Fig. 1From: Use of genotyping-by-sequencing to determine the genetic structure in the medicinal plant chamomile, and to identify flowering time and alpha-bisabolol associated SNP-loci by genome-wide association mappingPhylogenetic tree of M recutita samples calculated with the neighbor-joining method. The tree derived from the supermatrix consisting of all concatenated sequences and was rooted with the outgroup M. discoidea (MD1 and 701). The long branch leading to the outgroup was arbitrarily shortened for clarity. Bootstrap values (bs) of the clades above 75 are indicated close to the nodesBack to article page
