In natural ecosystems, plants compete for space, nutrients and light. The optically dense
canopies limit the penetration of photosynthetically active radiation and light often becomes …

Green plant photosystem II (PSII) is involved in the light reactions of photosynthesis, which
take place in the thylakoid membrane of the chloroplast. PSII is organized into large …

Phosphorus (P) is an essential macronutrient, and P deficiency limits plant productivity.
Recent work showed that P deficiency affects electron transport to photosystem I (PSI), but …

In plants, the photosynthetic machinery photosystem II (PSII) consists of a core complex
associated with variable numbers of light-harvesting complexes II (LHCIIs). The …

Photosynthetic light harvesting in plants is regulated by phosphorylation-driven state
transitions: functional redistributions of the major trimeric light-harvesting complex II (LHCII) …

The light-harvesting chlorophyll a/b binding proteins (LHCB) are perhaps the most abundant
membrane proteins in nature. It is reported here that the down-regulation or disruption of any …

State transitions are an important photosynthetic short-term response that allows energy
distribution balancing between photosystems I (PSI) and II (PSII). In plants when PSII is …

Oxygenic photoautotrophs require mechanisms for rapidly matching the level of chlorophyll
excited states from light harvesting with the rate of electron transport from water to carbon …

Six different xanthophyll cycles have been described in photosynthetic organisms. All of
them protect the photosynthetic apparatus from photodamage caused by light-induced …

Like any other area in science, both the scope and depth of our knowledge of plant and crop
physiology are rapidly expanding. Plant/crop physiologists are continuously making new …
