   Sammanfattning : Self-incompatibility (SI) is a genetic mechanism that allows plants to enforce outcrossing by rejecting self-pollen and pollen from close relatives. In the Brassicaceae, SI is sporophytic and controlled by the self-incompatibility locus (S-locus). LÄS MER

   Sammanfattning : Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. LÄS MER
