Rhodophyta (or red algae) are a diverse and species‐rich group that forms one of three
major lineages in the Archaeplastida, a eukaryotic supergroup whose plastids arose from a …

The oldest and most wide-ranging signal of biological activity (biosignature) on our planet is
the carbon isotope composition of organic materials preserved in rocks. These biosignatures …

In modern oceans, eukaryotic phytoplankton is dominated by lineages with red algal-derived
plastids such as diatoms, dinoflagellates, and coccolithophores. Despite the ecological …

The mobility of transposable elements (TEs) contributes to evolution of genomes. Their
uncontrolled activity causes genomic instability; therefore, expression of TEs is silenced by …

The early evolutionary history of the chloroplast lineage remains an open question. It is
widely accepted that the endosymbiosis that established the chloroplast lineage in …

Macroalgae are multicellular, aquatic autotrophs that play vital roles in global climate
maintenance and have diverse applications in biotechnology and eco-engineering, which …

The~ 1.6 Ga Tirohan Dolomite of the Lower Vindhyan in central India contains phosphatized
stromatolitic microbialites. We report from there uniquely well-preserved fossils interpreted …

Abstract Changes in atmospheric CO2 concentration have played a central role in algal and
plant adaptation and evolution. The commercially important red algal genus, Pyropia …

Earth was impacted by global glaciations during the Cryogenian (720 to 635 million years
ago; Ma), events invoked to explain both the origins of multicellularity in Archaeplastida and …

The long-held belief that animal-mediated pollination is absent in the sea has recently been
contradicted in seagrasses, motivating investigations of other marine phyla. This is …
