Background: Brassica contains a variety of economically important crops. In recent years, with the rapid development of DNA sequencing technology and the continuous reduction of sequencing costs, whole-genome resequencing has become an important tool for Brassica research.

Main contents: This paper briefly introduces the current status of whole-genome sequencing in Brassica plants and some important progresses made in using whole-genome resequencing technology to study the domestication origin, environmental adaptations and the molecular basis of important traits of Brassica plants, including the fully sequenced 8 Brassica plant genomes, the use of the whole-genome resequencing technology in studying the domestication origin and relationship of Brassica oleracea, B. rapa, B. nigra and other Brassica species, and the identification of genes related to the adaptations to disease, rhythm and mineral nutrients, pigment synthesis, male sterility, and important production traits of Brassica plants. The research progresses introduced in this paper not only demonstrates the advantages of whole-genome resequencing technology in the study of Brassica plants in comparison with previous methods based on mitochondrial DNA and chloroplast DNA markers, but also provides important theoretical and technical support for future breeding of new Brassica crop varieties with improved environmental adaptability and excellent production traits.

Perspectives: As a relatively new research tool, whole-genome resequencing technology will be further widely adopted in future research of Brassica plants, its impact on the basic biological research and the breeding of new varieties of Brassica plants will be demonstrated.

Key words: Brassica, whole-genome resequencing, research progress, adaptation, traits
