摘要:

目的 C3H家族基因在调控植物生长发育中起着重要作用,探究广金钱草C3H基因家族的特性及功能,为研究其在广金钱草生理和形态形成中的作用奠定基础。 方法 基于‘广药大1号’和野生广金钱草的转录组数据比较,鉴定广金钱草C3H家族基因,利用生物信息技术分析基因的理化性质、染色体位置、系统发育关系、保守基序和结构域,以及使用实时荧光定量PCR(RT-qPCR)技术分析C3H家族基因在广金钱草不同组织和品种中的表达模式,并对广金钱草C3H基因与类黄酮合成关键基因进行相关性分析,同时测定不同品种茎尖、茎基总黄酮含量。 结果 广金钱草C3H基因家族的27个成员分布在9条染色体上,多编码碱性、不稳定和亲水性蛋白质。系统进化分析显示,广金钱草C3H家族基因分为3个组群,同一组群成员之间相对保守;保守基序和结构域分析显示,数量出现最多的motif与生长素调控相关,广金钱草C3H家族成员存在与ANKYR等结构域协同作用的情况。表达模式分析显示,广金钱草C3H家族基因主要在广金钱草的茎中发挥作用,且在‘广药大1号’茎尖处高表达。相关性分析发现,广金钱草C3H家族基因表达量与类黄酮生物合成关键基因表达量呈正相关。总黄酮含量测定发现,在茎尖部位,‘广药大1号’的总黄酮含量显著高于野生匍匐广金钱草,在茎基情况相反。 结论 GsC3H家族基因可能通过调控黄酮类化合物在茎段的生物合成间接影响‘广药大1号’广金钱草的农艺性状。

Abstract:

Objective The C3H family genes play a significant role in regulating plant growth and development. Investigating the characteristics and functions of the C3H gene family in Grona styracifolia will lay a foundation for studying its roles in the physiological and morphological formation of this species. Method Based on the comparison of transcriptome data between ‘Guangyao Da 1’ and wild G. styracifolia, the C3H family genes were identified. Bioinformatics techniques were utilized to analyze the physicochemical properties, chromosomal positions, phylogenetic relationships, conserved motifs, and domains of these genes. real-time quantitative PCR (RT-qPCR) was applied to examine the expression patterns of the C3H family genes in different tissues and varieties of G. styracifolia. The correlation between C3H genes and key genes involved in flavonoid biosynthesis was analyzed. Additionally, the total flavonoid content in the stem tips and bases of different varieties were measured. Result The G. styracifolia C3H gene family consists of 27 members distributed across 9 chromosomes, primarily encoding basic, unstable, and hydrophilic proteins. Phylogenetic analysis shows that the G. styracifoliaC3H family genes are divided into three groups, with members in the same group being relatively conserved. Analysis of conserved motifs and domains indicates that the most frequently occurring motif is related to auxin regulation, and there is cooperative interaction with domains such as ANKYR among the G. styracifolia C3H family members. Expression pattern analysis reveals that the G. styracifoliaC3H family genes mainly function in the stems of it and are highly expressed at the stem tips of the ‘Guangyao Da 1’ variety. Correlation analysis found that the expressions of G. styracifolia C3H family genes are often positively correlated with key genes in flavonoid biosynthesis. Total flavonoid content measurement showed that at the stem tip, the total flavonoid content of ‘Guangyao Da 1’ is significantly higher than that of wild creeping G. styracifolia, while the opposite is true at the stem base. Conclusion The GsC3H family genes may indirectly influence the agronomic traits of ‘Guangyao Da 1’ G. styracifolia by regulating the biosynthesis of flavonoids in the stem segments.
