The structure of intact and active Photosystem II from Arabidopsis thaliana at 2.44 Å resolution
New Phytologist, EarlyView.Summary Photosystem II (PS II) is a large membrane‐bound protein complex that catalyses light‐driven water oxidation in plants and cyanobacteria. The structure of PS II is well studied in cyanobacteria; however, there are very few PS II structures from plants.

PhytoMilk: Effects of botanical composition and harvest system of legume/grass silage on fatty acid, α-tocopherol and β-carotene concentration in organic forage and milk [PDF]
, 2010 Red clover and high proportion of forage in dairy cow diet increases the concentration of bioactive substances in milk, e.g. unsaturated fatty acids and antioxidants. In the present experiment twenty-four Swedish Red dairy cows were fed three silages in

New Phytologist, EarlyView.Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

New Phytologist, EarlyView.Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Functional divergence of LhcSR and PsbS in zeaxanthin‐mediated non‐photochemical quenching
New Phytologist, EarlyView.Summary To protect photosystem II from excess light, non‐photochemical quenching (NPQ) dissipates excess energy as heat. NPQ relies on trigger proteins, LhcSR in algae and PsbS in vascular plants, and the light‐regulated xanthophyll cycle, which interconverts violaxanthin and zeaxanthin through the opposite activities of violaxanthin de‐epoxidase and ...

Management of Surgical Margins in the Excision of Oral Leukoplakia: A Scoping Review
Oral Diseases, EarlyView.ABSTRACT Objective To map the literature on management of surgical margins for oral leukoplakia (OL) and proliferative verrucous leukoplakia (PVL). Methods Searches were performed in five electronic databases and gray literature. Studies involving patients undergoing any type of surgical excision of OL or PVL were included.
