Effect of eosin Y on the formation of local lesions and on the accumulation of callose in ‘Samsun NN’ tobacco and French bean leaves inoculated with tobacco mosaic virus

Abstract

When leaf-halves of ‘Samsun NN’ tobacco or bean plants were floated on a solution of 10–15 μM eosin Y after inoculation with tobacco mosaic virus (TMV) and kept at 20° C, local lesion formation was markedly diminished. There was also a decrease in the size of the lesions. Depending on the temperature very strong fluorescence due to callose formation was… (More)
