Chlorophylls are magnesium-tetrapyrrole molecules that play essential roles in
photosynthesis. All chlorophylls have similar five-membered ring structures, with variations …

Photosynthetic organisms require chlorophyll or bacteriochlorophyll for their light trapping
and energy transduction activities. The biosynthetic pathways of chlorophyll and …

Flowering plants (angiosperms) can grow at extreme altitudes, and have been observed
growing as high as 6,400 metres above sea level,; however, the molecular mechanisms that …

Rice (Oryza sativa L.) frequently suffers in late spring from severe damage due to cold
spells, which causes the block of chlorophyll biosynthesis during early rice seedling …

Higher plants produce four classes of tetrapyrroles, namely, chlorophyll (Chl), heme,
siroheme, and phytochromobilin. In plants, tetrapyrroles play essential roles in a wide range …

The Fourth Edition of the Handbook of Photosynthesis offers a unique and comprehensive
collection of topics in the field of photosynthesis, serving as an invaluable resource in this …

NADPH: protochlorophyllide oxidoreductase (POR) catalyzes photoreduction of
protochlorophyllide (Pchlide) to chlorophyllide in chlorophyll (Chl) synthesis, and is required …

An extraordinarily precise regulation of chlorophyll biosynthesis is essential for plant growth
and development. However, our knowledge on the complex regulatory mechanisms of …

Chloroplast development is usually regarded as proceeding from proplastids. However,
direct or indirect conversion pathways have been described in the literature, the latter …

Chlorophyll b is synthesized from chlorophyll a by chlorophyll a oxygenase. We have
identified two genes (OsCAO1 and OsCAO2) from the rice genome that are highly …
