The crystal structure of the sobemovirus Ryegrass mottle virus (RGMoV) has been determined at 2.9 A resolution. The coat protein has a canonical jellyroll beta-sandwich fold. In comparison to other sobemoviruses the RGMoV coat protein is missing several residues in two of the loop regions. The first loop contributes to contacts between subunits around the quasi-threefold symmetry axis. The alte...
The structure of cucumber mosaic virus (CMV; strain Fny) has been determined to a 3.2-A resolution using X-ray crystallography. Despite the fact that CMV has only 19% capsid protein sequence identity (34% similarity) to cowpea chlorotic mottle virus (CCMV), the core structures of these two members of the Bromoviridae family are highly homologous. As suggested by a previous low-resolution struct...
Pathogens have evolved various strategies to overcome host immunity for successful infection. Maize chlorotic mottle virus (MCMV) can cause lethal necrosis in maize (Zea mays) when it coinfects with a the Potyviridae family. However, MCMV pathogenicity determinant remains largely unknown. Here we show that P31 protein of is important viral accumulation and essential symptom development. Ectopic...
Fourteen isolates of Rice yellow mottle virus (RYMV) were selected as representative of the genetic variability of the virus in Africa from a total set of 320 isolates serologically typed or partially sequenced. The 14 isolates were fully sequenced and analyzed together with two previously reported sequences. RYMV had a genomic organization similar to that of Cocksfoot mottle sobemovirus. The a...
Viruses are most frequently discovered because they cause disease. To expand knowledge of plant-associated viruses beyond these narrow constraints, non-cultivated plants of the Tallgrass Prairie of the United States were systematically surveyed for evidence of viruses. This report discusses putative viruses of the family Secoviridae identified by the survey. Sequence analysis suggests the prese...
