Abstract

Chromalveolates include photosynthetic and nonphotosynthetic (some plastid-lacking) algae and protists that define a vast swath of eukaryotic diversity. These taxa are masters of gene acquisition through serial endosymbiosis (endosymbiotic gene transfer, EGT) and horizontal gene transfer (HGT). Understanding the contribution of these sources to nuclear genomes is key to elucidating chromalveolate evolution and to identifying suitable phylogenetic markers to place this lineage in the tree of life. Here we briefly review recent findings in our lab with regard to EGT and HGT in chromalveolates.
