Coordinated immune, chloroplast and chemical defences underpin multilayered resistance to barley yellow dwarf virus and its aphid vector associated with the Hordeum bulbosum-derived Ryd4 introgression in barley
It is demonstrated that the Ryd4 introgression coordinates constitutive vector deterrence with host defence reprogramming to restrict aphid colonisation and suppress BYDV establishment, providing a mechanistic framework for improving durable resistance to aphid-transmitted viruses in cereals.
