Journal of Biological Chemistry, 2010 A recently developed technique for dilution of the naturally high protein packing density in isolated grana membranes was applied to study the dependence of the light harvesting efficiency of photosystem (PS) II on macromolecular crowding.

Journal of Microscopy, EarlyView.Abstract Cryo‐Focused Ion Beam Scanning Electron Microscopy (cryoFIB‐SEM) using samples fixed by high‐pressure freezing uniquely enables high‐resolution cryo‐volume Electron Microscope (cvEM) images of cell ultrastructure to be obtained from whole cells and complex tissues in their near native state. As the freezing process also preserves fluorescence,

Journal of Phycology, EarlyView.Abstract Three novel taxa in the Coleofasciculales were observed in hot springs in Yellowstone National Park, Wyoming, United States, and in the Tabaconcito thermal springs on the Rio Tabacón in Costa Rica. Flavicapitulum vaporiphilum gen. et sp. nov. was located in a supported clade with Gracilinea and Marmoreocelis.

Uni‐site ATP synthesis in thylakoids
FEBS Letters, 1990 Uni‐site ATP synthesis was measured with thylakoids. The membrane‐bound ATP‐synthase, CF0F1 was brought into the active, reduced state by illumination in the presence of thioredoxin, dithiothreitol and phosphate. This enzyme contains two tightly bound ATP per CFoF1. ATP was released from the enzyme when ADP was added in substoichiometric amounts during

New Phytologist, EarlyView.Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions, including membrane remodeling during abiotic stress.

Complete genome structure of Gloeobacter violaceus PCC 7421, a cyanobacterium that lacks thylakoids.
DNA Research, 2003 The nucleotide sequence of the entire genome of a cyanobacterium Gloeobacter violaceus PCC 7421 was determined. The genome of G. violaceus was a single circular chromosome 4,659,019 bp long with an average GC content of 62%. No plasmid was detected.

Evolution of Thylakoid Structural Diversity
Annual Review of Cell and Developmental BiologyOxygenic photosynthesis evolved billions of years ago, becoming Earth's main source of biologically available carbon and atmospheric oxygen. Since then, phototrophic organisms have diversified from prokaryotic cyanobacteria into several distinct clades of eukaryotic algae and plants through endosymbiosis events.
