Light-harvesting protein LHCB5 is one of the three minor antenna proteins (LHCB4-6) that connect core (C) photosystem II (PSII) with strongly (S) and moderately (M) bound peripheral trimeric antennae (LHCIIs), forming a dimeric PSII supercomplex known as C2S2M2. Plants lacking LHCB4 LHCB6 do not form C2S2M2, indicating these are crucial for C2S2M2 assembly. However, studies on antisense asLhcb5 plants suggest this may apply to LHCB5. Using mild clear-native PAGE (CN-PAGE) electron microscopy...
The largest stable photosystem II (PSII) supercomplex in land plants (C2S2M2) consists of a core complex dimer (C2), two strongly (S2) and moderately (M2) bound light-harvesting protein (LHCB) trimers attached to C2 via monomeric antenna proteins LHCB4-6. Recently, we have shown that LHCB3 LHCB6, presumably essential for plants, are missing Norway spruce (Picea abies), which results unique structure its C2S2M2 supercomplex. Here, performed structure-function characterization PSII...
Photosystem II (PSII) complexes are organized into large supercomplexes with variable amounts of light-harvesting proteins (Lhcb). A typical PSII supercomplex in plants is formed by four trimers Lhcb (LHCII trimers), which bound to the core dimer via monomeric antenna proteins. However, architecture Norway spruce[Picea abies (L.) Karst.] different, most likely due a lack two proteins, Lhcb6 and Lhcb3. Interestingly, spruce shares similar structural features its counterpart green alga...
Cyclic electron transport around photosystem I (PSI) is essential for the protection of photosynthetic apparatus in plants under diverse light conditions. This process primarily mediated by Proton Gradient Regulation 5 protein/Proton 5-like phenotype 1 protein (PGR5/PGRL1) and NADH dehydrogenase-like complex (NDH). In angiosperms, NDH interacts with two PSI complexes through distinct monomeric antennae, LHCA5 LHCA6, which crucial its higher stability variable interaction represents an...
In the context of global climate change and increasing need to study plant response drought, there is a demand for easily, rapidly, remotely measurable parameters that sensitively reflect leaf water status. Parameters with this potential include those derived from spectral reflectance (R) chlorophyll fluorescence. As each these methods probes completely different characteristics, their sensitivity loss may differ in species and/or under circumstances, making it difficult choose most...
During 2013-2015, a monitoring study was carried out on the migration, abundance, and infectivity of Cacopsylla picta C. melanoneura in apple orchards that were under different types management. The presence symptomatic non-symptomatic trees infected by 'Candidatus Phytoplasma mali' studied. It demonstrated psyllid vectors is same without regard to growth management applied orchard. potential risk phytoplasma spreading an integrated lower due side-effects insecticides psyllids. Their shorter...
