Abstract

Most sexual organisms ensure that organelles are inherited from a single parent. Here, the authors describe OTU2p, a Chlamydomonas deubiquitinase that drives uniparental organelle inheritance without gametic dimorphism by preventing proteasome-mediated degradation exclusively in gametes of the plus mating type.
