Abstract:

The immune and physiological responses of mud crab (Scylla paramamosain) under air exposure were studied. The results showed that air exposure increased plasma activities of AST, ALT, ALP. There was a significant increase in glucose (GLU) and malondialdehyde (MDA) levels after air exposure. The transcript levels of SOD, CAT, HSP90, HSP70, p53, and hypoxia-inducible factor-1 (HIF-1) were induced by air exposure. Furthermore, caspase-3 transcript significantly increased at 48 and 72 h, while it significantly decreased at 96 h and 120 h under air exposure. These results suggested that oxidative stress occurred in the prolonged period of air exposure. HIF-1 and p53 signaling pathways played an important role under air exposure.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
