Abstract: Chlorophyll degradation is closely related to crop production. Delayed chlorophyll degradation in crops increases photosynthetic capacity at late stages,leading to the increase of crop production. With the development of structural biology,genome sequencing and bioinformatics in recent years,the regulatory mechanism of plant chlorophyll degradation pathway has witnessed some great progresses;especially PAO(Pheide a oxygenase)pathway,the primary chlorophyll degradation pathway,has been largely elucidated. In this review,we summarized the advances on 3 aspects of chlorophyll degradation pathways,the regulatory mechanism and stay-green mutants,and we also discussed some future research directions,aim to supply idea for the crop breeding and efficient use of light in crop.

Key words: chlorophyll, degradation, stay-green, PAO pathway
