The evolution of self-compatibility and its genetic consequences in Leavenworthia alabamica (Brassicaceae)
The evolution of self-fertilization from the outcrossing condition is a common transition in flowering plants which strongly alters the genetic structure of populations. In general, it is thought that self-fertilization may evolve in response to its innate transmission advantage or pollen …

Identification Of Candidate Genes For Self-Compatibility In A Diploid Population Of Potato Derived From Parents Used In Genome Sequencing
Gametophytic self-incompatibility limits the ability to derive inbred lines of potato through self-pollination and is prevalent in diploid potato. Within a population of F1 hybrids between two genotypes used in potato genome sequencing, we observed fruit set on many greenhouse-grown plants. …

The evolution and prevalence of reproductive assurance in the genus Lachenalia
… can arise in a multitude of manners, and RA itself takes many forms. Here its evolution and prevalence in the genus Lachenalia (Asparagaceae) is investigated. The genus exhibits many of the characteristics suggested in the literature to be associated with reproductive assurance, including …

Molecular phylogenetics, systematics, reproductive safeguarding and chromosome evolution of the genus Lachenalia (Asparagaceae: Scilloideae)
… evolution of reproductive safeguarding traits (self compatibility, autonomous selfing, bird pollination and clonal propagation) in low insect abundance contexts (i.e., infertile fynbos heathland, and species which flower outside of the austral spring season). Ancestral state reconstructions …

The reproductive biology of Clematis addisonii
… biology of this species reveals that it is self-compatible, showing no significant reduction in fecundity following self-pollinations. Morphological observations indicate that this species is protogynous. <i>In vivo</i> pollen tube growth supports this conclusion. Field observations suggest …

Moth pollination, low seed set, and vestigialization of attractive floral traits in Abronia umbellata (Nyctaginaceae)
… outcross siring success. The transition from self-incompatibility and obligate outcrossing to self-compatibility and predominant selfing is the most common evolutionary transition among the flowering plants and traits associated with outcrossing may become reduced across such shifts, …

Self-incompatibility in Cosmos atrosanauineus: a rare Mexican endemic species of Asteraceae
… on Cosmos atrosanguineus, a rare Mexican endemic self-incompatible species of Asteraceae that is now believed to be extinct in the wild. The two known wild C. atrosanguineus collections, made in made in the 19th century, localise the species to the pine-oak mountain forest ecological region in two …

Evolutionary dynamics of mating systems in populations of North American Arabidopsis lyrata
… outcrossing perennial due to a sporophytic self incompatibility (SI) system. The species occurs in temperate regions of the Northern hemisphere where in Europe its SI system is fully working but around the Great Lakes of North America some populations of A. lyrata show a breakdown in SI. …
