Molecular Heterogeneity of Lectins in Wheat Seedlings under the Action of Stevioside and Heavy Metals

Abstract

© 2018, Pleiades Publishing, Ltd. The effect of the diterpene glycoside stevioside and high concentrations of heavy metals on the molecular heterogeneity of lectins was studied in seedlings of Kazanskaya 560 winter wheat cultivar. Stevioside induced the emergence of a new 45-kDa lectin. Cultivation of wheat seedlings in CdSO4and ZnSO4solutions resulted in the emergence of the protein with Mr = 88 kDa. We detected the presence of both lectins in seedlings during combined treatment with stevioside and heavy metals.
