What are the symptoms of yellow vein mosaic virus?

What causes yellow vein mosaic?

This disease is caused by a complex consisting of the monopartite begomovirus Bhendi yellow vein mosaic virus (BYVMV, family: Geminiviridae) and a small satellite DNA beta component. BYVMV can systemically infect bhendi upon agroinoculation but produces only mild leaf curling in this host.

Who has discovered yellow vein mosaic virus for the first time?

35.3. 3 Bhendi yellow vein mosaic virus. BYVMV was first reported by Kulkarni (1924) from Mumbai, India. This virus has been reported in Bangladesh, India, Pakistan, Thailand, Sri Lanka, and China on okra plants (Kulkarni, 1924; Tsai et al., 2013).

How is yellow mosaic virus transmitted?

The virus is transmitted by over 20 species of aphids (e.g., the pea, green peach, and bean aphids).
