-The locus //B<sub>5</sub> //, when introgressed into the susceptible 'Acala 44' background (Ac//B<sub>5</sub> //), conferred strong and broad-spectrum resistance to bacterial blight (Essenberg //et al//., 2023). Segregation patterns indicated that Ac//B<sub>5</sub> // is likely homozygous for resistance at two loci with partial dominance gene action, and two of the four copies of //B<sub>5</sub> // were required for effective resistance (Essenberg //et al.//, 2023). Contrary to expectations of gene-for-gene theory, Ac//B<sub>5</sub> // conferred high resistance toward isogenic strains of //Xanthomonas citri// pv. //malvacearum// carrying cloned avirulence genes //avrB4//, //avrb7//, //avrBIn//, //avrB101//, and //avrB102//, respectively, and weaker resistance toward the strain carrying cloned //avrb6// (Essenberg //et al.//, 2023).
