LEA proteins during water stress: not just for plants anymore.
Late embryogenesis abundant (LEA) proteins are extremely hydrophilic proteins that were first identified in land plants. Intracellular accumulation is tightly correlated with acquisition of desiccation tolerance, and data support their capacity to stabilize other proteins and membranes during drying, especially in the presence of sugars like trehalose. Exciting reports now show that LEA protein...
متن کاملLEA proteins prevent protein aggregation due to water stress.
LEA (late embryogenesis abundant) proteins in both plants and animals are associated with tolerance to water stress resulting from desiccation and cold shock. However, although various functions of LEA proteins have been proposed, their precise role has not been defined. Recent bioinformatics studies suggest that LEA proteins might behave as molecular chaperones, and the current study was under...
متن کاملStructure of tobacco genes encoding pathogenesis-related proteins from the PR-1 group.
Infection of Samsun NN tobacco with tobacco mosaic virus (TMV) was found to induce the synthesis of mRNA encoding a basic protein with a 67% amino acid sequence homology to the known acidic pathogenesis-related (PR) proteins 1a, 1b and 1c. By Southern blot hybridization it was shown that the tobacco genome contains at least eight genes for acidic PR-1 proteins and a similar number of genes enco...
متن کاملGenomic and evolutionary insights into genes encoding proteins with single amino acid repeats.
Mutations causing expansion of amino acid repeats are responsible for 19 hereditary disorders. Repeats in several other proteins also show length variations. These observations prompted us to identify single amino acid repeat-containing proteins (SARPs) in humans and to understand their functional and evolutionary significance. We identified 8812 SARPs containing 17 146 repeat domains, each har...
متن کاملIsolation and characterization of a drought-induced soybean cDNA encoding a D95 family late-embryogenesis-abundant protein.
LEA proteins represent severa1 families of proteins that accumulate to high levels in maturing seeds. The expression of these proteins is under developmental control, but they may also be expressed in dissected embryos exposed to exogenous ABA (Hughes and Galau, 1991). Many Leu genes are also expressed in vegetative tissues exposed to exogenous ABA as well as water, osmotic, and low-temperature...
