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.

La basura y el ciclo de los materiales [PDF]
, 2013 La circulación de los materiales en los ecosistemas es un concepto algo abstracto y difícil de enseñar. En el ciclo natural de los materiales, sustancias como carbono, agua, nitrógeno o calcio se transfieren sucesivamente de vegetales a herbívoros,

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.

Developmental Biology in Cyanobacteria
Life, 2019 Filamentous, heterocyst-forming cyanobacteria are phototrophic multicellular organisms in which N2-fixing heterocysts and CO2-fixing vegetative cells exchange regulators and nutrients [...]

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.

Regulation of K+ Nutrition in Plants
Frontiers in Plant Science, 2019 Modern agriculture relies on mineral fertilization. Unlike other major macronutrients, potassium (K+) is not incorporated into organic matter but remains as soluble ion in the cell sap contributing up to 10% of the dry organic matter.

Global status, impacts, and management of rocky temperate mesophotic ecosystems
Conservation Biology, Volume 38, Issue 1, February 2024.Abstract The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20–150 m (the limit of photosynthesis), and on rocky substratum they support rich benthic communities and mobile fauna.

Photosynthetic Adaptation to Length of Day Is Dependent on S-Sulfocysteine Synthase Activity in the Thylakoid Lumen [PDF]
, 2012 Arabidopsis (Arabidopsis thaliana) chloroplasts contain two O-acetyl-serine(thiol)lyase (OASTL) homologs, OAS-B, which is an authentic OASTL, and CS26, which has S-sulfocysteine synthase activity.
