Turnip mosaic virus (Tu MV ), the only potyvirus known to infect brassicas, is a devastating threatening many economically important brassica crops, including cabbage, Chinese oilseed rape and mustard. Tu disease, which was first discovered in United States, now found worldwide, especially Europe, Asia North America. results yield loss of up 70% has wide host range, infecting most cruciferous plants, as well non‐cruciferous species. This also characterized by high pathotype diversity because its highly variable genome structure been divided into 12 pathotypes. These characteristics, nonpersistent transmission mode 89 aphid species, mean disease difficult prevent through traditional methods such application chemicals, prompting researchers seek resistance for effective control. During last decade, extensive studies have conducted investigate inheritance, mapping cloning genes, several NB ‐ LRR or eIF ‐encoding loci with divergent molecular mechanisms uncovered. greatly facilitated breeding crops advanced our understanding virus−host interactions.
