Jumping Genes and Shrinking Genomes Probing the Evolution of
Eukaryotic Photosynthesis with Genomics

Summary
The advent of comparative genomics has revolutionized the study
of the origin and evolution of eukaryotes and their organelles.
Genomic analysis has revealed that the endosymbiosis that gave rise
to plastids the light-harvesting apparatus of photosynthetic
eukaryotes had a profound impact on the genetic composition of
the host, far beyond the contribution of cyanobacterial genes for
plastid-specific functions. Here I discuss recent advances in our
appreciation of the mosaic nature of the eukaryotic nuclear genome,
and the ongoing role endosymbiosis plays in shaping its content.
