Iron Deficiency Promotes the Lack of Photosynthetic Cytochrome c550 and Affects the Binding of the Luminal Extrinsic Subunits to Photosystem II in the Diatom Phaeodactylum tricornutum
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
In the diatom Phaeodactylum tricornutum, iron limitation promotes a decrease in the content of photosystem II, as determined by measurements of oxygen-evolving activity, thermoluminescence, chlorophyll fluorescence analyses ...

Metals in Cyanobacteria: Analysis of the Copper, Nickel, Cobalt and Arsenic Homeostasis Mechanisms
(MDPI AG, 2014)
Traces of metal are required for fundamental biochemical processes, such as photosynthesis and respiration. Cyanobacteria metal homeostasis acquires an important role because the photosynthetic machinery imposes a high ...

Systematic screen for mutants resistant to TORC1 inhibition in fission yeast reveals genes involved in cellular ageing and growth
(Company of Biologists: OAJ, 2014)
Target of rapamycin complex 1 (TORC1), which controls growth in response to nutrients, promotes ageing in multiple organisms. The fission yeast Schizosaccharomyces pombe emerges as a valuable genetic model system to study ...

Cuf2 Is a Novel Meiosis-Specific Regulatory Factor of Meiosis Maturation
(Public Library of Science, 2012)
Background Meiosis is the specialized form of the cell cycle by which diploid cells produce the haploid gametes required for sexual reproduction. Initiation and progression through meiosis requires that the expression ...

urg1: A Uracil-Regulatable Promoter System for Fission Yeast with Short Induction and Repression Times
(Public Library of Science, 2008)
Background The fission yeast Schizosaccharomyces pombe is a popular genetic model organism with powerful experimental tools. The thiamine-regulatable nmt1 promoter and derivatives, which take >15 hours for full induction, ...

A metabolic strategy to enhance long-term survival by Phx1 through stationary phase-specific pyruvate decarboxylases in fission yeast
(Impact Journals, 2014)
In the fission yeast Schizosaccharomyces pombe, the stationary phase‐specific transcription factor Phx1 contributes to long‐term survival, stress tolerance, and meiosis. We identified Phx1‐dependent genes through transcriptome ...

Back to the future: Transplanting the chloroplast TrxF–FBPase–SBPase redox system to cyanobacteria
(Frontiers Media S.A., 2022)
Fructose-1,6-bisphosphatase (FBPase) and sedoheptulose-1,7-bisphosphatase (SBPase) are two essential activities in the Calvin–Benson–Bassham cycle that catalyze two irreversible reactions and are key for proper regulation ...

Arsenic sensing and resistance system in the cyanobacterium Synechocystis sp. Strain PCC 6803
(American Society for Microbiology, 2003-09)
Arsenic is one of the most important global environmental pollutants. Here we show that the cyanobacterium Synechocystis sp. strain PCC 6803 contains an arsenic and antimony resistance operon consisting of three genes: ...

Interlaboratory Reproducibility in Growth and Reporter Expression in the Cyanobacterium Synechocystis sp. PCC 6803
(American Chemical Society, 2023)
In recent years, a plethora of new synthetic biology tools for use in cyanobacteria have been published; however, their reported characterizations often cannot be reproduced, greatly limiting the comparability of results ...

Genomic responses to arsenic in the cyanobacterium Synechocystis sp. PCC 6803
(Public Library of Science, 2014)
Arsenic is a ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [AsIII] and arsenate [AsV]. Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by the ...
