Antifreeze proteins in the primary urine of larvae of the beetle Dendroides canadensis.
To avoid freezing while overwintering beneath the bark of fallen trees, Dendroides canadensis (Coleoptera: Pyrochroidae) larvae produce a family of antifreeze proteins (DAFPs) that are transcribed in specific tissues and have specific compartmental fates. DAFPs and associated thermal hysteresis activity (THA) have been shown previously in hemolymph and midgut fluid, but the presence of DAFPs ha...
متن کاملArginine, a key residue for the enhancing ability of an antifreeze protein of the beetle Dendroides canadensis.
Antifreeze proteins (AFPs) can produce a difference between the nonequilibrium freezing point and the melting point, termed thermal hysteresis (TH). The TH activity of an antifreeze protein (AFP) depends on the specific AFP and its concentration as well as the presence of cosolutes including low molecular mass solutes and/or proteins. We recently identified series of carboxylates and polyols as...
متن کاملFactors contributing to seasonal increases in inoculative freezing resistance in overwintering fire-colored beetle larvae dendroides canadensis
The insects and microarthropods that vary seasonally in susceptibility to cross-cuticular inoculation by external ice (inoculative freezing) represent a phylogenetically diverse group; however, few studies have explored possible mechanisms experimentally. This study documents seasonally variable inoculative freezing resistance in Dendroides canadensis beetle larvae and combines immunofluorescen...
متن کاملSanguinartia canadensis. Atributos médicos Medical Attributes of Sanguinaria canadensis - Bloodroot
Sanguinaria canadensis L., commonly known as bloodroot, red puccoon, Indian paint, redroot, pauson, or tetterwort, is found throughout most of North America east of the Rocky Mountains (Reed 1999). This herbaceous perennial is a member of the Papaveraceae (poppy family) (Reed 1999). It reaches a maximum of ten inches in height, has basal leaves that can be as wide as eight inches, and a white a...
متن کاملElodea canadensis Michx
This study aims to determine the changes in quantities of chlorophyll a and chlorophyll b in various lead concentrations. The main parts of Elodea canadensis have been subjected to lead concentrations, such as 0.1, 0.5, 1, 5, 10, 20, 50 and 100 mg L, with periods of 24, 48, 72, 120, 168 and 216 hours. Chlorophyll a and b quantities were measured in control plants and lead concentrations of 5, 1...
