High-density genome-wide association mapping implicates an F-box encoding gene in Medicago truncatula resistance to Aphanomyces euteiches

The use of quantitative disease resistance (QDR) is a promising strategy for
promoting durable resistance to plant pathogens, but genes involved in QDR are largely
unknown. To identify genetic components and accelerate improvement of QDR in legumes
to the root pathogen Aphanomyces euteiches, we took advantage of both the recently
generated massive genomic data for Medicago truncatula and natural variation of this model
legume.
