摘要：

组氨酸磷酸转运蛋白HP(histidine phosphotransfer proteins)在植物的生长发育调控及逆境胁迫应答中发挥重要作用。为理解HP基因在小麦基因组中的进化特征和功能,研究通过生物信息学分析鉴定普通小麦的HP基因家族成员,对其理化性质、进化特征、基因结构、顺式作用元件以及在逆境胁迫条件下的表达模式进行了分析。结果表明,在小麦基因组鉴定到31个HP基因,编码蛋白质序列包括116~200 个氨基酸。通过和其他植物的HP蛋白比较以及对蛋白结构、基因结构和基序的分析,显示小麦HP家族基因序列具有保守性。顺式作用元件预测表明,HP基因具有光、植物激素、干旱、低温等非生物胁迫响应相关的启动子调控元件。热图分析表明,HP基因在应答非生物胁迫中表达模式存在多样性;qRT-PCR分析表明,TaHP5-6B基因在低磷胁迫下受到强烈的诱导表达。综上所述,小麦全基因组鉴定的HP家族基因是非生物胁迫响应的重要基因资源。

Abstract:

HP (histidine phosphotransfer proteins) plays an important role in regulating growth and development and responding to stress in plants. In order to understand the evolution and function of HP genes in wheat genome, this study identified the HP gene family for Triticum aestivum by the bioinformatics method, and analyzed the physicochemical properties, evolutionary characteristics, gene structure, cis-acting elements, and expression patterns under stress. The results showed that 31 HP genes were identified. The length of amid acids of HP proteins ranged from 116 to 200. Comparison with HP proteins of other plants and analysis of protein structure, gene structure and motif showed that sequences of HP gene family were conserved in wheat. Analysis of cis-acting elements revealed that the promoter regions of HP genes contained regulatory elements involved in abiotic stress, such as light, phytohormone, drought and low temperature. Heatmap analysis showed that HP genes significantly differed in the expression levels under abiotic stress. qRT-PCR analysis indicated that TaHP5-6B was strongly induced under low phosphorus stress. In conclusion, HP family genes identified at the genome-wide level are important gene resources associated with abiotic stress response in wheat.

Key words: wheat, histidine phosphotransfer protein, conserved sequence, HP gene family, low phosphorus stress
