Abstract

Abstract: Although R genes have been showed significantly age-related resistance（ARR），the mechanism of QTLs involved in this resistance is still unknown. With susceptible material Solanum lycopersicum‘LA2818’，resistant material S. lycopersicum‘CLN2037B’and S. pimpinellifolium‘L3708’as control，the age-related resistance of QTL were studied. Except susceptible control LA2818，6-leaf stage and 9-leaf stage plants of S. habrochaites accessions LA2099，LA1033 and LA1777，which contain QTL also showed age-related resistance，were more resistant significantly to late blight disease than 3-leaf stage plants. Thus there is a common defense mechanism in tomato against Phytophthora infestans through ARR. Meanwhile，ethylene，salicylic acid and jasmonic acid synthesis or missing mutants and Virus Induced Gene Silencing（VIGS）technology were combined to study the resistant mechanisms of 6-leaf stage plants harboring Ph-3 gene. The results showed that ethylene and salicylic acid but not jasmonic acid wereinvolved in the resistance to late blight mediated by Ph-3 gene.

Key words: tomato, Phytophthora infestans, age-related resistance, QTL, pathway mutant, VIGS
