Persulfidation protects from oxidative stress under nonphotorespiratory conditions in Arabidopsis
(Wiley-Blackwell, 2023)
Hydrogen sulfide is a signaling molecule in plants that regulates essential biological processes through protein persulfidation. However, little is known about sulfide-mediated regulation in relation to photorespiration. ...

Overoxidation of 2-cys peroxiredoxin in prokaryotes: Cyanobacterial 2-cys peroxiredoxins sensitive to oxidative stress
(Elsevier, 2010)
In eukaryotic organisms, hydrogen peroxide has a dual effect; it is potentially toxic for the cell but also has an important signaling activity. According to the previously proposed floodgate hypothesis, the signaling ...

Characterization of TrxC, an Atypical Thioredoxin Exclusively Present in Cyanobacteria
(MDPI, 2018)
Cyanobacteria form a diverse group of oxygenic photosynthetic prokaryotes considered to be the antecessor of plant chloroplast. They contain four different thioredoxins isoforms, three of them corresponding to m, x and y ...

Predicting substrate exchange in marine diatom-heterocystous cyanobacteria symbioses
(Wiley, 2020)
In the open ocean, some phytoplankton establish symbiosis with cyanobacteria. Some partnerships involve diatoms as hosts and heterocystous cyanobacteria as symbionts. Heterocysts are specialized cells for nitrogen fixation, ...

You have access HCN regulates cellular processes through posttranslational modification of proteins by S-cyanylation
(American Society of Plant Biologists, 2019)
Hydrogen cyanide (HCN) is coproduced with ethylene in plant cells and is primarily enzymatically detoxified by the mitochondrial β-CYANOALANINE SYNTHASE (CAS-C1). Permanent or transient depletion of CAS-C1 activity in ...

FtsZ of filamentous, heterocyst-forming cyanobacteria has a conserved N-Terminal peptide required for normal FtsZ polymerization and cell division
(Frontiers Media, 2018-10-02)
Filamentous cyanobacteria grow by intercalary cell division, which should involve distinct steps compared to those producing separate daughter cells. The N-terminal region of FtsZ is highly conserved in the clade of ...

FraH is required for reorganization of intracellular membranes during heterocyst differentiation in Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2011)
In the filamentous, heterocyst-forming cyanobacteria, two different cell types, the CO2-fixing vegetative cells and the N2-fixing heterocysts, exchange nutrients and regulators for diazotrophic growth. In the model organism ...

Phosphorus Availability Regulates TORC1 Signaling via LST8 in Chlamydomonas
(American Society of Plant Biologists, 2020)
Target of rapamycin complex 1 (TORC1) is a central regulator of cell growth. It balances anabolic and catabolic processes in response to nutrients, growth factors, and energy availability. Nitrogen- and carbon-containing ...

A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium
(Wiley, 2017-06-06)
Heterocystous cyanobacteria such as Nostoc sp. are filamentous photosynthetic organisms that, in response to nitrogen deficiency, undergo a differentiation process transforming certain, semi-regularly spaced cells into ...
