Genetic mapping of the NtTOM2A_T homeolog by bulked segregant analysis and map-based cloning. a, b Diagrammatic sketch of the bulked segregant analysis used in this research. P1: K326, P2: JT88. Numbers 0, 1, 3, 5, 7, and 9 represent the disease grade from the lowest to the highest. R bulk: resistant bulk, S bulk: susceptible bulk. Frequency: the corresponding amounts of different disease grade individual plants. c Genetic mapping of the NtTOM2A_T homeolog. Manhattan plot of the bulked segregant analysis was used for fine mapping the NtTOM2A_T homeolog, which was mapped to a 2.42 Mb region between SNP-2 and SNP-5 on chromosome Hic_asm_21 based on the crossover rate. This region contains 53 predicted genes
