Heterocytes, specialized cells for nitrogen fixation in cyanobacteria, are surrounded by heterocyte glycolipids (HGs), which contribute to protection of the nitrogenase enzyme from oxygen. Diverse HGs preserve in the sediment and have been widely used as evidence of past nitrogen fixation, and structural variation has been suggested to preserve taxonomic information and reflect paleoenvironmental conditions. Here, by comprehensive HG identification and screening of HG biosynthetic gene clusters throughout cyanobacteria, we reconstruct the convergent evolutionary history of HG structure, in which different clades produce the same HGs.

Carbonate fluorapatite coatings on phillipsite represent a significant sink of phosphorus in abyssal plains of the western Pacific Ocean.

Proc Natl Acad Sci U S A

February 2025

Department of Earth System Sciences, Center for Earth System Research and Sustainability, University of Hamburg, Hamburg 20146, Germany.

As an essential micronutrient, phosphorus plays a key role in oceanic biogeochemistry, with its cycling intimately connected to the global carbon cycle and climate change. Authigenic carbonate fluorapatite (CFA) has been suggested to represent a significant phosphorus sink in the deep ocean, but its formation mechanisms in oceanic low-productivity settings remain poorly constrained. Applying X-ray absorption near edge structure, transmission electron microscopy, and laser ablation inductively coupled plasma mass spectrometer analyses, we report a unique mineral assemblage where CFA crystals coat phillipsite in abyssal sediments of the East Mariana Basin and the Philippine Sea.

Suppressing Tymovirus replication in plants using a variant of ubiquitin.

PLoS Pathog

January 2025

Department of Microbiology, Faculty of Science, University of Manitoba, Winnipeg, Manitoba, Canada.

RNA viruses have evolved numerous strategies to overcome host resistance and immunity, including the use of multifunctional proteases that not only cleave viral polyproteins during virus replication but also deubiquitinate cellular proteins to suppress ubiquitin (Ub)-mediated antiviral mechanisms. Here, we report an approach to attenuate the infection of Arabidopsis thaliana by Turnip Yellow Mosaic Virus (TYMV) by suppressing the polyprotein cleavage and deubiquitination activities of the TYMV protease (PRO). Performing selections using a library of phage-displayed Ub variants (UbVs) for binding to recombinant PRO yielded several UbVs that bound the viral protease with nanomolar affinities and blocked its function.
