What is Dehydrin gene?
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.
What are dehydrin proteins?
Dehydrins are considered stress proteins involved in the formation of plants’ protective reactions to dehydration. They can also be considered as hydrophilins.
What is the function of k segment in structure of dehydrin gene?
Our data provide evidence that the K-segment plays a significant role in WZY2 function. This segment is critical for maintaining bacterial growth, enhancing LDH activity, and preventing protein aggregation during temperature stress.
What are protective functions of Dehydrins on cell structure?
simple (III) Dehydrins can non-specifically bind proteins and membranes, which can protect the function and structure of the protein or membrane from damage caused by environmental stresses. simple (Iv) Dehydrins can bind DNA, which may repair or protect the DNA from damage caused by environmental stresses.
What is the difference between DHN and dehydrin related proteins?
These proteins are considered dehydrin-like or dehydrin-related. They are poorly defined, in that these dehydrin-like proteins are similar to DHNs, but are unfit to be classified as DHNs for varying reasons. They are found to be similar in that they respond to some or all of the same environmental stresses that induce DHN production.
Is the K-segment of dehydrin conserved in DHNs?
Many DHNs contain at least one copy of a consensus 15-amino acid sequence called the K-segment, EKKGIMDKIKEKLPG. However, an inspection of a range of other reported dehydrin sequences shows that its conservation is not absolute.
What is dehydrin and why is it important?
The protein has since been referred to as dehydrin and has been the identified as the genetic basis of drought tolerance in plants. However, the first direct genetic evidence of dehydrin playing a role in cellular protection during osmotic shock was not observed until 2005, in the moss, Physcomitrella patens.
What is the role of dehydrins in the pathogenesis of fungal infections?
Dehydrins have been reported to confer resistance against fungal infections and over-expression of dehydrins provide protection under abiotic and biotic stress conditions. ^ Puhakainen T, Hess MW, Mäkelä P, Svensson J, Heino P, Palva ET (March 2004).
