摘要:

本研究旨在鉴定月季C2H2锌指蛋白基因家族成员,深入解析其分子特征与表达模式,为阐明C2H2蛋白在月季生长发育及胁迫响应中的功能机制奠定基础。利用生物信息学方法,在月季基因组中共鉴定到43个C2H2基因,分布于7条染色体上,可分为5个亚家族。共线性分析显示,月季与拟南芥存在41对共线性基因对,月季基因组内部存在10对基因对。保守基序分析鉴定出5个基序,其中Motif 1为核心基序。启动子子区域的分析发现了多种与脱落酸应答、厌氧胁迫、光周期等相关的顺式作用元件,预示着该基因家族在植物生理调控中的广泛作用。蛋白质互作分析表明,29个C2H2基因家族成员之间存在互作关系,其中RcC2H2zfp7处于核心节点。组织表达分析显示,该家族成员在根组织中表达量最高,雄蕊次之,提示了它们在根系发育和生殖生长中的重要功能。本研究系统解析了月季C2H2锌指蛋白基因家族的基本特征与表达模式,为后续深入探究其在月季重要性状调控中的分子机制提供了理论参考和候选基因依据。

Abstract:

This study aims to identify the C2H2 zinc finger protein gene family members in rose (Rosa chinensis) using bioinformatics approaches, and to analyze their physicochemical properties, chromosomal localization, gene structures, and expression patterns, thereby providing a foundation for understanding the functional mechanisms of C2H2 proteins. A total of 43 C2H2 genes were identified in rose, distributed across seven chromosomes and classified into five subfamilies. Synteny analysis revealed 41 collinear gene pairs between rose and Arabidopsis thaliana, and 10 collinear gene pairs within the rose genome. Conserved motif analysis identified five motifs, among which Motif 1 was the core motif. Promoter regions contained various cis-acting elements associated with abscisic acid response, anaerobic stress, photoperiod, and others. Protein interaction analysis indicated that 29 C2H2 gene family members exhibited interactions, with RcC2H2zfp7 serving as a central hub node. Tissue expression analysis revealed that members of this gene family exhibited the highest expression levels in roots, followed by stamens. This study systematically elucidates the basic characteristics and expression patterns of the C2H2 zinc finger protein gene family in rose, providing a theoretical reference for further exploration of their functions in growth, development, and stress responses.
