salt, drought, low temperature and nitrogen deficiency, 20 ZmbZIP genes were widely regulated, indicating that most of those genes were involved in response to stress signaling pathway.

Key words: bZIP transcription factor, abiotic stresses, gene expression, maize
