Abstract
A decade of genome sequencing has transformed our understanding of how trypanosomatid parasites have evolved and provided fresh impetus to explaining the origins of parasitism in the Kinetoplastida. In this review, I will consider the many ways in which genome sequences have influenced our view of genomic reduction in trypanosomatids; how species-specific genes, and the genomic domains they occupy, have illuminated the innovations in trypanosomatid genomes; and how comparative genomics has exposed the molecular mechanisms responsible for innovation and adaptation to a parasitic lifestyle.
Highlights
Trypanosomatids are unicellular flagellates and obligate parasites that infect various animals and plants
Other species of Trypanosoma and Leishmania infect a wide range of vertebrate hosts, and all are transmitted by invertebrate vectors; predominantly these are biting insects, some aquatic species are transmitted by leeches (Lom, 1979)
In Trypanosoma, the 5′-most copy of a cation transporter gene array is preferentially expressed in the procyclic form (PCF) (Jensen et al 2009; Urbaniak et al 2012), while transcripts for all downstream copies are up-regulated in the bloodstream stage (Jensen et al 2009; Veitch et al 2010)
