“…The X chromosome is the largest in male metaphase, but both Y chromosomes together are bigger than the X chromosome. Five satellites have been found in R. acetosa —RAYSI, RAYII, RAYSII (specific for Y 1 and Y 2 , Shibata et al 1999; Navajas-Pérez et al 2005b), RAE180 (Y 1 , Y 2 and one autosome, Shibata et al 2000), and RAE730 (autosomes, Shibata et al 2000). RAYSI and RAE180 are the main components of the Y heterochromatin (Shibata et al.…”

“…RAYSI and RAE180 are the main components of the Y heterochromatin (Shibata et al. 1999, 2000). RAYSI is also common in other species with multiple XY 1 Y 2 systems ( R. papillaris , R. intermedius , R. thyrsoides , and R. tuberosus ) but absent in species with an XY system such as R. acetosella and R. suffruticosus (Navajas-Pérez et al 2005b; Cunado et al 2007).…”

“…RAE180 is expanded on the Y 1 chromosome in R. acetosa . It is also amplified on one autosome in R. suffruticosus and dispersed in low copy number in R. acetosella (Shibata et al 2000; Cunado et al 2007; Navajas-Pérez et al 2009). RAYSI, RAYSII, RAYSIII, and RAE730 satellites arose by different ancestral duplications and reshufflings from the same 120-bp unit (Navajas-Pérez et al 2005b; Mariotti et al 2009).…”

Rumex acetosa is a dioecious plant with the XY1Y2 sex chromosome system. Both Y chromosomes are heterochromatic and are thought to be degenerated. We performed low-pass 454 sequencing and similarity-based clustering of male and female genomic 454 reads to identify and characterize major groups of R. acetosa repetitive DNA. We found that Copia and Gypsy retrotransposons dominated, followed by DNA transposons and nonlong terminal repeat retrotransposons. CRM and Tat/Ogre retrotransposons dominated the Gypsy superfamily, whereas Maximus/Sireviruses were most abundant among Copia retrotransposons. Only one Gypsy subfamily had accumulated on Y1 and Y2 chromosomes, whereas many retrotransposons were ubiquitous on autosomes and the X chromosome, but absent on Y1 and Y2 chromosomes, and others were depleted from the X chromosome. One group of CRM Gypsy was specifically localized to centromeres. We also found that majority of previously described satellites (RAYSI, RAYSII, RAYSIII, and RAE180) are accumulated on the Y chromosomes where we identified Y chromosome-specific variant of RAE180. We discovered two novel satellites—RA160 satellite dominating on the X chromosome and RA690 localized mostly on the Y1 chromosome. The expression pattern obtained from Illumina RNA sequencing showed that the expression of transposable elements is similar in leaves of both sexes and that satellites are also expressed. Contrasting patterns of transposable elements (TEs) and satellite localization on sex chromosomes in R. acetosa, where not only accumulation but also depletion of repetitive DNA was observed, suggest that a plethora of evolutionary processes can shape sex chromosomes.

Dioecious plants vary in whether their sex chromosomes are heteromorphic or homomorphic, but even homomorphic sex chromosomes may show divergence between homologues in the non-recombining, sex-determining region (SDR). Very little is known about the SDR of these species, which might represent particularly early stages of sex-chromosome evolution. Here, we assess the size and content of the SDR of the diploid dioecious herb Mercurialis annua, a species with homomorphic sex chromosomes and mild Y-chromosome degeneration. We used RNA sequencing (RNAseq) to identify new Y-linked markers for M. annua. Twelve of 24 transcripts showing male-specific expression in a previous experiment could be amplified by polymerase chain reaction (PCR) only from males, and are thus likely to be Y-linked. Analysis of genome-capture data from multiple populations of M. annua pointed to an additional six male-limited (and thus Y-linked) sequences. We used these markers to identify and sequence 17 sex-linked bacterial artificial chromosomes (BACs), which form 11 groups of non-overlapping sequences, covering a total sequence length of about 1.5 Mb. Content analysis of this region suggests that it is enriched for repeats, has low gene density, and contains few candidate sex-determining genes. The BACs map to a subset of the sex-linked region of the genetic map, which we estimate to be at least 14.5 Mb. This is substantially larger than estimates for other dioecious plants with homomorphic sex chromosomes, both in absolute terms and relative to their genome sizes. Our data provide a rare, high-resolution view of the homomorphic Y chromosome of a dioecious plant.

“…Several sex chromosome-derived sequences have been isolated in some dioecious flowering plants, e.g., S. latifolia (3)(4)(5)(6)(7), Cannabis sativa (8), and R. acetosa (9)(10)(11), that suggest a repetitive structure of sex chromosomes in plants. In S. latifolia, interspersed and localized repeat sequences were identified on the sex chromosomes by microdissection and degenerate oligonucleotide primed PCR (DOP-PCR; refs.…”

The haploid liverwort Marchantia polymorpha has heteromorphic sex chromosomes, an X chromosome in the female and a Y chromosome in the male. We here report on the repetitive structure of the liverwort Y chromosome through the analysis of male-specific P1-derived artificial chromosome (PAC) clones, pMM4G7 and pMM23-130F12. Several chromosome-specific sequence elements of Ϸ70 to 400 nt are combined into larger arrangements, which in turn are assembled into extensive Y chromosome-specific stretches. These repeat sequences contribute 2-3 Mb to the Y chromosome based on the observations of three different approaches: fluorescence in situ hybridization, dot blot hybridization, and the frequency of clones containing the repeat sequences in the genomic library. A novel Y chromosome-specific gene family was found embedded among these repeat sequences. This gene family encodes a putative protein with a RING finger motif and is expressed specifically in male sexual organs. To our knowledge, there have been no other reports for an active Y chromosome-specific gene in plants. The chromosome-specific repeat sequences possibly contribute to determining the identity of the Y chromosome in M. polymorpha as well as to maintaining genes required for male functions, as in mammals such as human.dioecism ͉ sex chromosome ͉ FISH ͉ RING finger motif ͉ convergent evolution
