DOI: 10.1038/s41467-020-16644-4
Abstract: Many regulatory and signaling proteins have multiple modification sites. In bacterial chemotaxis, each chemoreceptor has multiple methylation sites that are responsible for adaptation. However, whether the ordering of the multisite methylation process affects adaptation remains… read more here.

DOI: 10.1093/gbe/evy233
Abstract: Abstract Although Tibetans and Sherpa present several physiological adjustments evolved to cope with selective pressures imposed by the high-altitude environment, especially hypobaric hypoxia, few selective sweeps at a limited number of hypoxia related genes were… read more here.

DOI: 10.1093/nsr/nwae284
Abstract: ABSTRACT It remains debatable how many genes and how various the mechanisms are behind human adaptation to extreme environments, such as high altitudes. Despite extensive studies on Tibetans, Andeans and Ethiopians, new insights are expected… read more here.

DOI: 10.1111/1749-4877.12710
Abstract: The harsh environment in the Tibetan plateau, the highest place in the world, poses thermoregulatory challenges and hypoxic stress to animals. The impacts of plateau environment on animal physiology and reproduction include external factors such… read more here.

DOI: 10.1111/1749-4877.12996
Abstract: Exposure to a hypoxic environment at high altitudes imposes severe pressure on animals living there, which utilize substantial cardiovascular and respiratory responses to meet the physiological challenge of oxygen requirement. These responses may result from… read more here.

DOI: 10.3389/fpls.2023.1125324
Abstract: Global warming causes great thermal stress to macroalgae and those species that can adapt to it are thought to be better able to cope with warmer oceans. Gracilaria bailinae, a macroalgae with high economic and… read more here.
