Induction of Glutaredoxin Expression in Response to Desiccation Stress in the Foliar Nematode Aphelenchoides fragariae.
Desiccation tolerance plays an important role in the overwinter survival of the foliar nematode Aphelenchoides fragariae. Survival rates of A. fragariae were compared with those of the anhydrobiotic soil-dwelling nematode Aphelenchus avenae after desiccation (90% RH), cold (4°C) and osmotic (500 mM sucrose) stress treatments. A. fragariae formed aggregates during desiccation and showed higher s...
متن کاملTransition from natively unfolded to folded state induced by desiccation in an anhydrobiotic nematode protein.
Late embryogenesis abundant (LEA) proteins are associated with desiccation tolerance in resurrection plants and in plant seeds, and the recent discovery of a dehydration-induced Group 3 LEA-like gene in the nematode Aphelenchus avenae suggests a similar association in anhydrobiotic animals. Despite their importance, little is known about the structure of Group 3 LEA proteins, although computer ...
متن کاملAge specific sensitivity of the nematode Aphelenchus avenae to mercury toxicity.
Although one of the ultimate goals of ecotoxicology is to predict the effects of chemical substances and compounds on whole communities and ecosystems, it is generally accepted by ecotoxicologists that single-species toxicity tests may provide an adequate first step toward the ecological risk assessment of pollutants in soil and water. Consequently, several toxicity tests (ASTM 1993) have been ...
متن کاملMAPK phosphorylation is implicated in the adaptation to desiccation stress in nematodes.
Some nematodes can survive almost complete desiccation by entering an ametabolic state called anhydrobiosis requiring the accumulation of protective molecules such as trehalose and LEA proteins. However, it is not known how anhydrobiotic organisms sense and regulate the response to water loss. Mitogen-activated protein kinases (MAPKs) are highly conserved signalling proteins that regulate adapt...
متن کاملWater loss and morphological changes during desiccation of the anhydrobiotic nematode Ditylenchus dipsaci
Ditylenchus dipsaci is an anhydrobiotic nematode which can withstand direct exposure to extreme desiccation. Water loss has been determined gravimetrically and morphological changes quantified by light microscopy. Water loss occurs in two distinct phases, with a permeability slump 2 min after the onset of desiccation. The permeability slump remains after treatment with sodium azide or carbon di...
