Modelling growth and CO2 fixation by Scenedesmus vacuolatus in continuous culture
(Elsevier, 2017)
A promising approach to CO2 abatement is the use of photosynthetic microorganisms. Different microalgae (Chloroccocum sp., Porphyridium purpureum, Scenedesmus vacuolatus) and cyanobacteria (Anabaena PCC7119, Anabaena ...

Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley
(Company of Biologists, 2018)
Microspores are reprogrammed towards embryogenesis by stress. Many microspores die after this stress, limiting the efficiency of microspore embryogenesis. Autophagy is a degradation pathway that plays critical roles in ...

Arabidopsis S-Sulfocysteine Synthase Activity Is Essential for Chloroplast Function and Long-Day Light-Dependent Redox Control
(American Society of Plant Biologists, 2010)
In bacteria, the biosynthesis of Cys is accomplished by two enzymes that are encoded by the cysK and cysM genes. CysM is also able to use thiosulfate as a substrate to produce S-sulfocysteine. In plant cells, the biosynthesis ...

Human Long Telomeres and Epigenetic Marks
(Scientific Research Publishing, 2013)
We have read with interest the article “Telomere length regulates TERRA levels through increased trimethylation of telomeric H3K9 and HP1α” by Arnoult and colleagues [1]. This study focuses on human telomeric chromatin ...

Mitochondrial Sulfide Detoxification Requires a Functional Isoform O-Acetylserine(thiol)lyase C in Arabidopsis thaliana
(Oxford University Press, 2012)
In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolised by the β-Cyanoalanine ...

NtcA is responsible for accumulation of the small isoform of ferredoxin:NADP oxidoreductase
(Microbiology Society, 2014-04-01)
In several cyanobacteria, petH, the gene encoding ferredoxin:NADP oxidoreductase (FNR), is transcribed from at least two promoters depending on growth conditions. Two transcripts (short and long) are translated from two ...

Two strictly polyphosphate-dependent gluco(manno)kinases from diazotrophic Cyanobacteria with potential to phosphorylate hexoses from polyphosphates
(Springer, 2015)
The single-copy genes encoding putative polyphosphate–glucose phosphotransferases (PPGK, EC 2.7.1.63) from two nitrogen-fixing Cyanobacteria, Nostoc sp. PCC7120 and Nostoc punctiforme PCC73102, were cloned and functionally ...

Control of autophagy in Chlamydomonas is mediated through redox dependent inactivation of the ATG4 protease
(American Society of Plant Biologists, 2016)
Autophagy is a major catabolic pathway by which eukaryotic cells deliver unnecessary or damaged cytoplasmic material to the vacuole for its degradation and recycling in order to maintain cellular homeostasis. Control of ...

Hydrogen Sulfide Generated by L-Cysteine Desulfhydrase Acts Upstream of Nitric Oxide to Modulate Abscisic Acid-Dependent Stomatal Closure
(American Society of Plant Biologists, 2014)
Abscisic acid (ABA) is a well-studied regulator of stomatal movement. Hydrogen sulfide (H2S), a small signaling gas molecule involved in key physiological processes in mammals, has been recently reported as a new component ...

The ancient phosphatidylinositol 3-kinase signaling system is a master regulator of energy and carbon metabolism in algae
(American Society of Plant Biologists, 2018)
Algae undergo a complete metabolic transformation under stress by arresting cell growth, inducing autophagy and hyperaccumulating biofuel precursors such as triacylglycerols and starch. However, the regulatory mechanisms ...
