Mapping an avirulence gene in the sunflower parasitic weed Orobanche cumana and characterization of host selection based on virulence alleles
This study mapped for the first time an avirulence gene in parasitic plants using a classical genetic approach, confirmed a gene-for-gene model in the O.cumana -sunflower system, and showed the implication of this single avirulence gene in determining the structure of broomrape populations subjected to selection pressure posed by a resistant genotype. The results will contribute to a better understanding of the interaction between crops and weedy parasitic plants, and to effectively manage evolution of virulence by sustainable control strategies based on host genetic resistance.
