Introgressive Hybridization between Anciently Diverged Lineages of Silene (Caryophyllaceae)
Hybridization has played a major role during the evolution of angiosperms, mediating both gene flow between already distinct species and the formation of new species. Newly formed hybrids between distantly related taxa are often sterile. For this reason, interspecific crosses resulting in fertile hybrids have rarely been described to take place after more than a few million years after divergen...
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 ...

This book is a collection of the thirteenth series of the Laity Lectures of the New York Academy of Medicine. Delivered for the benefit of those interested in the medical and teaching professions and also in the related fields of social service and public health, the essays have a common theme which emphasizes the interrelationship of medical research with the public and its elected representat...
متن کاملBidirectional Introgressive Hybridization between a Cattle and Human Schistosome Species
Schistosomiasis is a disease of great medical and veterinary importance in tropical and subtropical regions, caused by parasitic flatworms of the genus Schistosoma (subclass Digenea). Following major water development schemes in the 1980s, schistosomiasis has become an important parasitic disease of children living in the Senegal River Basin (SRB). During molecular parasitological surveys, nucl...
متن کاملCharacterization of 14 microsatellite markers for Silene acaulis (Caryophyllaceae)1
PREMISE OF THE STUDY Fifty candidate microsatellite markers, generated using 454 shotgun sequencing, were tested for the widespread arctic/alpine herb Silene acaulis (Caryophyllaceae). METHODS AND RESULTS Fourteen out of 50 markers resulted in polymorphic products with profiles that enabled interpretation. The numbers of alleles per locus ranged from two to six, and the expected heterozygosit...
