摘要:

目的 GSTF转运蛋白参与植物花青素苷的转运过程,研究其对彩色马蹄莲(Zantedeschia hybrida)佛焰苞着色和花青素苷积累的作用及其分子机制,为彩色马蹄莲花青素苷转运机制解析提供理论依据,为新品种选育提供有效基因资源。 方法 基于课题组前期对彩色马蹄莲转录组数据的分析,筛选并克隆彩色马蹄莲佛焰苞花青素苷转运相关基因ZhGSTF,分析其进化关系和序列特征,并测定在不同品种佛焰苞中的基因表达量和花青素苷含量。同时利用病毒诱导的基因沉默(virus induced gene silencing, VIGS)技术构建ZhGSTF沉默体系,比较沉默后佛焰苞表型、基因表达和3个类黄酮合成途径下游结构基因表达量的变化。 结果 ZhGSTF的CDS长度为666 bp,编码221个氨基酸。系统进化树分析表明,ZhGSTF与其他物种花青素苷转运相关的GST聚为一类;氨基酸序列比对显示,ZhGSTF与紫苏(Perilla frutescens)PfGST1相似性最高。ZhGSTF在玫红色‘佳人’和橙色‘奥迪安’中表达量均显著高于黄色‘金城’,在白色‘范图拉’中显著低表达,ZhGSTF在4个品种中的表达量与其花青素苷积累趋势一致。经VIGS沉默后,ZhGSTF表达量显著下调,佛焰苞表型发生明显褪色,而ZhGSTF的沉默对ZhANSZhANRZhDFR表达量无显著影响。 结论 彩色马蹄莲ZhGSTF在佛焰苞着色过程中促进花青素苷积累并影响其呈色。

Abstract:

Objective GSTF transporter is involved in the transport process of anthocyanins in plants. Studying its role and molecular mechanism in the coloration of spathe coloration and anthocyanin accumulation of Zantedeschia hybrida may provide theoretical basis for the analysis of anthocyanin transport mechanism of Z. hybrida and provide effective gene resources for breeding new varieties. Method Based on the analysis of transcriptome data of Z. hybrida, the gene ZhGSTF related to anthocyanin transport in the spatula of Z. hybrida was screened and cloned, its evolutionary relationship and sequence characteristics were analyzed, and the gene expressions and anthocyanin contents in different varieties of spatula were determined. Concurrently, virus induced gene silencing technology was used to construct ZhGSTF silencing system, and the variations of phenotype, gene expression and gene expression of three flavonoid synthesis pathways downstream after silencing were compared. Result The CDS of ZhGSTF gene was 666 bp long, encoding 221 amino acids. Phylogenetic tree analysis showed that ZhGSTF was clustered with GST related to anthocyanin transport in other species. The amino acid sequence comparison showed that ZhGSTF had the highest similarity with Perilla frutescens PFGST1. The expressions of ZhGSTF in rose ‘Lover’ and orange ‘Odean’ was significantly higher than that in yellow ‘Jincheng’, and it was significantly lower in white ‘Ventura’. The expressions of ZhGSTF in the four varieties were consistent with the accumulation trend of anthocyanins. After VIGS silencing, the expressions of ZhGSTF significantly decreased, and the phenotype of spathe faded obviously, but ZhGSTF silencing had no significant effect on the expression of ZhANS, ZhANR and ZhDFR. Conclusion The Z. hybridaZhGSTF promotes the accumulation of anthocyanins and affects its coloration in the process of spathe coloration.
