Cellular responses to sudden environmental stresses or physiological changes provide living organisms with the opportunity for final survival and further development. Therefore, it is an important topic to understand protective mechanisms against environmental stresses from the viewpoint of gene and protein networks. We propose two coupled nonlinear stochastic dynamic models to reconstruct stre...

Honeybees are essential pollinators that play a crucial role in maintaining the global ecosystem and food security. However, recent years, honeybee populations have been declining rapidly due to combination of factors, including environmental stresses. Environmental stresses such as habitat loss, pesticide use, climate change, disease some major affect survival health colonies. These can honeyb...

fennel (foeniculum vulgare mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds andmedicinal uses. as the wild and cultivated plants are influenced by environmental stresses, the effects of salt (25, 50 and 75 mm nacl), nitrogen and iron deficiency (0 n, 0.5 n of hoagland’s solution, 0 fe and 0.5 fe ofhoagland’s solution), 2°c cold (2, 3 and 4 h) and drought (3, 5...

the main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. we were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. if such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. in addi...

The PHD-finger family has been demonstrated to be involved in regulating plant growth and development. However, little information is given for its role in environmental stress responses. Here, we identified a total of 59 PHD family genes in the rice genome. These OsPHDs genes were located on eleven chromosomes and synteny analysis only revealed nine duplicated pairs within the rice PHD family....

BACKGROUND Fundamental questions in evolutionary genetics, including the possible advantage of sexual reproduction, depend critically on the effects of deleterious mutations on fitness. Limited existing experimental evidence suggests that, on average, such effects tend to be aggravated under environmental stresses, consistent with the perception that stress diminishes the organism's ability to ...

Ascorbic acid (AA) is present in all eukaryotes including animals and plants and lack completely in prokaryotes with exception of cyanobactaria. Today, AA has gained significant place in plant science, mainly due to its properties (antioxidant and cellular reductant etc.), and multifunctional roles in plant growth, development, and regulation of large spectrum of plant defense mechanisms agains...

Rotor cage faults as broken rotor bars, increased bars resistance and end-ring faults can be caused by thermal stresses, due to overload, overheating and thus mechanical stresses, magnetic stresses and dynamic stresses due to shaft torques. Environmental stresses as contamination or abrasion also contributes to the rotor cage faults. The rotor cage faults can also lead to the shaft vibration an...
