How an organelle evolves

A team of biologists has found that the endosymbionts of Strigomonadinae have lost virtually all genes required for division, instead relying on a nucleus-encoded protein to control their movement. This discovery provides insights into the evolution of organelles from bacteria and could lead to the development of synthetic symbiosis.
