Cytogenetic and sequence alignment analysis of the four chloroplast DNA fragments localized on the centromeric regions of sex chromosomes. a FISH analysis of the four chloroplast DNA sequences. Arrowheads indicate the sites of chloroplast DNA probe hybridization (red). Bars = 10 μm; (b) Karyotypic analysis based on FISH results; (c) Enlarged sex chromosomes with FISH signals and BLAST analysis of these four chloroplast DNA sequences
