Protochlorophyllide

The Arabidopsis mutant (FLU), unable to control biosynthesis of protochlorophyllide, glows red in the blue light.
The structure of monovinyl protochlorophyllide.

Protochlorophyllide, or monovinyl protochlorophyllide, is an immediate precursor of chlorophyll a that lacks the phytol side-chain of chlorophyll. Protochlorophyllide is highly fluorescent; mutants that accumulate it glow red if irradiated with blue light. In Angiosperms, the last step, conversion of protochlorophyllide to chlorophyll, is light-dependent, and such plants are pale (chlorotic) if grown in the darkness. Gymnosperms, algae, and photosynthetic bacteria have another, light-independent enzyme and grow green in the darkness as well.
