Dependence of groundnut rosette virus on its satellite RNA as well as on groundnut rosette assistor luteovirus for transmission by Aphis craccivora.

Abstract excerpt

Transmission of groundnut rosette virus (GRV) by Aphis craccivora is known to depend on the additional presence in the source plants of a luteovirus, groundnut rosette assistor virus (GRAV). Naturally occurring isolates of GRV contain a satellite RNA which is the main cause of rosette symptoms in groundnut, different variants of the satellite being responsible for the green and chlorotic forms of rosette. In...
