Abstract [en]

One of the challenges of evolutionary biologists is to reconstruct phylogenies, which are essential in order to understand the mechanisms of evolution. In systematic research, often only very small portions of the total genome are analyzed and assumed to reflect the species phylogeny. In principle, however, the resulting phylogenies do not reflect the history of the species, but rather the history of the individual DNA regions themselves. Sometimes the phylogenies show incongruences when based on different genomes, different genes, different copies of a gene, or different parts of a gene. These conflicts can either reflect complex phylogenetic patterns, or simply highlight errors and problems in lab procedures and/or phylogenetic methods. An example of a plant taxon with cases of conflicting gene phylogenies is Sileneae DC. (Caryophyllaceae). Silene section Elisanthe contains dioecious taxa with a X/Y chromosome system similar to that in humans. In order to understand the evolution of dioecy in Silene section Elisanthe, we compare the dioeciuos taxa with their closest relatives, using several molecular markers. We also test the utility of the potentially useful low-copy nuclear gene SlX1/SlY1, and its homologues in hermaphroditic taxa. We discovered that Elisanthe change places in the phylogenetic trees based on different parts of the SlX1/SlY1 alignment. We show that this may indicate that recombination between phylogenetically distant SlX1/SlY1 lineages has taken place.

Abstract [en]

The aim of this project is to provide a phylogenetic/taxonomic framework for the evolution of dioecy within Silene (Caryophyllaceae). There are several dioecious taxa within the genus, traditionally classified in the sections Elisanthe and Otites. To understand how dioecy has evolved, these dioecious taxa need to be compared with their closest relatives. Available data suggest that the dioecious taxa within Elisanthe do not form a monophyletic group with the hermaphrodites in the section. Instead they seem more related to section Conoimorpha. This study is based on data from several Silene genes: (i) a gene sex-linked in the dioecious Elisanthe species (SlXY1) and a homologous autosomal gene in hermaphroditic taxa, (ii) intron sequences from the genes encoding the second largest subunits in the RNA polymerase gene family (RPA2, RPB2, RPD2) and (iii) chloroplast DNA. Remarkably, preliminary data suggest recombination between phylogenetically distant SIXY1 lineages.
