摘要:

果实品质是葡萄育种的核心目标,其相关性状多为多基因控制的数量性状,易受遗传背景和环境因素共同影响,解析其遗传基础对葡萄分子设计育种具有重要意义。本研究系统综述葡萄果实品质性状(大小、质地、糖酸、颜色、无核和香气等)的遗传特性,梳理近30年来基于双亲分离群体连锁分析和自然群体关联分析鉴定品质性状QTL/候选基因的研究进展。葡萄果实大小、形状、质地等为典型多基因数量性状,具有较高广义遗传力;颜色、无核性、玫瑰香味等兼具质量与数量双重遗传特性,由主效基因联合微效基因调控,且多数品质性状的表型表达受栽培措施、光照、温度等环境因子显著影响。连锁分析方面,利用约60个以F1代为主的杂交群体,共定位果实品质相关QTL约386个,其中,糖酸含量相关QTL数量最多,且在第18连锁群鉴定到无核、果实大小、质地等性状的主效QTL,第5连锁群存在玫瑰香味主效QTL;同时挖掘出VviAGL11DXSMYBA1/2等关键候选基因,明确其在无核性、玫瑰香味、果实颜色调控中的核心作用。关联分析方面,候选基因关联分析证实VvMybA基因簇、DXS等基因的序列多态性与果实颜色、玫瑰香味等性状显著关联,且部分基因存在多效性;全基因组关联分析已鉴定出大量与果实品质相关的SNP位点和结构变异,其中,结构变异在部分性状遗传调控中的贡献高于SNP。目前,分子标记在葡萄品质育种中的应用仍局限于主效基因控制的颜色、无核性、玫瑰香味等性状,果实大小、质地等复杂数量性状尚未实现分子标记辅助选择的实际应用。当前葡萄品质性状基因定位仍面临定位精度不足、多组学数据整合困难、多基因互作网络解析复杂、分子标记稳定性差等问题。未来需依托超级泛基因组、高通量表型鉴定平台,结合深度学习、基因编辑等技术,加强基因-环境互作研究,提高QTL定位精度和基因功能解析效率,构建高效的分子育种技术体系,为葡萄优质品种培育提供理论支撑和技术保障。本文旨在为后续优质葡萄品种的分子设计育种提供全面的文献参考与理论支撑。

Abstract:

Berry quality is a core objective of grapevine breeding. Most related traits are quantitative characteristics controlled by multiple genes, which are susceptible to the combined effects of genetic background and environmental factors. Deciphering the genetic basis of these traits is of great significance for molecular design breeding of grapes. This study systematically reviews the genetic characteristics of grape berry quality traits (e.g., berry size, texture, sugar and acid content, color, seedlessness, and aroma) and summarizes the research progress over the past three decades in identifying QTLs/candidate genes for quality traits using linkage analysis in bi-parental segregating populations and association analysis in natural populations. Grape berry size, shape and texture are typical polygenic quantitative traits with high broad-sense heritability; traits such as berry color, seedlessness and muscat flavor exhibit dual genetic characteristics of both qualitative and quantitative traits, which are regulated by major genes combined with minor genes. In addition, the phenotypic expression of most quality traits is significantly affected by environmental factors such as cultivation practices, light and temperature. In terms of linkage analysis, a total of approximately 386 QTLs associated with grape berry quality traits were mapped using about 60 hybrid populations dominated by F₁ generations, among which the number of QTLs related to sugar and acid content was the largest. Major QTLs for seedlessness, berry size, texture and other traits were identified on linkage group 18, and a major QTL for muscat aroma was detected on linkage group 5. Meanwhile, key candidate genes such as VviAGL11, DXS and MYBA1/2 were excavated, and their core regulatory roles in seedlessness, muscat aroma and berry color were clarified. For association analysis, candidate gene association analysis confirmed that the sequence polymorphisms of gene clusters such as VvMybA and genes including DXS were significantly associated with fruit color, muscat aroma and other traits, and some genes exhibited pleiotropy. Genome-wide association analysis has identified a large number of single nucleotide polymorphism (SNP) loci and structural variations (SVs) related to berry quality traits, among which SVs contribute more to the genetic regulation of some traits than SNPs. At present, the application of molecular markers in grape quality breeding is still limited to traits controlled by major genes such as berry color, seedlessness and muscat aroma, and marker-assisted selection has not been practically applied to complex quantitative traits such as berry size and texture. Currently, the gene mapping of grape berry quality traits is still faced with challenges such as insufficient mapping accuracy, difficulties in multi-omics data integration, complexity in deciphering multi-gene interaction networks, and poor stability of molecular markers. In the future, relying on super pan-genome and high-throughput phenotyping platforms, combined with technologies such as deep learning and gene editing, it is necessary to strengthen research on gene-environment interactions, improve the accuracy of QTL mapping and the efficiency of gene function analysis, and construct an efficient molecular breeding technology system, so as to provide theoretical support and technical guarantee for the cultivation of high-quality grape varieties. This paper aims to offer a comprehensive literature reference and theoretical foundation for subsequent molecular design breeding of premium grape cultivars.
