Intercellular communication in the fern endosymbiotic cyanobacterium Nostoc azollae [PDF]

mBio
The water fern Azolla spp. harbors as an endobiont the N2-fixing, filamentous, heterocyst-forming cyanobacterium Nostoc azollae. N. azollae provides the fern with fixed nitrogen permitting its growth in nitrogen-poor environments.

Concepciones de los estudiantes de un contexto rural sobre la fotosíntesis

Praxis & Saber, 2020
La fotosíntesis es uno de los ejes temáticos más conflictivos para los estudiantes, por un lado, por su falta de comprensión y, por otro, es el tema con el cual más dificultades acumulan.

Evolution of multicellularity genes in Cyanobacteria in the lead up to the great oxidation event [PDF]

Communications Biology
Cyanobacteria, considered responsible for the Great Oxidation Event (GOE) that shaped the Earth for the evolution of complex life, are among the most morphologically diverse prokaryotic phyla.

Glucose Uncouples Nitrogen Sensing From Chlorosis via a Photosynthetic Checkpoint in Synechocystis sp. PCC 6803. [PDF]

Physiol Plant
ABSTRACT Cyanobacteria adapt to nitrogen starvation by undergoing chlorosis, a regulated bleaching process that involves the degradation of phycobilisomes, the light‐harvesting antennae complexes, and accumulation of glycogen. While this response is well characterized under photoautotrophic conditions, its modulation by external organic carbon sources ...

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 ...
