In this work, the protective effect of ectoines against pH stress and high temperature has been investigated using an alkaline active xylanase from Bacillus halodurans as a model. The disaccharide, trehalose—a well-known stabiliser for biomolecules (Kaushik and Bhat 2003), has also been included in the study. The enzyme was selected as a model because it is efficiently active at high pH and is highly stable in the pH range of 5.5–10.5 at 50 °C.

The signaling properties of the gasotransmitter molecule hydrogen sulfide (H2S), which is endogenously generated in plant cells, are mainly observed during persulfidation, a protein post-translational modification (PTM) that affects redox-sensitive cysteine residues. There is growing experimental evidence that H2S in higher plants may function as a mechanism of response to environmental stress conditions.

Three separate experiments were carried out to assess combined effects of temperature and salinity and induced stress on blood variables of Tra catfish (Pangasianodon hypophthalmus) fingerlings. Some hematological parameters included Haemoglobin concentration, glucose and pH levels which were tested in different conditions. The experiment 1 aimed to test how blood variables change in different temperature (24, 28-30, 32 oC) and salinity (0, 6 and 12 ppt) while the experiment 2 induced catfish fingerlings to different stress time (5, 15 and 30 min.).

An immuno-homologue of maize Ca2+/calmodulin (CaM)dependent protein kinase with a molecular mass of 72 kDa was identified in pea. The pea kinase (PsCCaMK) was upregulated in roots in response to low temperature and increased salinity. Exogenous Ca2+ application increased the kinase level and the response was faster than that obtained following stress application. Low temperaturemediated, but not salinity-mediated stress kinase increase was inhibited by the application of EGTA and W7, a CaM inhibitor....

Environmental stress deleteriously affects every aspect of an ectotherm’s biological function. Frequent exposure of terrestrial insects to temperature variation has thus led to the evolution of protective biochemical and phy-siological mechanisms. However, the physiological mechanisms underlying the positive impact of fluctuating thermal regimes (FTRs) on the fitness and survival of cold-exposed insects have not been studied.

Groups of oysters (Crassostrea gigas) were exposed to 25C for 24 days (controls to 13 C) to explore the biochemical and molecular pathways affected by prolonged thermal stress. This temperature is 4C above the summer seawater temperature encountered in western Brittany, France where the animals were collected.
