title: The significance of alpha-amylase under anoxia stress in tolerant rhizomes (Acorus calamus L.) and non-tolerant tubers (Solanum tuberosum l., var. Désirée).
abstract: Rhizomes of Acorus calamus L. were able to maintain a functional alpha-amylase under anoxia, whereas a steep decrease in the enzyme protein content and activity took place in potato tubers. The stress-induced control in tubers occurred on the translational level. It is suggested that this decrease is one of the key factors with regard to anoxia intolerance.
