Karyotype evolution in apomictic Boechera and the origin of the aberrant chromosomes

Original language description

Chromosome rearrangements may result in both decrease and increase of chromosome numbers. Here we have used comparative chromosome painting (CCP) to reconstruct the pathways of descending and ascending dysploidy in the genus Boechera (tribe Boechereae, Brassicaceae). We describe the origin and structure of three Boechera genomes and establish the origin of the previously described aberrant Het and Del chromosomes found in Boechera apomicts with euploid (2n=14) and aneuploid (2n=15) chromosome number. CCP analysis allowed us to reconstruct the origin of seven chromosomes in sexual B.stricta and apomictic B.divaricarpa from the ancestral karyotype (n=8) of Brassicaceae lineage I. Whereas three chromosomes (BS4, BS6, and BS7) retained their ancestral structure, five chromosomes were reshuffled by reciprocal translocations to form chromosomes BS1-BS3 and BS5. The reduction of the chromosome number (from x=8 to x=7) was accomplished through the inactivation of a paleocentromere on chromosom
