Geographic origin of Sol R gene collection and identified late blight R genes. A) The complete SolRgene collection is originating from 14 countries in South, Central and North America. B) So-far identified R genes that confer resistance to P. infestans originate mainly from mountain regions in Central and South America. C) Accessions that contain Rpi-vnt1 homologs are restricted to Argentina.
