    Role of Dehydrins in Plant Stress Response

  • Original language description

    Dehydrins are LEA-II proteins defined by a presence of at least one copy of a lysine-rich sequence, a so-called K-segment, in their molecule. Based on the presence of conserved motifs named Y-segment (a tyrosine-rich region at the N-terminus), S-segment (a stretch of serine residues) and K-segment (a lysine-rich motif at the C-terminus), dehydrins can be classified into five structural groups Kn, SKn, KnS, YxSKn, and YxKn. Plants usually encode several dehydrin genes belonging to different structural groups and revealing different expression patterns under stress. Dehydrins are hydrophilic proteins with chaperone functions under dehydration stresses including drought, osmotic stress, salinity, freezing, wounding, and others. In this chapter, dehydrin molecular structure is discussed with respect to their biological functions (chaperons, cryoprotective, antifreeze, ion-binding, ROS-scavenging functions). Studies dealing with dehydrin transcript expression or protein accumulation with respect to plant abiotic stress tolerance under low-temperatures (cold and frost), drought, salinity and osmotic stress, heavy metal stress, and mechanical wounding are reviewed. Finally, possibilities of utilizing dehydrins for improvement of plant (crop) stress tolerance are discussed based upon physiological studies using both wild-type plants as well as transformants with enhanced dehydrin transcript expression (dehydrin protein accumulation).
