Branching and intercellular communication in the Section V cyanobacterium Mastigocladus laminosus, a complex multicellular prokaryote
(wiley, 2014)
The filamentous Section V cyanobacterium Mastigocladus laminosus is one of the most morphologically complex prokaryotes. It exhibits cellular division in multiple planes, resulting in the formation of true branches, and ...

Current knowledge on mechanisms preventing photosynthesis redox imbalance in plants
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Photosynthesis includes a set of redox reactions that are the source of reducing power and energy for the assimilation of inorganic carbon, nitrogen and sulphur, thus generating organic compounds, and oxygen, which supports ...

Plastid 2-Cys peroxiredoxins are essential for embryogenesis in Arabidopsis
(Elsevier, 2023)
The redox couple formed by NADPH-dependent thioredoxin reductase C (NTRC) and 2-Cys peroxiredoxins (Prxs) allows fine-tuning chloroplast performance in response to light intensity changes. Accordingly, the Arabidopsis 2cpab ...

Exploring the Diversity of the Thioredoxin Systems in Cyanobacteria
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Cyanobacteria evolved the ability to perform oxygenic photosynthesis using light energy to reduce CO2 from electrons extracted from water and form nutrients. These organisms also devel-oped light-dependent redox regulation ...

Reconstitution, spectroscopy, and redox properties of the photosynthetic recombinant cytochrome b 559 from higher plants
(Springer Verlag, 2012)
A study of the in vitro reconstitution of sugar beet cytochrome b 559 of the photosystem II is described. Both α and β cytochrome subunits were first cloned and expressed in Escherichia coli. In vitro reconstitution of ...

Site-directed Mutagenesis of Cytochromec 6 from Anabaena Species PCC 7119
(Elsevier, 1999)
A number of surface residues of cytochromec 6 from the cyanobacterium Anabaenasp. PCC 7119 have been modified by site-directed mutagenesis. Changes were made in six amino acids, two near the heme group (Val-25 and Lys-29) ...

New Arabidopsis thaliana cytochrome c partners: A look into the elusive role of cytochrome c in programmed cell death in plants
(American Society for Biochemistry and Molecular Biology, 2013)
Programmed cell death is an event displayed by many different organisms along the evolutionary scale. In plants, programmed cell death is necessary for development and the hypersensitive response to stress or pathogenic ...

Beyond toxicity: A regulatory role for mitochondrial cyanide
(Landes Bioscience, 2014)
In non-cyanogenic plants, cyanide is a co-product of ethylene and camalexin biosynthesis. To maintain cyanide at non-toxic levels, Arabidopsis plants express the mitochondrial β-cyanoalanine synthase CYS-C1. CYS-C1 knockout ...

A comprehensive analysis of the peroxiredoxin reduction system in the Cyanobacterium Synechocystis sp. strain PCC 6803 reveals that all five peroxiredoxins are thioredoxin dependent
(2009)
Cyanobacteria perform oxygenic photosynthesis, which gives rise to the continuous production of reactive oxygen species, such as superoxide anion radicals and hydrogen peroxide, particularly under unfavorable growth ...

Continuous culture methodology for the screening of microalgae for oil
(Elsevier, 2015)
A basic criterion in the selection of microalgae suitable as source of oil for biodiesel should be their actual capacity to produce lipids or, more properly, the fatty acid yield. Performance assessment of ten preselected ...
