Chlorophyll Synthesis in a Deetiolated (det340) Mutant of Arabidopsis without NADPH-Protochlorophyllide (PChlide) Oxidoreductase (POR) A and Photoactive PChlide-F655.

The Plant cell

Lebedev N, Van Cleve B, Armstrong G, Apel K.

Plant Cell. 1995 Dec;7(12):2081-2090. doi: 10.1105/tpc.7.12.2081.

Chlorophyll (Chl) synthesis in Arabidopsis is controlled by two light-dependent NADPH-protochlorophyllide (PChlide) oxidoreductases (PORs), one (POR A) that is active transiently in etiolated seedlings at the beginning of illumination and another (POR B) that also operates in green plants....

Two NADPH:Protochlorophyllide Oxidoreductases in Barley: Evidence for the Selective Disappearance of PORA during the Light-Induced Greening of Etiolated Seedlings.

The Plant cell

Reinbothe S, Reinbothe C, Holtorf H, Apel K.
PMID: 12242364
Plant Cell. 1995 Nov;7(11):1933-1940. doi: 10.1105/tpc.7.11.1933.

Chlorophyll synthesis in barley is controlled by two different light-dependent NADPH:protochlorophyllide oxidoreductases, termed PORA and PORB. PORA is present abundantly in etioplasts but selectively disappears soon after the beginning of illumination. This negative light effect is mediated simultaneously at...
