A dominant mutation in tomato DNA POLYMERASE DELTA 1 causes geminivirus DNA replication catastrophe.

Proceedings of the National Academy of Sciences of the United States of America - 1 Sept 2026

Abstract excerpt

Geminiviruses pose a severe threat to grain and vegetable crops worldwide, often resulting in significant economic losses. In cultivated tomato (Solanum lycopersicum), Ty resistance alleles have been introduced from wild tomato relatives, providing partial to strong resistance to geminivirus infections. The Ty-6 resistance locus from Solanum chilense was previously mapped to chromosome 10. It was recently shown...
