Grapevine

IGA focuses on three loci controlling downy or powdery mildew resistance: Rpv3, Rpv12, Ren1. Ren1 is the first resistance gene that naturally evolved functional specificity against powdery mildew in the cultivated species Vitis vinifera. Rpv3 and Rpv12 were originally present in undomesticated grapes in North America and Asia and were historically used in introgression breeding.

Olive

IGA is collaborating with the Institute of Biosciences and Bioresources of the National Research Council (CNR-IBBR) in Perugia (Italy) for studying the locus responsible for self-incompatibility in olive cultivars. We mapped the locus on olive chromosome 18 and developed a DNA marker for a rapid screening of inter-compatibility in olive germplasm.
