Beta-Cyanoalanine synthase action in root hair elongation is exerted at early steps of the root hair elongation pathway and is independent of direct cyanide inactivation of NADPH oxidase
(Oxford University Press, 2018)
In Arabidopsis thaliana, cyanide is produced concomitantly with ethylene biosynthesis and is mainly detoxified by the ß-cyanoalanine synthase CAS-C1. In roots, CAS-C1 activity is essential to maintain a low level of cyanide ...

Regulation of K+ Nutrition in Plants
(Frontiers Media, 2019)
Modern agriculture relies on mineral fertilization. Unlike other major macronutrients, potassium (K+) is not incorporated into organic matter but remains as soluble ion in the cell sap contributing up to 10% of the dry ...

Oxidative stress contributes to autophagy induction in response to endoplasmic reticulum stress in Chlamydomonas
(American Society of Plant Biologists, 2014)
The accumulation of unfolded/misfolded proteins in the endoplasmic reticulum (ER) results in the activation of stress responses such as the unfolded protein response or the catabolic process of autophagy to ultimately ...

H2A monoubiquitination in Arabidopsis thaliana is generally independent of LHP1 and PRC2 activity
(BioMed Central, 2017)
Background: Polycomb group complexes PRC1 and PRC2 repress gene expression at the chromatin level in eukaryotes. The classic recruitment model of Polycomb group complexes in which PRC2-mediated H3K27 trimethylation ...

A comparison between nuclear dismantling during plant and animal programmed cell death
(Elsevier, 2012)
Programmed cell death (PCD) is a process of organized destruction of cells, essential for the development and maintenance of cellular homeostasis of multicellular organisms. Cells undergoing PCD begin a degenerative process ...

The ciliate protist tetrahymena pyriformis as a cellular adhesion model for the pathogenic bacterium staphylococcus aureus
(Scientific Research Publishing, 2017)
Staphylococcus aureus is one of the main pathogenic agents responsible for nosocomial and community-acquired bacterial infections. The pathogenicity of this Gram-positive bacterium is ensured by its different adhesion ...

The TOR Signaling Network in the Model Unicellular Green Alga Chlamydomonas reinhardtii
(MDPI, 2017)
Cell growth is tightly coupled to nutrient availability. The target of rapamycin (TOR) kinase transmits nutritional and environmental cues to the cellular growth machinery. TOR functions in two distinct multiprotein ...

The E. coli S30 lysate proteome: A prototype for cell-free protein production
(Elsevier, 2018)
Protein production using processed cell lysates is a core technology in synthetic biology and these systems are excellent to produce difficult toxins or membrane proteins. However, the composition of the central lysate of ...

Intrinsically disordered inhibitor of glutamine synthetase is a functional protein with random-coil-like pKa values
(Wiley-Blackwell, 2017)
The sequential action of glutamine synthetase (GS) and glutamate synthase (GOGAT) in cyanobacteria allows the incorporation of ammonium into carbon skeletons. In the cyanobacterium Synechocystis sp. PCC 6803, the activity ...

Nitration of tyrosine 74 prevents human cytochrome c to play a key role in apoptosis signaling by blocking caspase-9 activation
(Elsevier, 2010)
Tyrosine nitration is one of the most common post-transcriptional modifications of proteins, so affecting their structure and function. Human cytochrome c, with five tyrosine residues, is an excellent case study as it is ...
