Screening <i>Brassica rapa</i> for broad-spectrum resistance to Turnip mosaic virus.

ABSTRACT: Turnip mosaic virus (TuMV) poses a major threat to Brassica crops like Chinese cabbage, causing significant economic losses. A viable and effective strategy to manage such diseases is by improvement of genetic-based viral resistance. To achieve this, it is important to have detailed and wide-ranging genetic resources, necessitating genetic exploration. To identify useful TuMV resistant genetic resources, we screened geographically and genetically diverse resources including over 90 accessions from the Tohoku Univ. Brassica Seed Bank against eleven TuMV isolates phylogenetically classified into five clusters. Two USA accessions exhibited no or only slight symptoms with no virus protein detected in virus-inoculated and non-inoculated upper leaves, suggesting an extreme resistan
