Molecular diversity in the genus Amaranthus
ond, intermediately related cluster, while A. albus, A. blitoides, A. gracilis, A. tricolor
and A. viridis (all tertiary genepool) can be found in the third, most distant cluster. Overall,
a rather clear subclustering according to taxonomy can be observed (indicated by
the different shades of grey for the mainly single-species clusters), which is also well
supported by the bootstrapping values (not shown). In this context, species designations
of probably three accessions have to be revised (AMA152, B-AMA06, B-AMA15; cf.
Figure 1/Table 1).
