It has frequently been observed that starch accumulates in plant tissues after virus infection. In pea plants infected with red clover mottle comovirus, strain 'O', virus replicates in the inoculated leaves and at the shoot apex where it induces lethal top necrosis. Concomitant with the onset of top necrosis, starch accumulates in the intervening leaves which remain substantially virus-free, This pattern of starch accumulation can be mimicked by removal of the apex in uninfected plants. We conclude that in this plant-virus interaction starch accumulation is an indirect consequence of virus infection associated with the removal of the physiological sink for photosynthate.
