Description
Yihang Yang and co-authors uncover how a helpful bacterium blocks the sexual mating that the sugarcane smut fungus needs to infect plants. Smut is among the most damaging sugarcane diseases worldwide. The fungus must mate to form the threads that invade the crop. A bacterial strain found earlier stops that mating, and the team hunted for the genes behind the block.
Random mutations pointed to a two-part gene switch that controls the effect. The switch turns on a newly found seven-gene cluster that makes the mating inhibitor. Removing the cluster gutted the bacterium's blocking power. Two nearby regulator genes also proved essential. The work maps the control network behind this natural crop protection.
