DNA diversity in sex-linked and autosomal genes of the plant species Silene latifolia and Silene dioica.
The relatively recent origin of sex chromosomes in the plant genus Silene provides an opportunity to study the early stages of sex chromosome evolution and, potentially, to test between the different population genetic processes likely to operate in nonrecombining chromosomes such as Y chromosomes. We previously reported much lower nucleotide polymorphism in a Y-linked gene (SlY1) of the plant ...
متن کاملNucleotide diversity in Silene latifolia autosomal and sex-linked genes.
The plant Silene latifolia has separate sexes and sex chromosomes, and is of interest for studying the early stages of sex chromosome evolution, especially the evolution of non-recombining regions on the Y chromosome. Hitch-hiking processes associated with ongoing genetic degeneration of the non-recombining Y chromosome are predicted to reduce Y-linked genes' effective population sizes, and S. ...
متن کاملX Linkage of AP3A, a Homolog of the Y-Linked MADS-Box Gene AP3Y in Silene latifolia and S. dioica
BACKGROUND The duplication of autosomal genes onto the Y chromosome may be an important element in the evolution of sexual dimorphism. A previous cytological study reported on a putative example of such a duplication event in a dioecious tribe of Silene (Caryophyllaceae): it was inferred that the Y-linked MADS-box gene AP3Y originated from a duplication of the reportedly autosomal ortholog AP3A...
متن کاملA pseudoautosomal random amplified polymorphic DNA marker for the sex chromosomes of Silene dioica.
The segregation pattern of an 810-bp random amplified polymorphic DNA (RAPD) band in the F1 and backcross generations of a Silene dioica (L.) Clairv. family provides evidence that this molecular marker is located in the pseudoautosomal region (PAR) of the X and Y chromosomes. The marker was found through a combination of bulked segregant analysis (BSA) and RAPD techniques. Recombination rates b...
متن کاملDe novo transcriptome assembly of heavy metal tolerant Silene dioica
Silene dioica is a dioecious plant of the family Caryophyllaceae. In the present study, we used Illumina sequencing technology (MiSeq) to sequence, de novo assembly and annotate the transcriptomes of male and female copper tolerant S. dioica individuals. We sequenced the normalized mRNA of roots, shoots, flower buds and flowers for each sex. Raw reads of the transcriptome assembly project for S...
