摘　　要：Despite the presence of about 21%O2 in the atmosphere,organs of plants and mammals are inevitably subject to lower O2 tensions(pO2)due to high O2 demand in metabolic active cells and limited O2 transport efficiency.In humans,for example,the p O2 decreases from the ambient 21%(160 mm Hg)of the inhaled air to 2%-9%in the internal organs(Brahimi-Horn and Pouyssegur,2007).To cope with this limited oxygen supply,aerobic organisms have developed a variety of adaptive responses at cellular,tissue,and organismal levels(Bailey-Serres et al.,2012).Although low O2 tensions are the normal conditions for organs,the ambient 21%O2 is usually referred to as normoxia and the lower internal concentrations as hypoxia(van Dongen and Licausi,2015).
