Perplexing dynamics of Wolbachia proteins for cytoplasmic incompatibility.

ABSTRACT

The mechanism of symbiont-induced cytoplasmic incompatibility (CI) has been a long-standing mystery. A new study on Wolbachia's Cif proteins in PLOS Biology provides supportive evidence for the "Host modification model," although the alternative "Toxin-antidote model" is still in the running.
