Abstract |
|---|
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 non-functional copies of LIPOR genes in cryptophytes suggests that light-independent chlorophyll biosynthesis is a non-essential pathway in these organisms.
