Activity and isoenzyme spectrum of peroxidases and dehydrins of some plant species, growing on the shores of lake Baikal, under abiotic stress

Termostability and optimal pH of weak-associated with plant cell wall and soluble peroxidases was shown to change in relation to natural conditions and season of year. Also the activity of peroxidase was variable during vegetation period. Dehydrine expression was followed by spike of peroxidase activity (and, a priori, an increase of hydrogen peroxide concentration)
