与低海拔地区相比,生活在海拔地区的生物体暴露于恒定的缺氧状态。最近的一项研究表明,开花植物通过分子氧(O2)传感的自然变化适应高海拔,高海拔种群表现出增加的O2敏感性,以平衡生理和代谢输出。这一发现表明,尽管植物和动物的缺氧信号通路存在差异,但真核生物界的海拔适应机制是趋同的。
Organisms living at elevation are exposed to a constant state of hypoxia compared to those at low altitude. A recent study has shown that flowering plants acclimatize to high altitude through natural variation in molecular oxygen (O2) sensing, with high-altitude populations exhibiting increased O2sensitivity to balance physiological and metabolic outputs. This finding demonstrates convergent mechanisms for altitude adaptation across eukaryotic kingdoms despite differences in the hypoxia-signalling pathways of plants and animals.
