Abstract

Abstract Vegetables are an integral part of the human diet worldwide. Traditional breeding approaches have been used extensively to develop new cultivars of vegetables with desirable characteristics, including resistance/tolerance to biotic and abiotic stresses, high yield, and an elevated content of compounds beneficial to human health. The technological progress since the early 1980s has revolutionized our ability to study and manipulate genetic variation in crop plants. The development of high-throughput sequencing platforms and accompanying analytical methods have led to sequencing and assembly of a large number of plant genomes, construction of dense and ultra-dense molecular linkage maps, identification of structural variants, and application of molecular markers in breeding programs. Linkage mapping and genome-wide association mapping studies have been used to identify chromosomal locations of genes and QTLs associated with plant phenotypic variations important for crop improvement. This review provides up-to-date information on the status of genomics and marker-assisted improvement of vegetable crops with the focus on tomato, pepper, eggplant, lettuce, spinach, cucumber, and chicory. For each vegetable crop, we present the most recent information on genetic resources, mapping populations, genetic maps, genome sequences, mapped genes and QTLs, the status of marker-assisted selection and genomic selection, and discuss future research prospects and application of novel techniques and approaches.

蔬菜作物基因组学与标记辅助改良
蔬菜是世界范围内人类饮食中不可或缺的一部分。传统育种方法已被广泛用于开发具有理想特性的蔬菜新品种,包括对生物和非生物胁迫的抗性/耐受性、高产和对人体健康有益的化合物含量的提高。20世纪80年代初以来的技术进步彻底改变了我们研究和操纵作物遗传变异的能力。随着高通量测序平台和相关分析方法的发展,大量植物基因组的测序和组装,密集和超密集分子连锁图谱的构建,结构变异的鉴定,以及分子标记在育种计划中的应用。连锁作图和全基因组关联作图研究已被用于鉴定与作物改良重要的植物表型变异相关的基因和qtl的染色体位置。本文综述了蔬菜作物基因组学和标记辅助改良的最新进展,重点介绍了番茄、辣椒、茄子、生菜、菠菜、黄瓜和菊苣。本文介绍了蔬菜作物的遗传资源、定位群体、遗传图谱、基因组序列、定位基因和qtl、标记辅助选择和基因组选择的研究现状,并对未来的研究前景和新技术、新方法的应用进行了展望。

期刊介绍: Critical Reviews in Plant Sciences focuses on presenting in-depth and up-to-date reviews of timely and/or cutting-edge subjects in the broad discipline of plant science, ranging from molecular biology/biochemistry through the areas of cell biology, plant pathology and physiology, genetics, classical botany, and ecology, to practical agricultural applications. Articles in the journal provide an up-to-date literature base for researchers and students, pointing the way towards future research needs. The journal is also a significant source of credible, objective information to aid decision makers at all levels.
