the effects of b, k10, and ar chromosomes on the resistance of maize to viral infection.studies were conducted to determine if accessory (b) chromosomes, the abnormal tenth (k10) chromosome or the aberrant ratio (ar) phenomenon of maize (zea mays l.) affect the resistance of the plants to viral infection. genetically similar stocks of maize with and without these elements were compared to determine what effect they would have on the plants response to brome mosaic virus (bmv), maize dwarf mosaic virus (mdmv), wheat streak mosaic virus (wsmv) and barley stripe mosaic virus (bsmv).-t ...197817248865
longidorus breviannulatus as a vector for brome mosaic virus. 198719290121
brome mosaic virus, good for an rna virologist's basic needs.abstract taxonomic relationship: type member of the bromovirus genus, family bromoviridae. a member of the alphavirus-like supergroup of positive-sense single-stranded rna viruses. physical properties: virions are nonenveloped icosahedrals made up of 180 coat protein subunits (fig. 1). the particles are 26 nm in diameter and contain 22% nucleic acid and 78% protein. the bmv genome is composed of three positive-sense, capped rnas: rna1 (3.2 kb), rna2 (2.9 kb), rna3 (2.1 kb) (fig. 2). viral protei ...200020572956
systemic virus-induced gene silencing allows functional characterization of maize genes during biotrophic interaction with ustilago maydis.infection of maize (zea mays) plants with the corn smut fungus ustilago maydis leads to the formation of large tumors on the stem, leaves and inflorescences. in this biotrophic interaction, plant defense responses are actively suppressed by the pathogen, and previous transcriptome analyses of infected maize plants showed massive and stage-specific changes in host gene expression during disease progression. to identify maize genes that are functionally involved in the interaction with u. maydis, ...201021039559
a foxtail mosaic virus vector for virus-induced gene silencing in maize.plant viruses have been widely used as vectors for foreign gene expression and virus-induced gene silencing (vigs). a limited number of viruses have been developed into viral vectors for the purposes of gene expression or vigs in monocotyledonous plants, and among these, the tripartite viruses brome mosaic virus and cucumber mosaic virus have been shown to induce vigs in maize (zea mays). we describe here a new dna-based vigs system derived from foxtail mosaic virus (fomv), a monopartite virus t ...201627208311
maize elongin c interacts with the viral genome-linked protein, vpg, of sugarcane mosaic virus and facilitates virus infection.the viral genome-linked protein, vpg, of potyviruses is involved in viral genome replication and translation. to determine host proteins that interact with sugarcane mosaic virus (scmv) vpg, a yeast two-hybrid screen was used and a maize (zea mays) elongin c (zmelc) protein was identified. zmelc transcript was observed in all maize organs, but most highly in leaves and pistil extracts, and zmelc was present in the cytoplasm and nucleus of maize cells in the presence or absence of scmv. zmelc exp ...201424954157
utilizing virus-induced gene silencing for the functional characterization of maize genes during infection with the fungal pathogen ustilago maydis.while in dicotyledonous plants virus-induced gene silencing (vigs) is well established to study plant-pathogen interaction, in monocots only few examples of efficient vigs have been reported so far. one of the available systems is based on the brome mosaic virus (bmv) which allows gene silencing in different cereals including barley (hordeum vulgare), wheat (triticum aestivum), and maize (zea mays).infection of maize plants by the corn smut fungus ustilago maydis leads to the formation of large ...201323386294
identification of differentially regulated maize proteins conditioning sugarcane mosaic virus systemic infection.sugarcane mosaic virus (scmv) is the most important cause of maize dwarf mosaic disease. to identify maize genes responsive to scmv infection and that may be involved in pathogenesis, a comparative proteomic analysis was performed using the first and second systemically infected leaves (termed 1 sl and 2 sl, respectively). seventy-one differentially expressed proteins were identified in 1 sl and 2 sl upon scmv infection. among them, eight proteins showed the same changing patterns in both 1 sl a ...201728627019
