light harvestingnonphotochemical fluorescence quenchingproton gradientzeaxanthinNon-photochemical quenching (NPQ) of chlorophyll fluorescence is the process by which excess light energy is harmlessly dissipated within the photosynthetic membrane. The fastest component of NPQ, known as energy-dependent quenching ...
In plants and green algae, light-harvesting complexes (LHCs) are a large family of chlorophyll binding proteins functioning as antennae, collecting solar photons and transferring the absorbed energy to the photosynthetic reaction centers, where light to chemical energy conversion begins. Although LHCs ...
The implication of a plastid-derived factor in the transcriptional control of nuclear genes encoding the light-harvesting chlorophyll a/b protein In carotenoid-deficient albina mutants of barley and in barley plants treated with the herbicide Norflurazon the light-dependent accumulation of the mRNA f....
Photosystem I (PSI) is a major player in the light reactions of photosynthesis. In higher plants, it consists of a core complex and four external antennae, Lhca1–4 forming the PSI–light-harvesting complex I (LHCI) supercomplex. The protein and pigment composition as well as the spectroscopi...
Light-Harvesting Complex II (LHCII) is largely responsible for light absorption and excitation energy transfer in plants in light-limiting conditions, while in high-light it participates in photoprotection. It is generally believed that LHCII can change its function by switching between different confo...
In subject area: Chemistry The light-harvesting complex proteins (LHC1) are small (20–30 kDa) hydrophobic membrane proteins that bind chlorophyll and carotenoid molecules and thus function as light energy collectors, funneling the excitation energy to PS I. Four different LHC1 proteins are known ...
