2019年1月1日 · Several alleles at the pvr2 locus are known to control recessive resistance to Potato virus Y (PVY) in pepper. In this study, PVY resistant F 2 pepper lines were developed from local germplasm carrying recessive genes (pvr21 and …

2024年5月16日 · Potato virus Y (PVY) complex causes disease in many types of plants and crops including potato, tomato, pepper, tobacco, and eggplant. Symptoms range from mild yellow mottling on leaves to tuber necrosis (dying cells), which eventually kills the plant.

2013年3月11日 · PVY symptoms in tobacco, tomato and pepper often consist of mild mottling or mosaic (Fig. 1 c), although stunting and necrosis may be observed. In addition, in tobacco, PVY modifies the chemical composition of cured leaves, especially the nicotine content (Latorre et al., 1984), resulting in high economic losses.

Potato virus Y is a virus of the family Potyviridae, genus Potyvirus. It affects potatoes in two ways, reducing yield of the tubers and also compromising tuber quality. Some strains of PVY are also a concern for other solanaceous crops, such as pepper, tomato, tobacco and others.

2003年1月23日 · We show here that the pvr2 locus in pepper, conferring recessive resistance against strains of potato virus Y (PVY), corresponds to a eukaryotic initiation factor 4E (eIF4E) gene.

2014年10月11日 · Potato Virus Y (PVY) is a pathogen of economic importance in pepper and other major crop species in the family Solanaceae. Three major PVY strain groups: O, C, and N, have been distinguished on the basis of genome sequencing.

We performed a genome-wide association study of pepper (Capsicum annuum) tolerance to potato virus Y (PVY). For 254 pepper accessions, we estimated the tolerance to PVY as the coefficient of regression of the fresh weight (or height) of PVY-infected and mock-inoculated plants against within-plant vi …

2001年11月5日 · Potato virus Y (PVY) isolates originally coming from infected pepper plants, were biologically and genetically characterized, especially in comparison with PVY potato-isolates. Pepper PVY isolates could be differentiated from potato isolates in their host range, aphid transmission efficiencies, Mab serology, and genetic status.

2009年7月20日 · In this study, the genetic diversity of PVY infecting pepper was analysed in the regions of Bizerte and Cap Bon, the most important open-field pepper producing areas in Tunisia, with the aims of understanding the structure of PVY populations and estimating the impact of pepper genotype, notably the presence of a recessive resistance allele pvr2 ...

2019年1月1日 · Several alleles at the pvr2 locus are known to control recessive resistance to Potato virus Y (PVY) in pepper. In this study, PVY resistant F 2 pepper lines were developed from local germplasm carrying recessive genes (pvr21 and …
