Figure 3: Segmental ancestry of selected Manihot accessions.

From: Sequencing wild and cultivated cassava and related species reveals extensive interspecific hybridization and genetic diversity

Figure 3

(a) Inferred ancestry of 18 admixed individuals determined from whole genome shotgun sequencing data. Orange indicates M. esculenta genotype (E/E); light blue indicates M. glaziovii (G/G); light green represents hybrid M. glaziovii/M. esculenta (G/E). Dark green or black indicates presence of a shared M. glaziovii haplotype proposed to be inherited from the Amani program (GA). Teal segments in MBRA 685 and MCOL 1468 on chromosome 2 behave anomalously and do not fit a model of M. glaziovii/M. esculenta admixture, but are likely hybrids of M. esculenta and another unknown Manihot species (E/U) (see b, or Supplementary Note 7). Light gray segments indicate no ancestry call could confidently be made. (b,c) Clustering of M. glaziovii and M. esculenta haplotypes in chromosome 1 from 30.1 to 32.6 Mb (b) and chromosome 1 from 22 to 23 Mb (c), showing haplotype sharing among six of seven African cassava varieties and among three South American cassava varieties, respectively. (d) Introgression plot, as in a, for accessions sequenced by GBS with 1% detected introgression or greater. Accessions are divided by population. The shared Amani haplotype appears enriched in the TMe and TMS populations.
