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 ...

Arabidopsis metacaspase MC1 localizes in stress granules, clears protein aggregates, and delays senescence
(American Society of Plant Biologists, 2023-07-01)
Stress granules (SGs) are highly conserved cytoplasmic condensates that assemble in response to stress and contribute to maintaining protein homeostasis. These membraneless organelles are dynamic, disassembling once the ...

Coordinated Transport of Nitrate, Potassium, and Sodium
(Frontiers Media, 2020)
Potassium (K+) and nitrogen (N) are essential nutrients, and their absorption and distribution within the plant must be coordinated for optimal growth and development. Potassium is involved in charge balance of inorganic ...

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 Integrity of the Cell Wall and Its Remodeling during Heterocyst Differentiation Are Regulated by Phylogenetically Conserved Small RNA Yfr1 in Nostoc sp. Strain PCC 7120
(American Society for Microbiology, 2020)
Yfr1 is a strictly conserved small RNA in cyanobacteria. A bioinformatic prediction to identify possible interactions of Yfr1 with mRNAs was carried out by using the sequences of Yfr1 from several heterocyst-forming strains, ...

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 ...

Proposed mechanism for regulation of H2O2-induced programmed cell death in plants by binding of cytochrome c to 14-3-3 proteins
(Wiley-Blackwell, 2021-04)
Programmed cell death (PCD) is crucial for development and homeostasis of all multicellular organisms. In human cells, the double role of extra-mitochondrial cytochrome c in triggering apoptosis and inhibiting survival ...
