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

Life, 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.

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

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

Concepciones de los estudiantes de un contexto rural sobre la fotosíntesis

Praxis & Saber, 2020
La fotosíntesis es uno de los ejes temáticos más conflictivos para los estudiantes, por un lado, por su falta de comprensión y, por otro, es el tema con el cual más dificultades acumulan.

Drought effects in Mediterranean forests are not alleviated by diversity‐driven water source partitioning

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

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 ...

Transcriptomic characterization of the response to a microalgae extract in Arabidopsis thaliana and Solanum lycopersicum

Journal of the Science of Food and Agriculture, Volume 104, Issue 10, Page 5789-5798, 15 August 2024.
Abstract BACKGROUND The steady world population growth and the current climate emergency crisis demand the development of sustainable methods to increase crop performance and resilience to the abiotic and biotic stresses produced by global warming.

Glycogen synthesis prevents metabolic imbalance and disruption of photosynthetic electron transport from photosystem II during transition to photomixotrophy in Synechocystis sp. PCC 6803

New Phytologist, Volume 243, Issue 1, Page 162-179, July 2024.
Summary Some cyanobacteria can grow photoautotrophically or photomixotrophically by using simultaneously CO2 and glucose. The switch between these trophic modes and the role of glycogen, their main carbon storage macromolecule, was investigated.

Lipid turnover through lipophagy in the newly identified extremophilic green microalga Chlamydomonas urium

New Phytologist, Volume 243, Issue 1, Page 284-298, July 2024.
Summary Autophagy is a central degradative pathway highly conserved among eukaryotes, including microalgae, which remains unexplored in extremophilic organisms. In this study, we described and characterized autophagy in the newly identified extremophilic green microalga Chlamydomonas urium, which was isolated from an acidic environment.

Pushing the limits of C3 intrinsic water use efficiency in Mediterranean semiarid steppes: Responses of a drought‐avoider perennial grass to climate aridification

Functional Ecology, Volume 38, Issue 4, Page 955-966, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intrinsic water use efficiency (WUEi) reflects the trade‐off between photosynthetic carbon gain and water loss through stomatal conductance and is key for understanding dryland plant responses to climate change.
