| dc.description.abstract-translated | Previous studies have shown a dynamic karyotype evolution and the presence of complex sex chromosome systems with 3-4 W chromosomes and 3-6 Z chromosomes in Leptidea wood white butterflies. To dissect the evolutionary history of multiple Z chromosomes of Leptidea species, we used identified and selected bacterial artificial chromosome (BAC) clones containing orthologous genes of Bombyx mori chromosome Z and 17, isolated them from the available BAC library and used them as probes for physical mapping by BAC-FISH, first in L. juvernica, then in the closely related L. sinapis. In both Leptidea species, the majority of BAC clones corresponding to the linkage group Z of the B. mori reference genome hybridized to one chromosome of the complicated sex chromosome multivalent. Thus, we named it as Z1 chromosome. Location of all Z-derived BAC clones was identical in both species suggesting a conserved synteny and gene order between L. juvernica and L. sinapis Z1 chromosome. Moreover, our findings indicate that the Z1 chromosome is probably the ancestral Z chromosome in the genus Leptidea. Results of BAC-FISH mapping with clones corresponding to the linkage group 17 of the B. mori reference genome revealed the fusion/translocation event between an ancestral Z chromosome and the chromosome corresponding to B. mori chromosome 17 and supported a previous hypothesis about the role of chromosomal rearrangements in the formation of multiple sex chromosomes in Leptidea butterflies. | eng |
