Research Abstract

To analyze the size difference between large (L-type) and small (S-type) chromosome sets in Aster, FISH with new screened DNA sequences from L-type parental genome was performed. An insight obtained from the result suggested that the new DNA sequences were involved in the chromosome size change.
