Dehydrins belong to a protein family whose expression may be induced or enhanced by developmental process and environmental stresses that lead to cell dehydration. A dehydrin gene named OesDHN was isolated and characterized from oleaster (Olea europaea L. subsp. europaea, var. sylvestris), the wild form of olive. To elucidate the contribution of OesDHN in the development of drought tolerance, i...
The nucleotide sequence of a full-length cDNA, the deduced amino acid sequence, and the regulation of expression of a cold acclimation-specific gene, cas18, in cell suspension cultures of a freezing-tolerant cultivar of alfalfa (Medicago falcata cv Anik) have been determined. The deduced polypeptide, CAS18, is relatively small (17.6 kD), is highly hydrophilic, is rich in glycine and threonine, ...
Expression of the wheat dehydrin gene Cor410b is induced several fold above its non-stressed levels upon exposure to stresses such as cold, drought and wounding. Deletion analysis of the TdCor410b promoter revealed a single functional C-repeat (CRT) element. Seven transcription factors (TFs) were shown to bind to this CRT element using yeast one-hybrid screens of wheat and barley cDNA libraries...
Development of winter hardiness in trees is a two-stage process involving sequential perception of distinct environmental cues, short-day (SD) photoperiod and low temperature (LT). We have shown that both SD and LT are recognized by leaves of silver birch (Betula pendula cv Roth) leading to increased freezing tolerance, and thus leaves can be used as an experimental model to study the physiolog...
Dehydrins, also known as the late embryogenesis abundant (LEA) D-11 family of proteins (Close et al., 1993, and refs. therein), generally accumulate in plants in response to water deficit, embryo desiccation, cold temperature, reduction in externa1 osmotic potential, or application of ABA. Over 40 examples of deduced amino acid sequences of higher plant dehydrins have been published to date, an...
Abstract Soil salinisation is an important factor limiting the cultivation and distribution of Prunus mume . Therefore, identifying regulation mechanism salt tolerance P. will promote its molecular breeding. In this study, garden tree species ‘Meiren’ was investigated, with a soil NaCl content (w/w) 0.3%. Photosynthetic gas exchange parameters, relative electrical conductivity, malondialdehyde,...
