Rum1 and Cdc73 integrate transcriptional repression and autophagy to control teliospore timing in Ustilago maydis.

In the biotrophic smut fungus Ustilago maydis, teliospore formation depends on mating and host cues, but the mechanisms that restrain this program during vegetative growth remain unclear. We show that loss of the conserved PAF1 complex subunit UmCdc73 triggers spontaneous teliospore-like differentiation under axenic co...
