Evolution of metabolic capabilities and molecular features of diplonemids, kinetoplastids, and euglenids.

ABSTRACT:

Background

The Euglenozoa are a protist group with an especially rich history of evolutionary diversity. They include diplonemids, representing arguably the most species-rich clade of marine planktonic eukaryotes; trypanosomatids, which are notorious parasites of medical and veterinary importance; and free-living euglenids. These different lifestyles, and particularly the transition from free-living to parasitic, likely require different metabolic capabilities. We carried out a comparative genomic analysis across euglenozoan diversity to see how changing repertoires of enzymes and structural features correspond to major changes in lifestyles.

Results

We find a gradual loss of genes encoding enzymes in the evolution of kinetoplastids, rather than a sudden decrease in metaboli
