Abstract

Among the largest transcription factor families in plants, bZIPs are crucial for various developmental and physiological processes, particularly abiotic stress resistance. has become a model for understanding stress resistance mechanisms. In this study, we identified 90 bZIP transcription factors in the genome. were classified into 13 groups based on references to bZIPs. Members in the same group shared similar motifs and gene structure pattern. In addition, gene duplication analysis indenfied 37 pairs of segmental duplicated genes and none tandem duplicated genes in suggesting segmental duplication contributed to the expansion of the bZIP gene family. Moreover, the number of genes (39) exhibiting higher expression in roots was significantly more than that in other organs. Twelve genes were upregulated in response to dehydration stress. In conclusion, our study advances the current understanding of genes and provide a number of candidates for functional analysis of drought tolerance in .

摘要

在植物中最大的转录因子家族中，bZIPs对于各种发育和生理过程至关重要，尤其是在非生物胁迫抗性方面。已成为理解胁迫抗性机制的模型。在本研究中，我们在基因组中鉴定出90个bZIP转录因子。根据对bZIPs的参考将其分为13组。同一组中的成员共享相似的基序和基因结构模式。此外，基因复制分析在中鉴定出37对片段重复基因且无串联重复基因，这表明片段重复促成了bZIP基因家族的扩展。而且，在根中表现出较高表达的基因数量（39个）显著多于其他器官。12个基因在脱水胁迫下上调。总之，我们的研究推进了当前对基因的理解，并为中耐旱性功能分析提供了许多候选基因。
