From: Association mapping and marker-assisted selection of the lettuce dieback resistance gene Tvr1
Sequence comparison of the four haplotypes detected at marker Cntg10192. Three haplotypes (R1, R2, & R3) are associated with dieback resistance while the S1 haplotype is always associated with susceptibility to the disease. Horizontal arrows indicate positions of the primers used for sequencing and for the HRM analysis. Asterisks show the positions of the three SNPs present in the marker.
