Pyramiding Recessive Resistance Genes Enhances Bacterial Leaf Spot Resistance in Peppers by Suppressing <i>In Planta</i> Bacterial Growth.

ABSTRACT: Bacterial spot of the pepper (BSP) and the tomato (BST) caused by multiple Xanthomonas spp. remains a major constraint to production of both crops worldwide. The widespread breakdown of dominant resistance genes, such as Bs2, due to the emergence of virulent races, like Xanthomonas euvesicatoria P6, has underscored the need for more durable, non-race-specific resistance. The recessive genes, bs5; bs6; and bs8, have emerged as promising alternatives, conferring broad-spectrum resistance without triggering a hypersensitive response. In this study, we systematically evaluated the individual and combinatorial effects of these three recessive resistance genes against three Xanthomonas species, X. euvesicatoria (Xe), X. hortorum</
