A shared mucosal gut microbiota signature in primary sclerosing cholangitis before and after liver transplantation

open access: yesHepatology, EarlyView., 2022
In this study of the gut mucosal microbiota in primary sclerosing cholangitis (PSC), we found consistent microbiota features associated with PSC and recurrent PSC, PSC with inflammatory bowel disease and a persistent gut dysbiosis after liver transplantation Abstract Background and Aims Several characteristic features of the fecal microbiota have been ...

Phototropin 1 and 2 Influence Photosynthesis, UV-C Induced Photooxidative Stress Responses, and Cell Death

open access: yesCells, 2021
Phototropins are plasma membrane-associated photoreceptors of blue light and UV-A/B radiation. The Arabidopsis thaliana genome encodes two phototropins, PHOT1 and PHOT2, that mediate phototropism, chloroplast positioning, and stomatal opening.

Tocopherol and plastoquinone synthesis in spinach chloroplasts subfractions [PDF]

open access: yes, 1980
Subfractions isolated from intact purified spinach chloroplasts are able to prenylate the aromatic moiety of -tocopherol and plastoquinone-9 precursors. The biosynthesis of -tocopherol and plastoquinone-9 is a compartmentalized process.

The Intracellular Distribution of Folate Derivatives in Pea Leaves

open access: yesPteridines, 2003
After hydrolysis of polyglutamate derivatives, leaf extracts of pea (Pisum sativum L.) seedlings were examined for individual folates using high performance liquid chromatography and microbiological assays employing Lactobacillus rhamnosus and ...

Fertility recovery of anther-derived haploid plants in Cape gooseberry (Physalis peruviana L.)

open access: yesAgronomía Colombiana, 2018
The cape gooseberry (Physalis peruviana L.) is one of the most important Colombian exotic fruits. Chromosome doubling of anther-derived plants is a key factor in the application of double haploid technology for the genetic improvement of crops.

Cadmium Disrupts Subcellular Organelles, Including Chloroplasts, Resulting in Melatonin Induction in Plants

open access: yesMolecules, 2017
Cadmium is a well-known elicitor of melatonin synthesis in plants, including rice. However, the mechanisms by which cadmium induces melatonin induction remain elusive.

Chloroplast to chromoplast transition in tomato fruit: spectral confocalmicroscopy analyses of carotenoids and chlorophylls in isolated plastids and time-lapse recording on intact live tissue [PDF]

open access: yes, 2011
During evolution, chromoplasts have emerged as plastid structures which accumulate pigments to facilitate flower pollination and seed dispersal of fleshy fruit.

Biosynthesis of galactolipids by enzyme preparations from spinach leaves

open access: yesJournal of Lipid Research, 1969
The pH optimum for galactolipid synthesis from UDP-galactose by spinach chloroplasts is 7.2 in Tris-HCl or phosphate buffer. The products include sterol glycosides, trigalactosyl diglyceride (tentatively identified), digalactosyl diglyceride, and ...

Chloroplast envelope protein encoded by chloroplast genome

open access: yesFEBS Letters, 1993
The gene product of an open reading frame of chloroplast genome, ORF 231 in pea, was immunochemically detected in chloroplast and etioplast envelopes. This is the first protein of a Chloroplast Envelope Membrane encoded by a chloroplast genome. It was named CEM A and the gene, cem A.

The formation of homogentisate in the biosynthesis of tocopherol and plastoquinone in spinach chloroplasts [PDF]

open access: yes, 1982
Homogentisate is the precursor in the biosynthesis of -tocopherol and plastoquinone-9 in chloroplasts. It is formed of 4-hydroxyphenylpyruvate of the shikimate pathway by the 4-hydroxyphenylpyruvate dioxygenase.
