| description | For over a century, breeders have worked to develop tomato (<i>Solanum lycopersicum</i>) cultivars with resistance to Fusarium wilt (<i>Fol</i>) caused by the soilborne fungus <i>Fusarium oxysporum</i> f. sp. <i>lycopersici</i>. Host resistance is the most effective strategy for the management of this disease. For each of the three <i>Fol</i> races, resistance has been introgressed from wild tomato species, predominately in the form of R genes. The <i>I, I-2, I-3</i>, and <i>I-7</i> R genes have each been identified, as well as the corresponding Avr effectors in the fungus with the exception of <i>Avr7</i>. The mechanisms by which the R gene protein products recognize these effectors, however, has not been elucidated. Extensive genetic mapping, gene cloning, and genome sequencing efforts support the development of tightly-linked molecular markers, which greatly expedite tomato breeding and the development of elite, <i>Fol</i> resistant cultivars. These resources also provide important tools for pyramiding resistance genes and should support the durability of host resistance. |
