Abstract

Incidence of Southern bean mosaic virus (SBMV) on common bean (Phaseolus vulgaris L.) in Aragua State, Venezuela, and partial molecular characterization of a viral isolate.

Abstract

In surveys of common bean (Phaseolus vulgaris L.), 819 samples from plants showing virus-like symptoms were collected throughout the main growing fields in Aragua state, Venezuela. The samples were tested for Southern bean mosaic virus (SBMV) using indirect enzyme linked immunosorbent assay (ELISA). More than 30% of the tested plants were infected with the virus. Sequence analyses targeting the 5′-terminal region of a virus isolate showed 90-97% similarity to corresponding sequences of other SBMV isolates deposited in the GenBank database. This is the first study on the incidence of SBMV in Venezuela and on the partial molecular characterization of a Venezuelan isolate of SBMV.
