Plants regularly face adverse growth conditions, such as drought, salinity, chilling, freezing, and high temperatures. These stresses can delay growth and development, reduce productivity, and, in extreme cases, cause plant death. Plant stress responses are dynamic and involve complex cross-talk between different regulatory levels, including adjustment of metabolism and gene expression for phys...

The behavioural patterns and their circadian rhythms may be adaptive to the peculiar environmental conditions of subtropical brackish waters where Bathygobius soporator Valenciennes, 1837 live. Adult fish were caught at the southern Brazilian coast from mangrove rivers and rocky shores in a bay, where temperature and water salinity vary during the day and through the year. Observation on the be...

junglerice, c4 plant and thermo-live of poaceae family, is one of the most serious grass weed in the tropics and subtropics. to determine methods for breaking dormancy, characterizing cardinal temperatures and investigating the effect of salinity and drought on junglerice seeds germination four separate experiments were conducted in the laboratory. results showed that the junglerice seed dorman...

Plants exposed to certain abiotic stress conditions tend to produce the amino acid proline, which acts as an active osmolyte, a metal chelator, an antioxidant, and a signaling molecule. There is increasing evidence that proline accumulates in plants due to a wide range of abiotic stress, in particular high soil salinity and drought. Therefore, proline content is often used as a marker-assisted ...

it has been known for years that microbial surface active agents have a wide range of applications not only in oil spill environment but also in many industries. their properties including: (i) changing surface active phenomena, such as lowering of surface and interfacial tensions, (ii) wetting and penetrating actions, (iii) spreading, (iv) hydrophylicity and hydrophobicity actions, (v) microbi...

in many studies, the medicinal properties and impact of blond plantain on mechanisms of human physical activities has been proven. salinity is an important abiotic stresses with detrimental effects on seed germination. an experiment was conducted to study germination characteristics of blond plantain under water and salinity stress conditions at different temperatures. the experiment was conduc...

plant growth is greatly influenced by environmental stresses including water deficit, salinity and extreme temperatures. hence, the identification of genes especially regulatory ones whose expression enables plants to adapt to or to tolerate these abiotic stresses, is very essential. myb proteins are a superfamily of transcription factors that play regulatory roles in developmental processes an...

In his book Civilization and Climate, Ellsworth Huntington (1876–1947) noted1 that “Almost any American or European who has travelled or resided within the tropics will confess that he has occasionally flown into a passion, and perhaps used physical violence, under circumstances which at home would merely have made him vexed.” This begs the question — why is there no violent conflict when sever...

Responses to moderate and extreme salinity change were investigated in White Sea Littorina saxatilis of different genetically determined shell colour morphs in order to test a hypothesis about physiological selection as a driving force of the change of phenotypic structure of this species along a salinity gradient in White Sea estuaries. Some of the studied physiological responses did not diffe...
