Outline of Final Research Achievements |
①We confirmed that Potato Cyst Nematode (PCN)-resistant tomato cultivars in Japan contained the HeroA gene, whereas susceptible cultivars did not. ②PCN-resistant tomato cultivars are identical to Tabacco Cyst Nematode (TCN)-resistant tomato cultivars. ③When segregated progenies from the selfing of resistant cultivar (Doctor-K) were inoculated with PCN, the progenies segregated into 20 resistant and five susceptible plants, fitting the 3 : 1 ratio expected for single-gene inheritance (χ2=0.61, P=0.56). ④Microarray analyses were performed to investigate the transcriptome profiles in the incompatible and compatible interactions at 3 and 7 days postinoculation (dpi).The PR1(P4,P6) transcript increased to exceptionally high level at 3 dpi in the cyst nematode-infected resistant plants compared to the uninoculated controls. ⑤We elucidated the effective of cyst nematode-resistant tomato cultivars in reducing the population of TCN in greenhouse traials.
