Variation Within and Between Vitis spp. for Foliar Resistance to the Downy Mildew Pathogen Plasmopara viticola
Vitis vinifera grapevines are highly susceptible to downy mildew caused by the host-specific oomycete Plasmopara viticola. In humid climates like New York, where the unchecked pathogen will defoliate vines and destroy young fruit clusters, growers depend upon multiple fungicide applications for disease management. However, management of P. viticola by fungicides is tenuous, because the pathogen...
متن کاملNucleotide sequence and genomic organization of melon necrotic spot virus.
Cloned cDNA copies of the genomic RNA of melon necrotic spot virus (MNSV) have been sequenced and the sizes and locations of predicted viral proteins have been deduced. The genome consists of at least 4262 nucleotides and the positive strand contains three to five open reading frames (ORFs) which may be expressed. The 5' proximal ORF encodes a 29K protein (p29) and terminates with an amber codo...
متن کاملGenetic Investigation of Resistance to Beet Necrotic Yellow Vein Virus
Management of rhizomania includes planting in cool soils, proper irrigation and soil fumigation with methyl bromide. However, breeding for resistance to BNYW is the most critical aspect of rhizomania control In this study, the inheritance of resistance to beet necrotic yellow vein virus (BNYW) in B. vulgaris subsp. maritima. wild beet (WB) accession WB42 was investigated. Crosses between resist...
متن کاملFunctional analysis of the five melon necrotic spot virus genome-encoded proteins.
Function of the melon necrotic spot virus (MNSV) genome-encoded proteins (p29, p89, p7A, p7B and p42) has been studied. Protein-expression mutants of an infectious, full-length cDNA clone of a Spanish MNSV-Al isolate and a recombinant green fluorescent protein (GFP)-expressing virus were used in infection bioassays on melon plants. Results revealed that p29 and p89 are both essential for virus ...
متن کاملMolecular epidemiology of white spot syndrome virus within Vietnam.
White spot syndrome virus (WSSV), the sole member of the virus family Nimaviridae, is a large double-stranded DNA virus that infects shrimp and other crustaceans. By alignment of three completely sequenced isolates originating from Taiwan (WSSV-TW), China (WSSV-CN) and Thailand (WSSV-TH), the variable loci in the genome were mapped. The variation suggests the spread of WSSV from a common ancest...
