Resurrect Bio is a plant biotech start-up, based in London. We will improve the immune system of crop species. Climate change is causing diseases to spreading to new locations, meaning the disease spectrum farmers are dealing with is expanding. Crops were bred over generations by plant breeders to improve key traits such as yield, height or drought-tolerance, but sometimes inadvertently lost key immune resistance genes (R-genes). Additionally, modern monocultures are static in evolution, but the pests and pathogens that threaten them are not. Plant diseases are constantly evolving new ways of defeating the R-genes in crops.
