Název v původním jazyce
The Nature Of Aberrant Chromosomes In Apomictic Boechera Accessions
Popis výsledku v původním jazyce
The only apomicts in the Brassicaceae family reported so far were found in the genus Boechera and occur at the diploid, triploid and tetraploid level. Among the diploids cytotypes with 14 and 15 chromosome complements were found showing a plethora of different forms in chromosome morphology. Chromosome painting with genomic DNA of sexual B. stricta and B. holboellii (or related species) suggests that homoeologous chromosome substitution is common in these apomicts producing accessions with different chromosomes from their putative sexual ancestors. All apomicts studies so far display one or two aberrant chromosomes: a highly heterochromatic chromosome (Het) in the 14 and 15 chromosome accessions and a strikingly small chromosome (Del) in the 15 chromosome accessions. Here we report the analysis of chromosome painting experiments using pooled BACs from gene blocks defined in the sexual B. stricta. Our data showed that the Het chromosome is related to linkage group 1 (LG 1) of B.
