| Eggplant is not only an important vegetable and economic crop in the world, but also the fourth largest Solanaceae crop just following potato, tomato and pepper. Bacterial wilt caused by Ralstonia solanacearum Smith is an important devastating disease in the eggplant industry. Scholars at home and abroad have been committed to the selection, evaluation and innovation of eggplant germplasm resources against bacterial wilt, genetic mapping, molecular marker development, discovery of functional genes, application of resistance breeding. The molecular mechanism of eggplant’s resistance to bacterial wilt is one of the hotspots and difficulties in plant disease resistance research in the world. This article summarizes the researches on the main pathotypes of bacterial wilt, cell biological mechanisms of eggplant resistance to bacterial wilt, germplasm resource screening, QTL mapping and molecular marker development, isolation and identification of disease resistance genes and their functional studies, and the strategies for genes mining of eggplant’s resistance to bacterial wilt based on multi-omics analysis. In addition, the current situation of the study on eggplant bacterial wilt are described systematically. The research and application of germplasm resource innovation, gene mining, gene editing and molecular breeding with cultivated eggplant as the resistance source is proposed with the improvement of multi-omics data of eggplant genome, re-sequencing and transcriptome and the development of emerging molecular biotechniques, with a view to providing a reference for further revealing the molecular mechanism of eggplant’s resistance to bacterial wilt and
solving the problem of bacterial wilt resistance by genetic engineering. |
