Characterization of a cold-responsive dehydrin promoter
Dehydrins are type II LEA proteins induced in many plants during drought, low temperature, and high salinity to confer stress tolerance. AtERD14 is an Arabidopsis thaliana dehydrin that functions in part of the cold stress pathway. AtERD14 has chaperone-like capabilities that allow it to bind and …

Physiological study of cold acclimation in Rhododendron sp. with emphasis on role of dehydrins
… study we established the significance of 25 kDa dehydrin accumulation during cold acclimation (CA) in a wide array of Rhododendron species. These species (24 in total) belong to two diverse subgenera, Hymenanthes and Rhododendron, native to diverse latitudes and altitudes. The dehydrin of …

Identification of clone x rootstock effects on cold hardiness and relevant dehydrins changes in Cabernet franc (Vitis vinifera L.)
… research also looks at the protein expression of dehydrins which may impact cold hardiness. Four clone × rootstock combinations of Cabernet franc (214 × 101-14, 327 × 101-14, 327 × 3309, and 327 × Riparia Gloire) were assessed over two dormant seasons in 2018-19 and 2019-20. Buds were sampled …

Characterisation of two desiccation-linked dehydrins from Xerophyta humilis
… during dehydration. This study characterized two dehydrins that were expressed during dehydration in the desiccation tolerant plant, Xerophyta humilis. From a transcriptome analyses on X. humilis, cDNA for the two dehydrins were obtained. These sequences were first analysed using various in silico …

Physiological and genetic mechanism(s) of cold acclimation in Rhododendron
… were independent of non-acclimated FT. A 25-kDa dehydrin correlated with LFT differences among cold-acclimated F2 segregants. Moreover, its expression increased as LFT increased with both chronological age and developmental phase-change of wild and cultivated plants. The presence or absence of …

Gene expression associated with drought tolerance in Xerophyta viscosa Baker
… (50%). XVDH exhibited significant identity to dehydrin proteins from Arabidopsis thaliana (45%) and Pisum sativum (43%) at the amino acid level. It encodes a glycine-rich protein (27kDa) which is largely hydrophilic and contains a hydrophobic segment at the C-terminus. XVLEC showed 28% identity …

Analysis of maturation-specific genes in soybean seeds: Gene structure, desiccation induction and abscisic acid responsiveness
… proteins and also in the cotton LEA and barley dehydrin proteins. The N-termini of MAT proteins also contains a short 7-amino acid stretch which might be related to the tissue-specificity expression or activity of these proteins. Possible roles of MAT proteins in seed maturation processes are …

PHYSIOLOGICAL CHARACTERIZATION ON SEED AGING OF SIX NATIVE SHRUB SPECIES
… The electrolyte conductivity, as well as seed dehydrin protein expression, is strongly correlated with the seed vigour, which can be used as seed quality assessment methods in seed longevity predicting. A loss of membrane integrity occurred during the accelerated seed aging processes, as …

Physiological and Molecular Dissection of Salinity Tolerance in Arabidopsis and Maize and Nitrogen Uptake in Wheat
… with the dominant expression of downstream dehydrins. Furthermore, this study revealed that the prt6 mutation enhances ethylene and brassinosteroid responses, resulting in restricted Na+ accumulation in roots and shoots as well as increased expression of dehydrin genes such as RD29A and …

Molecular and physiological study of water-deficit stress on selected Eragrostis species
… studied any further. Nin-44 was identified as a dehydrin-like gene with approximately 99 % identity to seven water-deficit stress responsive genes on a section of about 60 bp near the 3' end. As its sequence was found to represent a partial insert size, two forward and reverse primers were …
