| soluble inorganic tissue phosphorus and calcicole-calcifuge behaviour of plants. | natural and semi-natural, non-fertilized calcareous soils are consistently low in soluble and easily exchangeable phosphate. an over-utilization, or possibly an immobilization, of inorganic p in the tissues of calcifuge plants may take place, if such plants are forced to grow on a calcareous soil, though this has not been experimentally demonstrated. the objectives of this study are, therefore, to elucidate if calcifuge plants, when forced to develop on a calcareous soil, not only have lower tot ... | 2004 | 15277247 |
| microbotryum heliospermae, a new anther smut fungus parasitic on heliosperma pusillum in the mountains of the european alpine system. | the members of the smut genus microbotryum are pathogens of a wide range of host plant species from nine dicotyledonous families. within the genus, the species sporulating in anthers of caryophyllaceae form a monophyletic group that in recent years attracted much interest in various biological studies. the phylogenetic framework developed for species delimitation within microbotryum revealed that high level host-specificity is a major feature of most caryophyllaceous anther smuts. however, the g ... | 2011 | 22289764 |
| an aflp clock for the absolute dating of shallow-time evolutionary history based on the intraspecific divergence of southwestern european alpine plant species. | the dating of recent events in the history of organisms needs divergence rates based on molecular fingerprint markers. here, we used amplified fragment length polymorphisms (aflps) of three distantly related alpine plant species co-occurring in the spanish sierra nevada, the pyrenees and the southwestern alps/massif central to establish divergence rates. within each of these species (gentiana alpina, kernera saxatilis and silene rupestris), we found that the degree of aflp divergence (d(n72)) be ... | 2009 | 19175503 |
| long-distance dispersal vs vicariance: the origin and genetic diversity of alpine plants in the spanish sierra nevada. | here, we investigated the origin and genetic diversity of four alpine plant species co-occurring in the spanish sierra nevada and other high mountains in south-western europe by analysis of amplified fragment length polymorphisms (aflps). in kernera saxatilis, silene rupestris and gentiana alpina we found intraspecific phylogroups corresponding to mountain regions as predicted by the vicariance hypothesis. moreover, genetic distances between sierra nevada and pyrenees populations were always hig ... | 2006 | 16945099 |
