There are two general types of resistance genes found in wheat: Race - specific genes confer a high - level of resistance to specific strains of leaf rust but can be easily
overcome by genetic mutation in pathogen populations, while slow rusting (APR) resistance provides partial resistance to a broad spectrum of races, but is typically effective only at the adult stage of plant growth.
A new study in The Journal of Molecular Diagnostics describes a multi-method strategy to
overcome existing technological limitations
by more accurately identifying PMS2 gene
mutations, which will improve diagnosis and support appropriate
genetic counseling and medical management.
