Membrane Phospholipid Phase Separations in Plants Adapted to or Acclimated to Different Thermal Regimes

Membrane phospholipid phase separations in plants adapted to or acclimated to different thermal regimes.

The phase separation temperatures of total leaf phospholipids from warm and cool climate plants were determined in order to explore the relationship of lipid physical properties to a species' thermal habitat. The separation temperatures were determined by measuring the fluorescence intensity and fluorescence polarization of liposomes labeled with the polyene fatty acid probe trans-parinaric aci...

Is fluid-phase endocytosis conserved in hepatocytes of species acclimated and adapted to different temperatures?

Our primary objective was to determine if rates of fluid-phase endocytosis (FPE) were conserved in hepatocytes from organisms acclimated and adapted to different temperatures. To this aim, the fluorescent dye Lucifer yellow was employed to measure FPE at different assay temperatures (AT) in hepatocytes from 5 degrees C- and 20 degrees C-acclimated trout, Oncorhynchus mykiss (at 5 and 20 degrees...

Thermal tolerance and oxygen consumption rates of the catfish Horabagrus brachysoma (Günther) acclimated to different temperatures

Disentangling population strategies of two cladocerans adapted to different ultraviolet regimes

Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life-history traits of two lineages of Daphnia pulex. The lineages differed in the UVR dose they had received at their place of origin from extremely high UVR stress a...

Morphophysiological and Biochemical Responses of Zinnia elegans to Different Irrigation Regimes in Symbiosis with Glomus mosseae

Water deficit conditions, in addition to reduced water uptake, result in a reduction in nutrient uptake, and consequently, a substantial reduction in growth parameters, yield and quality. Substrate inoculation with arbuscular mycorrhizal fungi (AMF) as an environmentally friendly biofertilizer is an important strategy to improve the growth parameters and quality of products in such conditions. ...
