Indian peanut clump virus (IPCV)

This virus is found in India and Pakistan, where it causes the peanut clump disease of groundnuts. It can also infect cereals and other gramineous plants (Delfosse et al., 2002). Both in groundnuts and in cereals the disease can cause significant yield losses, in some cases between 30 and 60%. IPCV has a similar biology as the Peanut clump virus, occurring in Africa.

Groundnut plants infected by IPCV are stunted and form clumps of erect shoots, that do not spread along the ground like healthy plants. They produce few pods that are typically small and unmarketable. Young plants have chlorotic leaves with yellow lines, rings and/or faint mottling. The disease occurs in patches and is transmitted by the obligate root endoparasitic fungus Polymyxa graminis.
