Technical Abstract: A strain of red clover vein mosaic virus (RCVMV-ChP) was isolated from chickpea (Cicer arietinum L.) grown in the Palouse region of Washington State. Symptoms on chickpea included severe stunting, mosaic, proliferation of axillary buds, and malformation of leaves and branches. Flower and pod formation were severely reduced. The host range was similar to that of the type strain (ATCC RCVMV pv110). However, the viruses could be readily differentiated by mechanical inoculation to Chenopodium amaranticolor and C. quinoa. RCVMV pv110 produced chlorotic local lesions on the inoculated leaves, while RCMV-ChP produced small (0.5 mm), necrotic local lesions. The RCVMV-ChP virion coat protein was ca. 25,000 Daltons when determined by SDS-PAGE. The virion nucleic acid consisted of a single species ssRNA with a molecular weight of 7.05 x 10**6. Studies by ELISA indicated no serological relationship between RCVMV-ChP and isolates of pea streak and alfalfa latent carlaviruses. This is the first report of RCVMV occurring in chickpea.
