The ancient phylum Actinobacteria is composed of phylogenetically and physiologically
diverse bacteria that help Earth's ecosystems function. As free-living organisms and …

The molecular clock presents a means of estimating evolutionary rates and timescales using
genetic data. These estimates can lead to important insights into evolutionary processes and …

Abstract The Molecular Evolutionary Genetics Analysis (MEGA) software has matured to
contain a large collection of methods and tools of computational molecular evolution. Here …

Background Among the most consequential unknowns of the devastating COVID-19
pandemic are the durability of immunity and time to likely reinfection. There are limited direct …

The durability of vaccine-mediated immunity to SARS-CoV-2, the durations to breakthrough
infection, and the optimal timings of booster vaccination are crucial knowledge for pandemic …

Mutations that accumulate in the genome of cells or viruses can be used to infer their
evolutionary history. In the case of rapidly evolving organisms, genomes can reveal their …

Photosynthesis is a fundamental biogeochemical process, thought to be restricted to a few
bacterial and eukaryotic phyla. However, understanding the origin and evolution of …

We present the latest version of the Molecular Evolutionary Genetics Analysis (M ega)
software, which contains many sophisticated methods and tools for phylogenomics and …

We announce the release of an advanced version of the Molecular Evolutionary Genetics
Analysis (MEGA) software, which currently contains facilities for building sequence …

Genomic data are rapidly resolving the tree of living species calibrated to time, the timetree
of life, which will provide a framework for research in diverse fields of science. Previous …
