Abstract

gene family is one of the largest transcription factor families involved in various physiological processes of plants. Flax () is an important stem fiber crop, and it is also an economically important crop in natural fiber and textile industries around the world. In this study, 105 genes were obtained by screening the whole genome of flax. There were 26 in group I, 68 in group II, 8 in group III and 3 in group UN. The characteristics of the WRKY motif and gene structure in each group are similar. The promoter sequence of genes includes photoresponsive elements, core regulatory elements and 12 cis-acting elements under abiotic stress. Similar to and plants, genes are evenly distributed on each chromosome, with segmental and tandem repeated events, which play a major role in the evolution of genes. The flax gene family is mainly concentrated in group I and group II. This study is mainly based on genome-wide information to classify and analyze the flax gene family, laying a foundation for further understanding the role of WRKY transcription factors in species evolution and functional analysis.

摘要

WRKY基因家族是参与植物各种生理过程的最大转录因子家族之一。亚麻（Linum usitatissimum）是一种重要的茎纤维作物，也是全球天然纤维和纺织工业中具有重要经济价值的作物。在本研究中，通过对亚麻全基因组进行筛选，获得了105个WRKY基因。其中，第I组有26个，第II组有68个，第III组有8个，未分组有3个。每组中WRKY基序和基因结构的特征相似。WRKY基因的启动子序列包括光响应元件、核心调控元件以及非生物胁迫下的12个顺式作用元件。与拟南芥（Arabidopsis thaliana）和水稻（Oryza sativa）植物相似，WRKY基因均匀分布在每条染色体上，存在片段重复和串联重复事件，这在WRKY基因的进化中起主要作用。亚麻WRKY基因家族主要集中在第I组和第II组。本研究主要基于全基因组信息对亚麻WRKY基因家族进行分类和分析，为进一步了解WRKY转录因子在物种进化和功能分析中的作用奠定基础。
