Algae.

Algae are versatile photosynthetic organisms, with remarkable adaptability and metabolic properties that allow them to live in diverse and extreme habitats, as well as holding great potential for biotechnology. They play fundamental roles in their environments, including primary production, carbon fixation, and engineering their ecosystems. Advances in research on these organisms have been lagging behind bacteria, fungi, plants and animals, but the situation is rapidly evolving thanks to the development of new tools and resources.

Multi-omic profiles of Sorghum genotypes with contrasting heat tolerance connect pathways related to thermotolerance.

Understanding how crop varieties acclimate to elevated temperatures is key to priming them for future climates. Here, we exposed two genotypes of Sorghum bicolor (one sensitive to heat shock (Sen) and one tolerant (Tol)) from multiple growth temperatures to a six-day heat shock (reaching 45°C), carrying out a suite of measurements before and during heat shock. Sen consistently reduced photosynthetic functioning during heat shock, while Tol increased its photosynthetic rate.

Biomining using microalgae to recover rare earth elements (REEs) from bauxite.

Biomining using microalgae has emerged as a sustainable option to extract rare earth elements (REEs). This study aims to (i) explore the capability of REEs recovery from bauxite by microalgae, (ii) assess the change of biochemical function affected by bauxite, and (iii) investigate the effects of operating conditions (i.e.

A fungi hotspot deep in the ocean: explaining the presence of Gjaerumia minor in equatorial Pacific bathypelagic waters.

A plant parasite associated with the white haze disease in apples, the Basidiomycota Gjaerumia minor, has been found in most samples of the global bathypelagic ocean. An analysis of environmental 18S rDNA sequences on 12 vertical profiles of the Malaspina 2010 expedition shows that the relative abundance of this cultured species increases with depth while its distribution is remarkably different between the deep waters of the Pacific and Atlantic oceans, being present in higher concentrations in the former. This is evident from sequence analysis and a microscopic survey with a species-specific newly designed TSA-FISH probe.
