Abstract

Maize rough dwarf disease threatens its production. Here, the authors show that a helitron transposon insertion in the Rab GDP dissociation inhibitor alpha leads to recessive viral resistance by affecting its interaction with viral P7-1 protein and that all naturally occurring alleles come from a single mutation event after domestication.
