Single cell genomics reveals plastid-lacking Picozoa are close relatives of red algae
Abstract
The origin of primary plastids in an ancestor of Archaeplastida gave eukaryotes photosynthetic capabilities. This study used single-cell genomics and phylogenomics to infer the evolutionary origin of the plastid-lacking phylum Picozoa, a group of marine microbial heterotrophic eukaryotes, showing that they belong to the Archaeplastida and changing our understanding of plastid evolution.
