Furthermore, this RGA family was also found in the potato genome, but the number of the RGAs was higher than in tomato.Īgrios G (1997) Plant pathology, 4th edn. Transient gene silencing indicated that a member of this RGA family is required for Ph- 3-mediated resistance to late blight in tomato. Each RGA showed high homology to the late blight R gene Rpi- vnt1.1 from Solanum venturii. Four of these genes are resistance gene analogs (RGAs) with a typical nucleotide-binding adaptor shared by APAF-1, R proteins, and CED-4 domain. Eight putative genes were found in the corresponding 74 kb region of the tomato Heinz1706 reference genome. Ph- 3 was mapped in a 0.5 cM interval between two markers, Indel_3 and P55. In this study, a high-resolution genetic map covering the Ph- 3 locus was constructed using an F 2 population of a cross between Solanum lycopersicum CLN2037B (containing Ph- 3) and S. It was previously assigned to the long arm of chromosome 9. The Ph- 3 gene from Solanum pimpinellifolium was introgressed into cultivated tomatoes and conferred broad-spectrum resistance to P. In contrast, less work has been conducted on tomato. In the past decades, many late blight resistance ( R) genes have been characterized in potato. Late blight, caused by the oomycete pathogen Phytophthora infestans (Mont.) de Bary, is a devastating disease for tomato and potato crops.
