Complementary action of two independent dominant genes in Columbia soybean for resistance to Soybean mosaic virus.
A stem-tip necrosis disease was observed in the soybean [Glycine max (L.) Merr.] cultivar Columbia and its derivative OX686 when infected with a necrosis-causing strain of Soybean mosaic virus (SMV) in Canada. A dominant gene named Rsv3 was found in OX686 for the necrotic reaction. In the present research we have found that Columbia is resistant to all known SMV strains G1-G7, except G4. Geneti...
متن کاملSimultaneous Mutations in Multi-Viral Proteins Are Required for Soybean mosaic virus to Gain Virulence on Soybean Genotypes Carrying Different R Genes
BACKGROUND Genetic resistance is the most effective and sustainable approach to the control of plant pathogens that are a major constraint to agriculture worldwide. In soybean, three dominant R genes, i.e., Rsv1, Rsv3 and Rsv4, have been identified and deployed against Soybean mosaic virus (SMV) with strain-specificities. Molecular identification of virulent determinants of SMV on these resista...
متن کاملGenetics of resistance to two strains of soybean mosaic virus in differential soybean genotypes.
There are seven pathotypes of soybean mosaic virus (SMV) representing seven strain groups (G1-G7) in the United States. Soybean genotypes [Glycine max (L.) Merr.] may exhibit resistant (R), susceptible (S), or necrotic (N) reactions upon interacting with different SMV strains. This research was conducted to investigate whether reactions to two SMV strains are controlled by the same gene or by s...
متن کاملGenetic analysis of resistance to soybean mosaic virus in j05 soybean.
Soybean cultivar J05 was identified to be resistant to the most virulent strain of soybean mosaic virus (SMV) in northeastern China. However, the reaction of J05 to SMV strains in the United States of America is unknown, and genetic information is needed to utilize this germplasm in a breeding program. The objectives of this study were to determine the reaction of J05 to all US strains of SMV (...
متن کاملChapter Five Mechanisms of the Soybean Rsv3 Gene for Resistance to Soybean mosaic virus
Resistance to Soybean mosaic virus (SMV; Genus Potyvirus; Family Potyviridae) in soybean (Glycine max [L.] Merr.) is controlled by single dominant genes at three distinct loci, Rsv1, Rsv3 and Rsv4. The mechanisms of resistance at the Rsv3 locus were investigated in Harosoy and the Williams isoline L29 by tracking virus replication and movement. Two other cultivars with two genes for resistance ...
