摘要：

Plastid genes encoding light-independent protochlorophyllide oxidoreductase (LIPOR) subunits were isolated from cryptophyte algae, the first example of such genes in plastids of secondary endosymbiotic origin. The presence of functional and nonfunctional copies of LIPOR genes in cryptophytes suggests that light-independent chlorophyll biosynthesis is a nonessential pathway in these organisms.
