Fine-mapping of the leaf rust Lr34 locus in Triticum aestivum (L.) and characterization of large germplasm collections support the ABC transporter as essential for gene function.

Abstract excerpt

Leaf rust resistance gene Lr34 is likely the most important leaf rust gene characterized to date. It has been characterized as an adult plant resistance gene and is known to enhance the resistance of other leaf rust resistance genes and to condition resistance to a number of other diseases. Located on chromosome 7D, this gene was identified to be one of six co-located genes of which, an ABC transporter was shown...
