Abstract

Ethylene promotes the expression of one of the most common symptoms of ageing: the suppression of protein and nucleic acid synthesis. Artificial inhibition or promotion of protein synthesis results in an increased or decreased evolution of ethylene, respectively. In hosts with viral local lesions caused by TMV and TNV, a certain degree of enhanced ethylene production was demonstrated before the appearance of local lesions. However, the mass of the evolution of ethylene occurred at the very beginning of tissue necrosis. In systemic infections the rate of ethylene production remained unchanged. In another local virus infection (bean yellow mosaic virus on Tetragonia expansa), causing chlorotic spots instead of necroses, the evolution of ethylene also increased. It is concluded that the increased production of ethylene is connected to local tissue senescence caused by local virus infections but not necessarily to local necroses.
