Abstract

Chrysanthemum is a well-known ornamental plant with numerous uses. is a large family of transcription factors known for a variety of functions ranging from stress resistance to plant growth and development. Due to the limited research on the family in chrysanthemums, we examined them for the first time in . A total of 138 genes were identified, which were classified into three groups. Group III in contains 53 members, which is larger than group III of . The number of introns varied from one to nine in the gene family. The "WRKYGQK" motif is conserved in 118 members, while other members showed slight variations. AuR and GRE responsive -acting elements were located in the promoter region of members, which are important for plant development and flowering induction. In addition, the W box was present in most genes; the recognition site for the gene may play a role in autoregulation and cross-regulation. The expression of the most variable 19 genes in terms of different parameters was observed at different stages. Among them, 10 genes were selected due to the presence of CpG islands, while nine genes were selected based on their close association with important genes related to floral traits. and exhibit differential expression at flowering stages in the capitulum, while methylation is detected in three genes, including , and Our results provide a basis for further exploration of members to find their functions in plant growth and development, especially in flowering traits.

摘要

菊花是一种用途广泛的著名观赏植物。 是一个庞大的转录因子家族，以从抗逆到植物生长发育等多种功能而闻名。由于对菊花中 家族的研究有限，我们首次在 中对它们进行了研究。共鉴定出138个 基因，这些基因被分为三组。 中的第三组包含53个成员，比 的第三组更大。 基因家族中内含子的数量从1到9不等。118个成员中“WRKYGQK”基序保守，而其他成员有轻微变异。AuR和GRE响应作用元件位于 成员的启动子区域，这对植物发育和开花诱导很重要。此外，大多数基因中存在W盒； 基因的识别位点可能在自调控和交叉调控中起作用。观察了19个在不同参数方面变化最大的基因在不同阶段的表达。其中，由于存在CpG岛而选择了10个基因，而另外9个基因是基于它们与与花性状相关的重要 基因的密切关联而选择的。 和 在头状花序的开花阶段表现出差异表达，而在三个基因中检测到甲基化，包括 、 和 。我们的结果为进一步探索 成员以发现它们在植物生长发育，特别是在花性状中的功能提供了基础。
