This study traces the evolution of microbial alkaline phosphatases and shows their role in phosphorus recycling through geological time, highlighting their expansion during the Neoproterozoic and their association with specific metabolic strategies.

This study uses phylogenomic analysis to trace the timing of nutrient limitation genes across Earth's history, showing phosphorus genes emerged early, nitrogen later, and iron-related siderophores possibly as early as the Archean.

This study shows microbial exoenzymes played a key role in Earth's oxygenation by enhancing nutrient recycling and supporting cyanobacterial productivity.

This study uses phylogenomic analysis to show that molybdenum-dependent enzymes existed as early as 3.4 billion years ago, suggesting Mo was bioavailable in ancient oceans.

This paper investigates how atmospheric CO2 and O2 levels affect nitrogen isotope signatures in nitrogen fixation by cyanobacteria, finding stable signals with correlations to CO2, light, and toxin production.

The paper reconstructs the evolutionary timeline of phosphorus-cycling enzymes and links their development to changes in phosphate concentrations and geological events.

This study estimates the origin of ammonia-oxidizing bacteria (AOB) using eukaryotic fossils and Bayesian dating, finding they emerged between 2.1 and 1.9 billion years ago.
