Glacial Refugia in Pathogens: European Genetic Structure of Anther Smut Pathogens on Silene latifolia and Silene dioica
Climate warming is predicted to increase the frequency of invasions by pathogens and to cause the large-scale redistribution of native host species, with dramatic consequences on the health of domesticated and wild populations of plants and animals. The study of historic range shifts in response to climate change, such as during interglacial cycles, can help in the prediction of the routes and ...
متن کاملHistory of the invasion of the anther smut pathogen on Silene latifolia in North America.
Understanding the routes of pathogen introduction contributes greatly to efforts to protect against future disease emergence. Here, we investigated the history of the invasion in North America by the fungal pathogen Microbotryum lychnidis-dioicae, which causes the anther smut disease on the white campion Silene latifolia. This system is a well-studied model in evolutionary biology and ecology o...
متن کاملin Silene latifolia (Caryophyllaceae)
• Sex ratio polymorphism has been extensively studied in Silene latifolia, but it is neither known whether inbreeding (which is likely to occur under field conditions) affects it nor which of the proposed mechanisms (Y degeneration, X-linked drive) is more important. Both mechanisms predict reduced pollen performance. • In this study, females were crossed with pollen from related and unrelated ...
متن کاملDNA 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 کاملTissue Culture and Quantification of Individual-level Resistance to Anther-smut Disease in Silene Vulgaris
Resistance to systemic diseases is often difficult to measure quantitatively because individuals can be scored only as either diseased or healthy. A technique is described for cloning individuals of Silene vulgaris plants using the tissue culture of seedling meristems. Inoculation of such clonally replicated genotypes within two families shows that segregation of resistance to anther-smut disea...
