Isolation of Ribosomal Particles from the Unicellular Cyanobacterium Synechocystis sp. PCC 6803

open access: yesBio-Protocol, 2017
Isolation of ribosomal particles is an essential step in the study of ribosomal components as well as in the analysis of trans-acting factors that interact with the ribosome to regulate protein synthesis and modulate the expression profile of the cell in

ThyD Is a Thylakoid Membrane Protein Influencing Cell Division and Acclimation to High Light in the Multicellular Cyanobacterium Anabaena sp. Strain PCC 7120

open access: yesMolecular Microbiology, Volume 123, Issue 1, Page 31-47, January 2025.
Anabaena performs oxygenic photosynthesis in vegetative cells and N2 fixation in heterocysts. The protein ThyD is localized in thylakoid membranes: at the cell periphery in vegetative cells (v) and the cell poles in heterocyst (h). ThyD influences cell division and is required for acclimation to conditions of high light intensity.

Metals in Cyanobacteria: Analysis of the Copper, Nickel, Cobalt and Arsenic Homeostasis Mechanisms

open access: yesLife, 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 demand for metals, making them a ...

Stable isotope analysis indicates partial mycoheterotrophy in arbuscular mycorrhizal woody seedlings in tropical forests

open access: yesFunctional Ecology, Volume 38, Issue 12, Page 2720-2733, December 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Chlorophyllous plants exhibiting partial mycoheterotrophy obtain carbon through mycorrhizal interactions in addition to photosynthesis. In arbuscular mycorrhizal (AM) plants, the Paris‐morphotype (i.e.

Seasonal acclimation of photosynthetic thermal tolerances in six woody tropical species along a thermal gradient

open access: yesFunctional Ecology, Volume 38, Issue 11, Page 2493-2505, November 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Extreme heat events are becoming increasingly common, and the short‐term acclimation of photosynthesis will have a large impact on plant performance. Trees in lowland tropical forests, which are hypothesized to have limited abilities to tolerate rising temperatures, may

Amino Acid Transporters and Release of Hydrophobic Amino Acids in the Heterocyst-Forming Cyanobacterium Anabaena sp. Strain PCC 7120

open access: yesLife, 2015
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that can use inorganic compounds such as nitrate or ammonium as nitrogen sources. In the absence of combined nitrogen, it can fix N2 in differentiated cells called heterocysts.
