摘要

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

MV 导致产量损失高达70％，具有宽的宿主范围，感染最芥菜植物，以及许多非十字花叶种类。该病毒的特征还具有高局部分集，因为其高度可变的基因组结构，并且已被分成12个病理型。这些特征以及其非蚜虫物种的非倾向传输模式，意味着这种疾病难以通过传统方法，例如应用化学品的应用，促使研究人员寻求有效控制的宿主阻力。在过去十年中，已经进行了广泛的研究来调查TU的遗传，绘图和克隆 MV 抗性基因，以及几个 NB - LRR - 或者 EIF - 已经发现了具有发散分子机制的基因座。这些研究极大地促进了芸苔作物的抗性育种，并提出了对病毒的理解？宿主相互作用。
