Signaling by hydrogen sulfide and cyanide through post-translational modification
(Oxford University Press, 2019)
Two cysteine metabolism-related molecules, hydrogen sulfide and hydrogen cyanide, which are considered toxic, have now been considered as signaling molecules. Hydrogen sulfide is produced in chloroplasts through the activity ...

Specific mutations in the permease domain of septal protein SepJ differentially affect functions related to multicellularity in the filamentous cyanobacterium Anabaena
(Shared Science Publishers, 2018)
Filamentous, heterocyst-forming cyanobacteria are multicellular organisms in which growth requires the activity of two interdependent cell types that exchange nutrients and regulators. Vegetative cells provide heterocysts ...

Intercellular Diffusion of a Fluorescent Sucrose Analog via the Septal Junctions in a Filamentous Cyanobacterium
(American Society for Microbiology, 2015)
Many filamentous cyanobacteria produce specialized nitrogen-fixing cells called heterocysts, which are located at semiregular intervals along the filament with about 10 to 20 photosynthetic vegetative cells in between. ...

Assessing the Epigenetic Status of Human Telomeres
(MDPI, 2019)
The epigenetic modifications of human telomeres play a relevant role in telomere functions and cell proliferation. Therefore, their study is becoming an issue of major interest. These epigenetic modifications are usually ...

Arabidopsis thaliana plastoglobule-associated fibrillin 1a interacts with fibrillin 1b in vivo
(wiley, 2014)
Plant fibrillins are a well-conserved protein family found in the plastids of all photosynthetic organisms, where they perform a wide range of functions. A number of these proteins have been suggested to be involved in the ...

An event of alternative splicing affects the expression of the NTRC gene, encoding NADPH-thioredoxin reductase C, in seed plants
(Elsevier, 2017)
The NTRCgene encodes aNADPH-dependentthioredoxin reductase with a joint thioredoxin domain, exclusive ofphotosynthetic organisms. An updated search of NTRCgenesshows that althoughmost species harbor a single ...

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 ...

Identification of the direct regulon of NtcA during early acclimation to nitrogen starvation in the cyanobacterium Synechocystis sp. PCC 6803
(Oxford University Press, 2017)
In cyanobacteria, nitrogen homeostasis is maintained by an intricate regulatory network around transcription factor NtcA. Although mechanisms controlling NtcA activity appear to be well understood, its regulon remains ...

Enhancing the expression of starch synthase class IV results in increased levels of both transitory and long-term storage starch
(Wiley Open Access, 2011)
Starch is an important renewable raw material with an increasing number of applications.Several attempts have been made to obtain plants that produce modified versions of starchor higher starch yield. Most of the approaches ...
