Red clover vein mosaic virus—A Novel Virus to New Zealand that is Widespread in Legumes

Red clover vein mosaic virus (RCVMV) is an important virus of leguminous crops that can cause devastating losses. During a routine survey of legumes conducted on the South Island of New Zealand, RCVMV was found in mixed infections in clover plants with Alfalfa mosaic virus and White clover mosaic virus. The full-length sequence of the New Zealand isolate RCVMV-NZ from clover shared 96% nucleotide sequence identity with a chickpea isolate previously described from Washington (United States). Targeted surveys of pea, faba bean, and pasture crops showed that RCVMV-NZ is widespread on the South Island in New Zealand. This isolate is causing mild if any symptoms on experimental hosts and naturally infected plants.
