Bhendi yellow vein mosaic virus (BYVMV) or okra yellow vein mosaic (OYVMV) is a viral disease caused by monopartite Begomovirus affecting okra plants. [1] [2] It was first found in 1924 in Bombay, India, and Sri Lanka. [3] It is the major limitation of the production of okra. [4] This disease is transmitted by whitefly.

Taxonomy and genome

Bhendi yellow vein mosaic virus (BYVMV) is classified in the genus Begomovirus , family Geminiviridae . Like other begomoviruses, it possesses a circular, single-stranded DNA genome encapsidated in twinned icosahedral particles. Most isolates of BYVMV have a bipartite genome, designated DNA-A and DNA-B, each approximately 2.7 kilobases in length. [5] Phylogenetically, BYVMV groups with other Old World begomoviruses infecting Malvaceae plants such as cotton and hibiscus. [6]
