Chromosome And Genome Evolution In Brassica

Popis výsledku v původním jazyce

The tribe Brassiceae and the genus Brassica are characterized by the wide diversity of chromosome numbers spanning the range from 2n=14 to 2n=120 (2n=16-38 in Brassica). Whereas relatively recent polyploidy events resulting in elevated chromosome numbers(2n=34, 36, 38) have been recognized in Brassica more than seventy decades ago, paleo- and mesopolyploidy events shaping the genome structure of bona fide diploid brassicas (2n=16, 18, 20) were revealed only recently. I will demonstrate how the genome evolution in the Brassiceae was driven by multiple paleopolyploidy events, the later tribe-specific whole-genome triplication (mesopolyploidy) followed by karyotype shuffling, and recent allopolyploidization. Due to conserved chromosome collinearity between brassicas and other crucifer species including Arabidopsis thaliana, tentative evolutionary scenarios of Brassica genome evolution can be reconstructed.
