We sequenced the genomes of three Orobanche species with different host ranges: O. minor (generalist), O. gracilis (Fabaceae-specific), and O. hederae (ivy-specific with some flexibility within Araliaceae). O. gracilis showed expanded protein-degrading and carbohydrate-active enzyme families, while putative strigolactone receptor (KAI2d) numbers varied from five in specialists to eleven in the generalist O. minor.
