Abstract:
Mg chelatase is the key enzyme of chlorophyll biosynthesis that catalyzes the insertion of Mg2+ into protoporphyrin IX. It is essential for photosynthesis and development of photoautotrophs species. This review focused on the regulation of Mg chelatase acitivity and the role of Mg chelatase in other pathways, such as plastid- to-nucleus retrograde signaling, abscisic acid signaling and sugar catabolism. Moreover, this review also provided prospect for future research in studying Mg chelatase.Key words: Mg chelatase; activity regulation; plastid-to-nucleus retrograde signaling; abscisic acid signaling
