Summary Light‐induced structural changes in thylakoid membranes have been reported for decades, with conflicting data regarding their shrinkage or expansion during dark–light transitions. Understanding these dynamics is important for both fundamental photosynthesis research and agricultural applications. This research investigated the temporal sequence

Metabolic and molecular events occurring during chromoplast biogenesis [PDF]
Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,

Uncoupling of Spinach Thylakoids by Gramine
Abstract The indol alkaloid gramine inhibited photophosphorylation, Pi-ATP exchange reaction and proton gradient, and enhanced electron transport in spinach thylakoids with I 50 around 0.2 mᴍ. It thus behaves as a typical uncoupler of photophosphorylation.

Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

The protein import apparatus of chloroplasts [PDF]
Routing of cytosolically synthesized precursor proteins into chloroplasts is a specific process which involves a multitude of soluble and membrane components.

Protein kinases of the thylakoid membrane.
The claim of Racker and co-workers (Lin, Z. F., Lucero, H. A., and Racker, E. (1982) J. Biol. Chem. 257, 12153-12156 and Lucero, H. A., Lin, Z. F., and Racker, E. (1982) J. Biol. Chem. 257, 12157-12160) that two protein kinases, designated CPK1 (25 kDa) and CPK2 (38 kDa), are present in spinach thylakoid membranes was investigated in light of results ...

Summary The Chl d‐containing cyanobacterium, Acaryochloris marina MBIC11017, is constitutively adapted to far‐red light (FRL). However, it occasionally encounters white light (WL) in its natural habitat. Using biochemical and spectroscopic techniques, we investigated how this organism acclimates to WL and analysed the excitation energy trapping ...

Combined enhancement of ascorbic acid, β‐carotene and zeaxanthin in gene‐edited lettuce
Summary Lettuce is widely grown and consumed but provides lower nutritional value compared to other leafy greens, particularly in the essential vitamins A and C. To address this, major control points in carotenoid and ascorbic acid (AsA) production were targeted using a viral‐based CRISPR/Cas9 system in the commercial lettuce cultivar ‘Noga’.

Cellular and thylakoid-membrane glycolipids of Chlamydomonas reinhardtii 137+.
The glycolipids of the green alga Chlamydomonas reinhardtii 137+ have been quantitated in the phototrophically-cultured cell and in its thylakoid membrane. Three lipids, the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol

On the Non-Oxygenic Origins of Thylakoids [PDF]
Thylakoid membranes are the site of oxygenic photosynthesis, one of the most important biochemical processes on earth. The ancestral state of these membranes is represented today in Gloeobacterales, where they are lacking and photosynthesis instead takes place in the cytoplasmic membrane.
