The Role of Carbohydrates in Plant Resistance to Abiotic Stresses

Marina S. Krasavina, Natalia A. Burmistrova and Galina N. Raldugina

The role of various osmotically active compound accumulations in plant resistance to low and high temperatures, drought, and salinity is considered. Attention is paid to the specific features of definite compound accumulation under different stresses, their involvement in the maintenance of the redox balance in the cells, and their function as signaling molecules. Despite an accumulation of sugars and other metabolites to maintain the osmotic and redox equilibriums, this process is not systematically correlated with plant resistance. Carbohydrate accumulation in the leaves may be determined by the inhibition ...
