Molecular 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
Life, 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 ...

Functional 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.

Functional 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

Journal of Ecology, Volume 112, Issue 9, Page 2107-2122, September 2024.Tree species diversity promotes below‐ground water source partitioning in mixed oak and pine stands, potentially reducing competition for water in more diverse ecosystems. Yet, these results show that it is insufficient to buffer the adverse impacts of severe droughts on above‐ground tree carbon and water use, leading to higher water stress, especially
