Electron microscopy studies of spinach thylakoids have suggested that the lumen is a densely 1998-03-20 The TLP18.3 gene was found with a domain of unknown function (DUF477), a family of uncharacterized proteins. Arabidopsis thaliana thylakoid lumen 18.3 protein gene is up-regulated during dehydration. Expression of chloroplast-related DNA sequence in salt sensitive sunflower line by salt stress Ascorbate serves in the following roles in the thylakoid lumen: 1. It functions as a cofactor for violaxanthin–de-epoxidase (VDE), the enzyme involved in the formation of nonphotochemical quenching. Thus, it is necessary for photoprotection (Toth et al., 2013). 2. 2017-10-23 The electron transport chain moves protons across the thylakoid membrane into the lumen.

Nucleotide-Dependent Processes in the. Thylakoid Lumen of Plant Chloroplasts. thylakoid lumen of Arabidopsis thalianaManuscript (preprint) (Other academic) the thylakoid lumen from Arabidopsis thaliana deficient in AtCYP20-22007In: Abstract : In this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II Within the chloroplasts is an intricate membrane system, the thylakoid membrane, which is the site of light harvesting and photosynthetic electron transport. Assessment of the requirement for aquaporins in the thylakoid membrane of plant chloroplasts to sustain photosynthetic water oxidation.

The thylakoid membrane has a characteristic flat shape and is differentiated into appressed grana stacks and single non-appressed stroma-exposed lamellae. The inner surface of the thylakoid membrane encloses a narrow, continuous com-partment, the lumen (1, 2). Electron microscopy studies of spinach thylakoids have suggested that the lumen is a densely It has been known for a long time that the thylakoid lumen provides the environment for oxygen evolution, plastocyanin-mediated electron transfer, and photoprotection. More recently lumenal proteins have been revealed to play roles in numerous processes, most often linked with regulating thylakoid b … Tylakoider finns i kloroplaster i gröna växters blad och hos cyanobakterier och är platsen för fotosyntesens ljusreaktion.

When the molecule is moving from cytosol to the thylakoid lumen, then it must cross the two membranes of the chloroplast and thylakoid membrane. There is a total of three layers that are needed to be crossed while traveling from the cytoplasm to the thylakoid lumen.
