Adaptation to an Intracellular Lifestyle by a Nitrogen-Fixing, Heterocyst-Forming Cyanobacterial Endosymbiont of a Diatom
(Frontiers Media, 2022)
The symbiosis between the diatom Hemiaulus hauckii and the heterocyst-forming cyanobacterium Richelia intracellularis makes an important contribution to new production in the world’s oceans, but its study is limited by ...

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 ...

Modulation of copper site properties by remote residues determines the stability of plastocyanins
(Elsevier, 2010)
The metal cofactor determines the thermal stability in cupredoxins, but how the redox state of copper modulates their melting points remains unknown. The metal coordination environment is highly conserved in cyanobacterial ...

Autophagic flux is required for the synthesis of triacylglycerols and ribosomal protein turnover in Chlamydomonas
(Company of Biologists, 2018)
Autophagy is an intracellular catabolic process that allows cells to recycle unneeded or damaged material to maintain cellular homeostasis. This highly dynamic process is characterized by the formation of double-membrane ...

Photoperiodic control of carbon distribution during the floral transition in Arabidopsis
(American Society of Plant Biologists, 2014)
Flowering is a crucial process that demands substantial resources. Carbon metabolism must be coordinated with development through a control mechanism that optimizes fitness for any physiological need and growth stage of ...

Redox interference in nitrogen status via oxidative stress is mediated by 2-oxoglutarate in cyanobacteria
(Wiley-Blackwell, 2019)
Reactive oxygen species (ROS) are generated naturally in photosynthetic organisms by respiration and photosynthesis. Therefore, detoxification of these compounds, avoiding oxidative stress, is essential for proper cell ...

Activation of Autophagy by Metals in Chlamydomonas reinhardtii
(ASM International, 2015)
Autophagy is an intracellular self-degradation pathway by which eukaryotic cells recycle their own material in response to specific stress conditions. Exposure to high concentrations of metals causes cell damage, although ...

Hydrogen sulfide regulates the cytosolic/nuclear partitioning of glyceraldehyde-3-phosphate dehydrogenase by enhancing its nuclear localization
(Oxford University Press, 2017)
Hydrogen sulfide is an important signaling molecule comparable with nitric oxide and hydrogen peroxide in plants. The underlying mechanism of its action is unknown, although it has been proposed to be S-sulfhydration. This ...

Deciphering the Role of POLYCOMB REPRESSIVE COMPLEX1 Variants in Regulating the Acquisition of Flowering Competence in Arabidopsis
(American Society of Plant Biologists, 2015)
Polycomb group (PcG) proteins play important roles in regulating developmental phase transitions in plants; however, little is known about the role of the PcG machinery in regulating the transition from juvenile to adult ...
