General Information

General Information Comment Organism
physiological function strong MGD1 suppression causes a 36% loss of monogalactosyldiacylglycerol in etiolated seedlings, together with a 41% decrease in total protochlorophyllide content. The loss of monogalactosyldiacylglycerol perturbes etioplast membrane structures and impaires the formation of the photoactive protochlorophyllide-light-dependent NADPH:protochlorophyllide oxidoreductase-NADPH complex and its oligomerization, without affecting light-dependent NADPH:protochlorophyllide oxidoreductase accumulation. The MGD1 suppression also impairs the formation of protochlorophyllide from protoporphyrin IX via multiple enzymatic reactions in etioplast membranes. Monogalactosyldiacylglycerol biosynthesis at an early germination stage is particularly important for protochlorophyllide accumulation Arabidopsis thaliana
