Senescence is a genetically regulated process that involves decomposition of cellular structures and distribution of the products of this degradation to other plant parts. Reactions involving reactive oxygen species are the intrinsic features of these processes and their role in senescence is suggested. The malfunction of protection against destruction induced by reactive oxygen species could be the starting point of senescence. This article reviews biochemical changes during senescence in relation to reactive oxygen species and changes in antioxidant protection.
