Abstract: Abiotic stresses with a dehydration component (drought, salt, and freezing) involve,
as a common feature, increased numbers of inactive proteins – denatured, aggregated or
oxidatively damaged. Maintaining proteins in their functional conformation, preventing
aggregation of non-native proteins, refolding of denatured proteins to their native
conformation and removal of non-functional and potentially harmful polypeptides are all
vital for cell survival under dehydration stress. To achieve this, plants respond to drought
by synthesis of protective proteins such as dehydrins and chaperones and by degradation
of irreversibly damaged proteins by proteases. Here we review the important cellular
functions of dehydrins, chaperones, proteases and protease inhibitors, together with their
role in the response to drought, that make them potential biochemical markers for
assessing drought tolerance.
