Diagnosis and Characterization of Plant Viruses Using HTS to Support Virus Management and Tomato Breeding.

Viral diseases pose a significant threat to tomato crops ( L.), one of the world's most economically important vegetable crops. The limited genetic diversity of cultivated tomatoes contributes to their high susceptibility to viral infections.

Complete genome sequence of a novel polerovirus infecting chickpea (Cicer arietinum L.).

The complete genome sequence of a novel polerovirus identified in chickpea (C. arietinum L.) is presented.

Diversity and Distribution of Viruses Infecting Wild and Domesticated spp. in the Mesoamerican Center of Domestication.

Viruses are an important disease source for beans. In order to evaluate the impact of virus disease on biodiversity, we determined the identity and distribution of viruses infecting wild and domesticated spp. in the Mesoamerican Center of Domestication (MCD) and the western state of Nayarit, Mexico.

A new begomovirus isolated from a potyvirus-infected bean plant causes asymptomatic infections in bean and N. benthamiana.

In this work, a begomovirus isolated from a bean plant coinfected with the potyviruses bean common mosaic virus and bean common mosaic necrosis virus was characterized. The three viruses were detected by high-throughput sequencing and assembly of total small RNAs, but the begomovirus-related contigs did not allow precise identification. Molecular analysis based on standard DNA amplification techniques revealed the presence of a single bipartite virus, which is a novel begomovirus according to the current taxonomic criteria.

Complete genome sequence of a novel comovirus infecting common bean.

The complete genome sequence of a novel comovirus identified in Guanajuato, Mexico, in a common bean plant (Phaseolus vulgaris L.) coinfected with Phaseolus vulgaris alphaendornavirus 1 (PvEV-1) and Phaseolus vulgaris alphaendornavirus 2 (PvEV-2) is presented. According to the current ICTV taxonomic criteria, this comovirus corresponds to a new species, and the name "Phaseolus vulgaris severe mosaic virus" (PvSMV) is proposed for this virus based on the observed symptoms of "severe mosaic" syndrome caused by comoviruses in common bean.
