The Highly Conserved Cys95 Residue of Fructose-1,6-Bisphosphatase 1 Mediates the pH-Driven Structure and Activity of the Enzyme and Photosynthesis. [PDF]

Plant Cell Environ
ABSTRACT In Arabidopsis, exposure to microbial volatile compounds promotes thiol reduction of the Cys95 residue of the photosynthetic enzyme fructose‐1,6‐bisphosphatase (cFBP1). Although highly conserved in plants, the Cys95 function still remains unknown. We characterised recombinant wild‐type (WT) cFBP1 and a variant (C95S) in which the Cys95 residue

Transcriptomic analysis reveals the participation of NTRC in iron homeostasis in Arabidopsis. [PDF]

Physiol Plant
Abstract NADPH‐dependent thioredoxin reductase C (NTRC) plays a central role in redox regulation of chloroplast photosynthetic metabolism. Accordingly, Arabidopsis (Arabidopsis thaliana) NTRC‐null mutants show defective photosynthetic performance and growth inhibition.

The Role of Mre Factors and Cell Division in Peptidoglycan Growth in the Multicellular Cyanobacterium Anabaena

mBio, 2022
Bacteria in general serve two main tasks: cell growth and division. Both processes include peptidoglycan extension to allow cell expansion and to form the poles of the daughter cells, respectively.

An open-source LED lamp for use with the LI-6800 photosynthesis system. [PDF]

Appl Plant Sci
Abstract Premise Controlling light flux density during carbon dioxide assimilation measurements is essential in photosynthesis research. Commercial lamps are expensive and are based on monochromatic light‐emitting diodes (LEDs), which deviate significantly in their spectral distribution compared to sunlight.

Cytochrome c_M Is Probably a Membrane Protein Similar to the C Subunit of the Bacterial Nitric Oxide Reductase

Applied Sciences, 2021
Cytochrome cM was first described in 1994 and its sequence has been found in the genome of manifold cyanobacterial species ever since. Numerous studies have been carried out with the purpose of determining its function, but none of them has given place ...

Interactions of PatA with the Divisome during Heterocyst Differentiation in Anabaena

mSphere, 2020
The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric N2 and provide the vegetative ...

Sustaining Rice Production through Biofertilization with N₂-Fixing Cyanobacteria

Applied Sciences, 2021
Current agricultural productivity depends on an exogenous nutrient supply to crops. This is of special relevance in cereal production, a fundamental part of the trophic chain that plays a vital role in the human diet.

The Role of MreB, MreC and MreD in the Morphology of the Diazotrophic Filament of Anabaena sp. PCC 7120

Life, 2022
The cyanobacterium Anabaena sp. PCC 7120 forms filaments of communicating cells. Under conditions of nitrogen scarcity, some cells differentiate into heterocysts, allowing the oxygen-sensitive N2-reduction system to be expressed and operated in oxic ...

Plants maximise chloride uptake during early vegetative development to stimulate cell expansion, maturation of the photosynthetic apparatus, and growth. [PDF]

Plant J
SUMMARY Despite being an essential micronutrient and its recent classification as a beneficial macronutrient, chloride (Cl−) has traditionally been considered of limited agricultural relevance and a potentially toxic saline ion. This study provides the first comprehensive demonstration of the quantitative and qualitative importance of Cl− during early ...
