The establishment and application of specific molecular markers to detect bacterial wilt resistance gene in tomato.

Fig. 1. TILLING was used to explore SNPs in the target segment. Four InDel markers (TM12012, TM12105, TM12059, and TM12-10#10) and 6 SCAR markers were developed and screened. The stability of the primers was tested by different tomato materials, and all the bands of resistant and susceptible genotypes were stably amplified.

Fig. 2 The markers developed in this study for tomato bacterial wilt resistance gene Bwr-12 were marked on the their relevant positions on the GeneBank HG975224.1 sequence from the NCBI database. The association between the genotypes of the markers and the phenotypes were evaluated by 36 susceptible plants and 157 non-infected plants. The marker, TM12-1107, which has the highest association could replace the reference primers to detect the resistance gene.
