Viruses_RHheadline bar picture of virusesOur study of plant viruses includes nucleotide sequencing of pathogenic isolates of the ilarvirus, *Prunus necrotic ringspot virus*, and introduction of pathogen-derived resistance into cherry. We have also sequenced and are studying the genome expression of *Maize rayado fino virus*, the smallest plant virus known to replicate in both its insect vector and plant host. In addition, we have completed cloning and sequence analysis of two potyviruses - the GDD isolate of *Bean yellow mosaic virus* - and the first complete nucleotide sequence of *Beet mosaic virus*. Isolates of *Prunus necrotic ringspot virus* causing mild to severe symptoms cluster into phylogenetically distinct groups based on sequence analysis of the coat protein gene.abstract picture of viruses Sugar beet infected with *Beet mosaic virus*. abstract
