ethods to track and verify the integrity of multiple disease
resistancegenes areneeded for crop improvement in light
of pathogen population changes. Diagnostic resistance gene
enrichment sequencing (dRenSeq) enables the high-confidence
identification and complete sequence validation of functional
resistance genes in crops. We have shown that the technology
can direct parental selection in breeding programs and confirms
transgene integrity in GM crops. Our study reveals a very
limited base of utilised resistances in major potato cultivars but
has identified additional and currently very effective resistances
in potato varieties that could be combined with the help of the
technology. To combine the most complementary resistances,
we can assess the diversity of pathogen populations through
a similar enrichment-sequencing based approached referred to
as PenSeq. The combination of dRenSeq and PenSeq enables,
for the first time, a comprehensive Pathogen/Crop coevolution
study on a global scale.
