摘　　要：Dear Editor, Photorespiration is an essential metabolic process in leaves that facilitates recovery of carbon lost by the oxygenase reaction of Rubisco and avoids the accumulation of the toxic product,2-phosphoglycolate (2PG) of this reaction (Bauwe et al.,2012).However,there is also evidence to suggest that photorespiration has a more complex role during normal growth than the mere detoxification of 2PG and the recovery of 3-phosphoglycerate (3PGA) (Bauwe et al.,2012).The current view is that photorespiration is an essential mechanism to maintain optimal photosynthesis,normal growth,and development of oxygenic photosynthetic organisms in an oxygen-containing environment (Bauwe et al.,2012). 关键词：呼吸酶活性代谢 RUBISCO 组织光呼吸生长期反应磷酸
