Contrasting Patterns of Transposable Element and Satellite Distribution on Sex Chromosomes (XY1Y2) in the Dioecious Plant Rumex acetosa
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 DN...

is more common among the dicots than the monocots (Renner and Ricklefs, 1995). Dioecy is a breeding system that promotes cross-pollination in Poa is a large, diverse genus that belongs to the subplants. The transfer of this trait into economically important selfpollinated cereal crops would revolutionize the production of hybrids family Pooideae of the Poaceae. Several species are in these spec...
متن کاملCloning and characterization of dispersed repetitive DNA derived from microdissected sex chromosomes of Rumex acetosa.
Rumex acetosa is characterized by a multiple chromosome system (2n = 12 + XX for females, and 2n = 12 + XY1Y2 for males), in which sex is determined by the ratio between the number of X chromosomes and autosome sets. For a better understanding of the molecular structure and evolution of plant sex chromosomes, we have generated a sex chromosome specific library of R. acetosa by microdissection. ...
متن کاملDivergence in Defence against Herbivores between Males and Females of Dioecious Plant Species
Defensive traits may evolve differently between sexes in dioecious plant species. Our current understanding of this process hinges on a partial view of the evolution of resistance traits that may result in male-biased herbivory in dioecious populations. Here, we present a critical summary of the current state of the knowledge of herbivory in dioecious species and propose alternative evolutionar...
متن کاملThe origin and evolution of the variability in a Y-specific satellite-DNA of Rumex acetosa and its relatives.
In this paper, we analyze a satellite-DNA family, the RAYSI family, which is specific of the Y chromosomes of Rumex acetosa, a dioecious plant species with a multiple sex-chromosome system in which the females are XX and the males are XY(1)Y(2). Here, we demonstrate that this satellite DNA is common to other relatives of R. acetosa, including Rumex papillaris, Rumex intermedius, Rumex thyrsoide...
