Mapping of two SNP markers, Xm5511 and Xm564, on chromosomes 3B and 4B and comparison with known locations of HKT1;5 genes in wheat. Both homoeologous genes in genomes A and D have similar genetic locations along the corresponding chromosomes. HKT1;5-A (Nax2) has been mapped onto the distal part of chromosome 5A with an estimated genetic distance of about 17 cM from the end of chromosome 5AL [15]. Part of chromosome 5AL originated from part of chromosome 4AL due to an ancient reciprocal translocation between the distal ends of chromosomes 4AL and 5AL [23]. HKT1;5-D (Kna1) has been identified in the genetic region about 14% from the end of chromosome 4DL [20]. Two genes; HKT1;5-B1 and HKT1;5-B2 on chromosome 4BL. HKT1;5-B1 is very close to the locus of Xm564 which is 17 cM from the end of chromosome 4BL, HKT1;5-B2 sits closer to the centromere on this chromosome
