Negative Regulation of Autophagy by Sulfide Is Independent of Reactive Oxygen Species
(American Society of Plant Biologists, 2016)
Accumulating experimental evidence in mammalian, and recently plant, systems has led to a change in our understanding of the role played by hydrogen sulfide in life processes. In plants, hydrogen sulfide mitigates stress ...

Mutations of Cytochrome b559 and PsbJ on and near the QC Site in Photosystem II Influence the Regulation of Short-Term Light Response and Photosynthetic Growth of the Cyanobacterium Synechocystis sp. PCC 6803
(American Chemical Society, 2016)
The characteristic features of two types of short-term light adaptations of the photosynthetic apparatus of the cyanobacterium Synechocystis sp. PCC 6803, state transition and blue-green light-induced fluorescence quenching, ...

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 ...

The photosynthetic cytochrome c550 from the diatom Phaeodactylum tricornutum
(Springer Verlag, 2016)
The photosynthetic cytochrome c550 from the marine diatom Phaeodactylum tricornutum has been purified and characterized. Cytochrome c550 is mostly obtained from the soluble cell extract in relatively large amounts. In ...

Novel features of telomere biology revealed by the absence of telomeric DNA methylation
(Cold Spring Harbor Laboratory Press, 2016)
Cytosine methylation regulates the length and stability of telomeres, which can affect a wide variety of biological features, including cell differentiation, development, or illness. Although it is well established that ...

Inorganic Polyphosphate in the Microbial World. Emerging Roles for a Multifaceted Biopolymer
(Springer Verlag, 2016)
inorganic polyphosphates (polyP) are linear polymers of tens to hundreds orthophosphate residues linked by phosphoanhydride bonds. These fairly abundant biopolymers occur in all extant forms of life, from prokaryotes to ...

The heterocyst differentiation transcriptional regulator HetR of the filamentous cyanobactrium Anabaena forms tetramers and can be regulated by phosphorylation
(Wiley, 2016)
Many filamentous cyanobacteria respond to the external cue of nitrogen scarcity by the differentiation of heterocysts, cells specialized in the fixation of atmospheric nitrogen in oxic environments. Heterocysts follow a ...

Septal Junctions in Filamentous Heterocyst-Forming Cyanobacteria
(Elsevier, 2016)
In the filaments of heterocyst-forming cyanobacteria, septal junctions that traverse the septal peptidoglycan join adjacent cells, allowing intercellular communication. Perforations in the septal peptidoglycan have been ...

The chloroplast NADPH thioredoxin reductase C, NTRC, controls non-photochemical quenching of light energy and photosynthetic electron transport in Arabidopsis
(Wiley-Blackwell, 2016)
High irradiances may lead to photooxidative stress in plants, and non-photochemical quenching (NPQ) contributes to protection against excess excitation. One of the NPQ mechanisms, qE, involves thermal dissipation of the ...

New challenges in microalgae biotechnology
(Elsevier, 2016)
Photosynthetic protists, also called microalgae, have been systematically studied for more than a century. However, only recently broad biotechnological applications have fostered a novel wave of research on their ...
