Brassicaceae family includes economically important plants such as vegetables, oil plants, and ornamental plants. Turnip mosaic virus (TuMV) is a virus threatening many economically important brassica crops. Especially, it has a very large host range among Brassica group plants and it can cause infection in 318 plant species from 156 genera. In the comprehensive studies conducted, dominant and recessive genes were identified in B. rapa (retr01, ConTR01, BcTuR3, rnt1, TuRBCH01, retr02, trs, TuMV-R, TuRB01b, TuRB07, TuRBCS01), in B. napus (TuRB01, TuRB02, TuRB03, TuRB04, TuRB05) and B. juncea (TuRBJU01, retr03). Studies conducted have shown that the genetic mechanism of resistance to TuMV is related to the host and pathogen strain. It is important to use the revealed resistance genes in breeding studies for Brassica species to prevent the disease. Identification and mapping of TuMV resistant genes in cabbage (B. oleracea), which is one of the important winter vegetables in the world and especially in Turkey, is required to prevent losses due to TuMV infection in cabbage. Therefore, studies on the resistance mechanism of TuMV in cabbages are needed. With the developments in genetics and molecular biology, it will be important to investigate the relationships between Brassica and TuMV at the molecular level, to understand the mechanism of resistance and to reveal new sources of resistance. This review has been prepared with the aim of bringing information about the genes and resistance mechanisms in Brassica species that have resistance to TuMV.
