Functional characterisation of LEA proteins from bdelloid rotifers
… remains largely elusive. Recently, two group 3 LEA (late embryogenesis abundant) proteins, ArLEA1A and ArLEA1B, have been identified in the desiccation-induced gene set in the bdelloid species Adineta ricciae that are hypothesised to protect these animals by preventing protein aggregation and …

Characterization of two, desiccation linked, Group 1 LEA proteins from the resurrection plant Xerophyta humilis
… show expression of Late Embryogenesis Abundant (LEA) proteins associated with desiccation tolerance. However, the precise role of these proteins has not been described. This study was undertaken to investigate expression, structure and function of XhLEA1-4S1 and XhLEA1-1S2, Group 1 LEA proteins …

Biostabilization of Lipid Bilayers: Dealing with Water Stress in Embryos of Artemia franciscana
… found in embryos of Artemia franciscana. Two LEA proteins were used: AfrLEA2 and AfrLEA3m. AfrLEA3m was experimentally demonstrated to reside in the matrix. Two detergents were used to differentially solubilize the outer and inner membranes of mitochondria isolated from A. franciscana. Release …

Isolation and characterisation of a LEA-like protein from yeast (Saccharomyces cerevisiae)
LEA proteins are plant proteins that are characteristically hydrophilic and soluble at elevated temperature. The consistent correlation between desiccation tolerance in orthodox seed tissue and an accumulation of LEA proteins suggests that these proteins play an important role in protecting cells …

Characterisation of two desiccation-linked dehydrins from Xerophyta humilis
… observed to express Late Embryogenesis Abundant (LEA) proteins as protective mechanisms. However, despite two decades of research, little is understood about their physiological functions and this has led to extensive nomenclature, with a large amount of redundancy. The primary reason for this …

The functional analysis of XhLEA3-2 - a LEA_4 from the resurrection plant, Xerophyta humilis
… of several Late Embryogenesis Abundant (LEA) genes. The protein products of these genes, called LEA proteins, are known to be correlated with abiotic stress tolerance in plants, invertebrates and microorganisms. However, the precise molecular mode(s) of action of LEA proteins are still …

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 …

Molecular characterisation of the "LEAome" in the resurrection plant Xerophyta humilis (Baker)
… have shown that Late Embryogenesis Abundant (LEA) proteins are expressed upon the onset of desiccation and are therefore inferred to be associated with the desiccation tolerance response. To date, despite some 25 years of research on these proteins, there is still very little understanding of …

Regulation of desiccation tolerance in Xerophyta seedlings and leaves
… trait of poikilochlorophylly as seen in mature leaves. The X. humilis desiccation transcriptome comprising 76,768 distinct gene clusters was successfully assembled from sequencing samples at five relative water contents (100%, 80%, 60%, 40% and 5%) to identify the networks activated in response …

A Molecular and Phylogenetic Analysis of Cryobiosis in Nematodes of the Genus Panagrolaimus
… adaptations may include the synthesis of proteins such as antifreeze proteins or cryoprotectants such as trehalose, the elimination of ice nucleators, and the expression of stress associated proteins (such as molecular chaperones, antioxidants, late embryogenesis abundant (LEA) proteins). …
