自20世纪70年代发现与光呼吸途径相关的能量损失以来，光呼吸一直是作物改良的目标。然而，最近的研究强调了光呼吸作为核酮糖-1，5-二磷酸（RuBP）氧化产物的再循环途径及其与初级代谢的密切联系的重要性。然而，减少光呼吸损失的替代补救途径的安装在拟南芥（拟南芥）导致增强的生长和生物量。这种方法也可能在野外条件下证明是有用的，在未来的大气中含有较高的CO2浓度与高温或有限的水相结合。
Photorespiration has been a target for crop improvement ever since the energy losses associated with this pathway were identified in the 1970s. However, recent research highlights the importance of photorespiration as a recycling pathway for the products of ribulose-1, 5-bisphosphate (RuBP) oxygenation and its intimate interconnection with primary metabolism. Nevertheless, reducing photorespiratory losses by installation of alternative salvage pathways in Arabidopsis (Arabidopsis thaliana) resulted in enhanced growth and biomass. Such approaches will probably also prove useful under field conditions, and in a future atmosphere containing higher CO2 concentrations combined with high temperature or limiting water.
