Rice tungro bacilliform virus Rice tungro bacilliform virus Rice tungro bacilliform virus (RTBV) is a plant pararetrovirus of the family Caulimoviridae. Tungro means 'degenerated growth' and was first observed in Philippines. Rice tungro bacilliform virus was first described by Saito in 1975. Galves (1968) purified the virus and reported that the particles are polyhedral with a diameter of 30-33 nanometers. The virus withstands temperatures below 63-degree Celsius for 10 minutes. The tungro virus is known to have at least two strains - S and M. The 'S' strain in these varieties produces conspicuous interveinal chlorosis, giving an appearance of yellow stripe and sometimes irregular
