Comments "Cowpea chlorotic mottle virus (CCMV Family:Bromo-viridae genus:Bromovirus) is a spherical plant virus that causes an important disease in legumes worldwide. CCMV contains a segmented positive single-stranded RNA genome [1]. The genome is divided into RNA 1 (3.1 kb), RNA 2 (2.7 kb), and RNA 3 (2.1 kb). Monocistronic RNA 1 and RNA 2 encode non-structural proteins (1a and 2a proteins) that are responsible for virus replication [2,3]. The 5' region of the dicistronic RNA 3 encodes the non-structural 3a protein necessary for viral movement (MP, 32-kDa protein) which is responsible for the systemic spread of the virus. The 3' region encodes a structural protein (coat protein, CP, 20-kDa protein) translated from a subgenomic RNA 4 that is transcribed from the complementary strand of RNA 3 and is required for virus encapsidation [4]."
