Abstract:

Brassicaceae vegetables,such as Chinese cabbage,Cabbage,mustard,and radish,serve as globally significant economic crops,playing an indispensable role in nutritional health,agricultural economies,and ecological balance. However,challenges including their complex genomic architecture (e.g.,polyploidy,abundant repetitive sequences,and gene redundancy)and low genetic transformation efficiency have hindered the elucidation of regulatory mechanisms for critical agronomic traits and their application in molecular breeding. In recent years,rapid advancements in functional genomics have provided abundant genetic resources and theoretical foundations for the targeted improvement and efficient integration of superior traits in Brassicaceae vegetables,such as high yield,stress tolerance,disease resistance,and enhanced functional nutrition quality. This review systematically summarizes major progress in functional genomics research on Brassicaceae vegetables,analyzes the severe challenges currently faced,identifies critical challenges including low genome assembly accuracy,difficulties in multi-omics data integration,and limited gene editing efficiency,and discusses the immense application prospects of the development of optimized technologies-such as third-generation sequencing,single-cell omics,and CRISPR-Cas systems-in accelerating the development of novel cultivars with improved stress resilience,productivity,and functional nutritional profiles.

Key words: Brassicaceae, vegetable, multi-omics analysis, disease resistance, nutritional quality, functional genomics
