Abstract

Transcription factors are regulatory proteins known to modulate gene expression. These are the critical component of signaling pathways and help in mitigating various developmental and stress responses. Among them, bZIP, BBR, and BZR transcription factor families are well known to play a crucial role in regulating growth, development, and defense responses. However, limited data is available on these transcription factors in Triticum aestivum. In this study, bZIP, BBR, and BZR sequences from Brachypodium distachyon, Oryza sativa, Oryza barthii, Oryza brachyantha, T. aestivum, Triticum urartu, Sorghum bicolor, Zea mays were retrieved, and dendrograms were constructed to analyze the evolutionary relatedness among them. The sequences clustered into one group indicated a degree of evolutionary correlation highlighting the common lineage of cereal grains. This analysis also exhibited that these genes were highly conserved among studied monocots emphasizing their common ancestry. Furthermore, these transcription factor genes were evaluated for envisaging conserved motifs, gene structure, and subcellular localization in T. aestivum. This comprehensive computational analysis has provided an insight into transcription factor evolution that can also be useful in developing approaches for future functional characterization of these genes in T. aestivum. Furthermore, the data generated can be beneficial in future for genetic manipulation of economically important plants.

摘要

转录因子是已知调节基因表达的调节蛋白。它们是信号通路的关键组成部分，有助于减轻各种发育和应激反应。其中，bZIP、BBR 和 BZR 转录因子家族在调节生长、发育和防御反应中起着至关重要的作用。然而，关于小麦中的这些转录因子的信息有限。在这项研究中，从拟南芥、水稻、稻属、长穗稻、小麦、小麦属、高粱、玉米中检索了 bZIP、BBR 和 BZR 序列，并构建了系统发育树来分析它们之间的进化关系。序列聚类成一组表明存在一定程度的进化相关性，突出了谷物的共同谱系。该分析还表明，这些基因在研究的单子叶植物中高度保守，强调了它们的共同祖先。此外，还评估了这些转录因子基因在小麦中的保守基序、基因结构和亚细胞定位。这项全面的计算分析深入了解了转录因子的进化，这也有助于为未来在小麦中对这些基因进行功能表征开发方法。此外，生成的数据将来也可用于对经济上重要的植物进行遗传操作。
