Silene latifolia is a model dioecious plant with morphologically distinguishable XY sex chromosomes. The end of the Xq arm is quite different from that of the Yp arm, although both are located at opposite ends of their respective chromosomes relative to a pseudo-autosomal region. The Xq arm does not seem to originate from the same autosome as the Yp arm. Bacterial artificial chromosome clone #15B12 has an insert containing a 130-kb stretch in which a 313-bp satellite DNA is repeated 420 times. PCR with a single primer revealed that this 130-kb stretch consists of three reversals of the orientation of the satellite DNA. A non-long terminal repeat retroelement and two sequences that share homology with an Oryza sativa RING zinc finger and a putative Arabidopsis thaliana protein, respectively, were found in the sequences that flank the satellite DNA. Fluorescence in situ hybridization carried out using this low-copy region of #15B12 as a probe confirmed that these sequences originated from the X chromosome and that homologous sequences exist at the end of chromosome 7. The region distal to DD44X on the Xq arm is postulated to have recombined with a region containing satellite DNA on chromosome 7 during the process of sex chromosome evolution.

Conserved domains of two types of LTR retrotransposons, Ty1–copia- and Ty3–gypsy-like retrotransposons, were isolated from the dioecious plant Silene latifolia, whose sex is determined by X and Y chromosomes. Southern hybridization analyses using these retrotransposons as probes resulted in identical patterns from male and female genomes. Fluorescence in situ hybridization indicated that these retrotransposons do not accumulate specifically in the sex chromosomes. These results suggest that recombination between the sex chromosomes of S. latifolia has not been severely reduced. Conserved reverse transcriptase regions of Ty1–copia-like retrotransposons were isolated from 13 different Silene species and classified into two major families. Their categorization suggests that parallel divergence of the Ty1–copia-like retrotransposons occurred during the differentiation of Silene species. Most functional retrotransposons from three dioecious species, S. latifolia, S. dioica, and S. diclinis, fell into two clusters. The evolutionary dynamics of retrotransposons implies that, in the genus Silene, dioecious species evolved recently from gynodioecious species.Key words: retrotransposon, dioecious plant, sex chromosome.
