Download or read book CRC Handbook of Viruses Infecting Legumes written by John R. Edwardson and published by CRC Press. This book was released on 2018-01-18 with total page 860 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interesting handbook discusses 145 plant viruses in 27 groups and 31 unclassified viruses in naturally infected legumes. The viruses were observed in field infections of 281 species in 64 genera of the Leguminosae. The book presents information regarding resistance sources and resistance-breeding, vectors, seed transmission, and host ranges. Measurements of virus properties are organized in tabular form for particle dimensions, serological relationships, nucleic acid percentages, sedimentation coefficients of particles and nucleic acids, molecular weights of nucleic acids and coat proteins, optical density, and buoyant density. Handbook of Viruses Infecting Legumes is unique in that it relates inclusion cytology to plant virus detection, identification, and classification. Light and electron micrographs illustrate morphology, location, and staining reactions of inclusions. Of the 27 groups that contain viruses infecting legumes in nature, inclusions are diagnostic at the group level in 15 of these groups. Plant breeders, diagnosticians, plant virologists, and students of plant virology will find this an indispensable guide to legume viruses.

This book was released on 1995 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed comparisons of the two sequences reveal significant differences in the organization and deduced amino acid sequences of the predicted major ORFs. Our observations suggest that while SBMV-B and SBMV-C are closely related, their classification as strains f the same virus may be questioned. Their capsid protein sequences show significant homology, supporting their close relatedness. Conversely, comparison of the differences in the amino acid sequences of the two suggests several structurally significant subsitutions which may have far reaching implications on the biology of the viruses and could delineate the two. However, SBMV-B and SBMV-C ORFs are either very similar (e.g., capsid protein gene: up to 90% at the N-terminus) or significantly different (ORF1:46%), depending on the region of the genome examined.

This book was released on 2019 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bean common mosaic virus (BCMV) is an important pathogen affecting common bean and other legumes. BCMV is an aphid-transmitted virus, which can also be seed-transmissible in common bean with efficiencies of up to 80%, depending on virus strain and bean cultivar. The virus belongs to the genus Potyvirus (family Potyviridae), having an approximately 10-kb single-stranded, positive-sense RNA genome. BCMV resistance in common bean is governed by one dominant (I) gene and four recessive (bc-u, bc-1, bc-2, and bc-3) genes which are deployed by breeders in different combinations to protect commercial bean cultivars against the virus. The dominant I gene confers extreme resistance or immunity against all strains of BCMV when the temperature stays below 30°C, and variable types of local and systemic necrosis when temperature exceeds 30°C. The bc-3 gene was identified as an eIF4E translation initiation factor gene mediating resistance through disruption of the interaction between this protein and the VPg protein of the virus. The mode of action of bc-1 and bc-2 in expression of BCMV resistance was unknown until this work. To investigate the possible role of both bc-1 and bc-2 genes in replication, cell-to-cell, and long distance movement of BCMV in P. vulgaris, we tested virus spread of eight BCMV isolates representing pathogroups I, IV, VI, VII, and VIII, in a set of bean differentials expressing different combinations of six resistance alleles including bc-u, bc-1, bc-12, bc-2, bc-22, and bc-3. The data suggest that bc-1 and bc-2 recessive resistance genes have no effect on the replication and cell-to-cell movement of BCMV, but affect systemic spread of BCMV in common bean. The BCMV resistance conferred by bc-1 and bc-2 and affecting systemic spread was found only partially effective when these two genes were expressed singly. The efficiency of the restriction of the systemic spread of the virus was greatly enhanced when the alleles of bc-1 and bc-2 genes were combined together.Beside common bean, there are other crop legumes that are susceptible to BCMV, such as peanut, soybean, and azuki bean. In this thesis, I described a new strain of BCMV from lima bean with distinct biological and molecular characteristics found in Honolulu, HI. This new BCMV strain, BCMV-A1, was able to partially overcome resistance to the virus conferred by bc-1 and bc-2 alleles in common bean, establishing an asymptomatic systemic infection in some common bean cultivars. Later, two BCMV isolates were found in commercial common bean samples in Idaho exhibiting 99% identity to BCMV-A1 in partial genome sequence. This new BCMV strain from lima bean, BCMV-A1, may present a threat for the common bean production.
