Protists are the dominant eukaryotes in the biosphere where they play key functional roles.
While protists have been studied for over a century, it is the high-throughput sequencing of …

Most of the genetic, cellular, and biochemical diversity of life rests within single-celled
organisms—the prokaryotes (bacteria and archaea) and microbial eukaryotes (protists) …

A central question in evolutionary biology is whether sponges or ctenophores (comb jellies)
are the sister group to all other animals. These alternative phylogenetic hypotheses imply …

We breathe at the molecular level when mitochondria in our cells consume oxygen to extract
energy from nutrients. Mitochondria are characteristic cellular organelles that derive from …

Molecular phylogenetics of microbial eukaryotes has reshaped the tree of life by
establishing broad taxonomic divisions, termed supergroups, that supersede the traditional …

The evolution of obligate host-association of bacterial symbionts and pathogens remains
poorly understood. The Rickettsiales are an alphaproteobacterial order of obligate …

Plant (archaeplastid) evolution has transformed the biosphere, but we are only now
beginning to learn how this took place through comparative genomics, phylogenetics, and …

The Viridiplantae comprise two main clades, the Chlorophyta (including a diverse array of
marine and freshwater green algae) and the Streptophyta (consisting of the freshwater …

Microalgae are a source of scientific curiosity and inspiration for their utilization as
'inoculants' in agriculture and the commercial production of high-value products. Their …

Phylogenomic analyses have boosted our understanding of the evolutionary trajectories of
all living forms by providing continuous improvements to the tree of life. 1, 2, 3, 4, 5 Within …
