Plants of Capsicum annuum cv. Magali R, resistant to Pepper yellow mosaic virus (PepYMV), which showed severe yellow mosaic, leaf malformation and stunting were observed during the 2003/04 growing season in Lins, São Paulo State, Brazil. Potyvirus-like particles observed in leaf sap from infected plants under the electron microscope reacted with an antiserum against PepYMV in PTA-ELISA. In addition to C. annuum cv. Magali R, this potyvirus also infected systemically the resistant C. annuum cv. Rubia R. The nucleotide sequence of part of the CP gene of this potyvirus shared 96-98% identity with that of other PepYMV isolates. The partial nucleotide sequence of the 3' NTR showed 94-96% identity with that of PepYMV. These data indicate that this potyvirus is a...

Bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the most serious diseases of rice in all major rice-growing areas of Thailand. The most effective approach to control BB is the use of resistant varieties which is economically feasible, an environmental-friendly control method and easy for farmers to handle. However, the selection pressure from the usage of resistant cultivars may result in mutation of the pathogen population to overcome the resistance genes. A feasible method to solve this problem is by pyramiding multiple resistance genes, which are board spectrum, into susceptible rice varieties. The aims of this research were to identify the effectiveness of board spectrum BB resistance genes and to better understand the...

Molecular identification and mapping of a novel stripe rust resistance gene in wheat resistance line CH5389
Provedor de dados: 65

ABSTRACT: Stripe rust, caused by Puccinia striiformis is one of the most destructive diseases of wheat worldwide. CH5389 is a wheat-Thinopyrum intermedium derived line conferring stripe rust resistance. Genetic analyses of seedlings of F2 populations and F2:3 families developed by crossing CH5389 and susceptible common wheat revealed that stripe rust resistance in CH5389 was controlled by a single dominant gene that was designated YrCH5389. Eight SSR and EST-PCR polymorphic markers on chromosome 3AL were identified in F2 population of CH5389/Taichung29. The YrCH5389 was flanked by EST marker BE405348 and SSR marker Xwmc388 on chromosome 3AL with genetic distances of 2.2 and 4.6 cM, respectively. Comparative genomic analysis demonstrated that the...
