Stevioside-induced molecular heterogeneity and lectin activity at low positive temperatures

Abstract

This article describes the results of a study on the effect of pre-sowing treatment of Triticum aestivum L. seeds with stevioside (10-8 M) for 24 h on the activity and molecular heterogeneity of lectins in seedlings at low positive temperatures. Phytolectins take part in a wide range of physiological processes in plants, regulating not only growth, but also increasing resistance to salinity, heavy metals, and temperature stress. In this regard, the study of changes in the activity and heterogeneity of these molecules in the search for new regulators of plant growth and development is urgent. The observed stevioside-induced increase in the activity of lectins bound to the cell wall and changes in their qualitative and quantitative composition against the background of temperature stress may indicate an increase in the adaptive potential of wheat plants.
