It’s transmitted by whitefly (Bemisia tabaci). Viruses contain bipartite genome DNA-A DNA-B. The DNA-A components encoded a replication associated protein that is vital for viral DNA replication, the coat protein (CP) and transcription activator protein that controls late gene expression. The DNA-B component encodes a movement protein (MP), both of which are crucial for systemic infection of plants. Symptoms of the disease are yellowing of veins,...
