A natural gene drive system confers reproductive isolation in rice

Background

  • DUYAO-JIEYAO encodes a toxin-antidote system that confers hybrid male sterility
  • DUYAO interacts with OsCOX11 to trigger mitochondrial malfunction and cytotoxicity
  • JIEYAO detoxifies DUYAO by rerouting DUYAO to the autophagosome for degradation
  • DUYAO-JIEYAO forms a natural gene drive system that may promote speciation in rice

Such a natural gene drive could be engineered to reduce female mosquito transmitted diseases in humans by generating homozygous sterile female mosquitos or male-only populations. Indeed, it will be exciting to see such a system fully exploited for biotechnology and biomedical purposes.
