AtRsmD Is Required for Chloroplast Development and Chloroplast Function in Arabidopsis thaliana

Frontiers in Plant Science, 2022
AtRsmD was recently demonstrated to be a chloroplast 16S rRNA methyltransferase (MTase) for the m2G915 modification in Arabidopsis. Here, its function of AtRsmD for chloroplast development and photosynthesis was further analyzed.

Exogenous melatonin improved photosynthetic efficiency of photosystem II by reversible phosphorylation of thylakoid proteins in wheat under osmotic stress

Frontiers in Plant Science, 2022
It has been well demonstrated that melatonin plays an important protective role in photosynthesis of plants under various environmental stresses, while the detailed mechanisms by which melatonin protects photosystem II (PSII) under environmental stress ...

Light-Harvesting Protein LHCB4 Is Important for Stable Dimeric Organization of Photosystem II. [PDF]

Physiol Plant
ABSTRACT Light‐harvesting protein LHCB4 is a monomeric antenna of photosystem II (PSII) that connects the PSII core (C) with strongly (S) and moderately (M) bound LHCII trimers, forming the stable dimeric supercomplex C2S2M2. LHCB4 is known to stabilize LHCII attachment to the PSII core dimer (C2).

High-resolution model of Arabidopsis Photosystem II reveals the structural consequences of digitonin-extraction

Scientific Reports, 2021
In higher plants, the photosynthetic process is performed and regulated by Photosystem II (PSII). Arabidopsis thaliana was the first higher plant with a fully sequenced genome, conferring it the status of a model organism; nonetheless, a high-resolution ...

Aggregates of the Chlorophyll-Binding Protein IsiA (CP43‘) Dissipate Energy in Cyanobacteria [PDF]

Biochemistry, 2005
In many natural habitats, growth of cyanobacteria may be limited by a low concentration of iron. Cyanobacteria respond to this condition by expressing a number of iron-stress-inducible genes, of which the isiA gene encodes a chlorophyll-binding protein known as IsiA or CP43'.

In situ cryo-ET structure of phycobilisome–photosystem II supercomplex from red alga

eLife, 2021
Phycobilisome (PBS) is the main light-harvesting antenna in cyanobacteria and red algae. How PBS transfers the light energy to photosystem II (PSII) remains to be elucidated.

Exploring thylakoid emergence: evolution of membrane biogenesis and photosystem II assembly in early-diverging cyanobacteria. [PDF]

New Phytol
Overview of the results. Phylogenetic analyses of 36 assembly factors of photosystem II (PSII) and 13 proteins involved in membrane dynamics summarized in Siebenaller & Schneider (2023) were performed to investigate the taxonomic distributions and structural differences between the thylakoid‐less Gloeobacterales and the Phycobacteria. Summary Thylakoid

The availability of neither D2 nor CP43 limits the biogenesis of photosystem II in tobacco [PDF]

Plant Physiology, 2020
Abstract The pathway of photosystem II (PSII) assembly is well understood, and multiple auxiliary proteins supporting it have been identified, but little is known about rate-limiting steps controlling PSII biogenesis. In the cyanobacterium Synechocystis PCC6803 and the green alga Chlamydomonas reinhardtii, indications exist that the ...

Effect of Low Light on Photosynthetic Performance of Tomato Plants—Ailsa Craig and Carotenoid Mutant Tangerine

Plants, 2023
The effects of a five-day treatment with low light intensity on tomato plants—Ailsa Craig and tangerine mutant—at normal and low temperatures and after recovery for three days under control conditions were investigated.

Arabidopsis STN7/STN8 alleviates oxidative damages via different regulatory patterns under drought stress [PDF]

Plant J
SUMMARY STN7 and STN8 kinases phosphorylate several proteins of the photosynthetic apparatus in response to changes in environmental conditions. Phosphorylation is linked to the dynamic arrangement of both the 3D structure of the thylakoid membrane and thylakoid protein complexes, thereby controlling excitation energy transfer between photosystems and ...
