Abstract：
The Whirly (WHY) gene family, functioning as transcription factors, plays an essential role in the regulation of plant metabolic responses, which has been demonstrated across multiple species. However, the WHY gene family and its functions in soybean remains unclear. In this paper, we conducted genome-wide screening and identification to characterize the WHY gene family. Seven WHY members were identified and randomly distributed across six chromosomes. The phylogenetic evolutionary tree of WHY genes in soybean and other species was divided into five clades. An in-depth analysis revealed that segmental duplications significantly contributed to the expansion of GmWHYs, and the GmWHY gene members may have experienced evolutionary pressure for purifying selection in soybeans. The analysis of promoter Cis-elements in GmWHYs suggested their potential significance in addressing diverse stress conditions. The expression patterns of GmWHYs exhibited tissue-specific variations throughout the different stages of soybean development. Additionally, six GmWHY genes exhibited different responses to low phosphate stress. These findings will provide a theoretical basis and valuable reference for the future exploration of WHY gene function.
摘要：
Whirly（为什么）基因家族，作为转录因子，在植物代谢反应的调节中起着至关重要的作用，这已经在多个物种中得到了证明。然而,大豆中的WHY基因家族及其功能尚不清楚。在本文中,我们进行了全基因组筛选和鉴定,以确定WHY基因家族的特征.确定了七个WHY成员，并随机分布在六个染色体上。大豆和其他物种中WHY基因的系统发育进化树分为五个进化枝。深入分析显示，分段重复显著促进了GmWHYs的扩展，GmWHY基因成员可能经历了大豆纯化选择的进化压力。对GmWHYs中启动子Cis元件的分析表明，它们在解决多种胁迫条件方面具有潜在的意义。GmWHYs的表达模式在大豆发育的不同阶段都表现出组织特异性变化。此外,六个GmWHY基因对低磷酸盐胁迫表现出不同的反应。这些发现将为今后探索WHY基因功能提供理论依据和有价值的参考。
