The Common Ancestral Genome of the Brassica Species
Original language description
All Brassica species are derived from a common hexaploid ancestor, and this hexaploid ancestor has been further deduced to origin from a diploid species through a whole genome triplication event. The diploid ancestor has 7 chromosomes and resembles the karyotype of tPCK (translocation Proto-Calepineae Karyotype). The confirming evidences for the Brassicas? tPCK ancestor are from below three aspects: (1) The reconstructed genomic segments of the three subgenomes of all Brassica species keep the genomic structure of tPCK; (2) The locations of extant centromeres and the traces of paleocentromeres on the genomes of Brassicas support its ancestral diploid genome as tPCK; (3) The phylogeny tree and evolution analysis based on the whole genome sequences of several sequenced Brassicaceae species find that the Brassicas are evolved from a tPCK genome, such as the tPCK species S. parvula.
