Since Darwinian times considerable knowledge has accumulated on the distribution,
physiology and genetics of self-incompatibility (SI) in higher plants. In the second half of this …

Heterostylous genetic polymorphisms provide paradigmatic systems for investigating
adaptation and natural selection. Populations are usually comprised of two (distyly) or three …

Since the first edition of this book published in 2005, there has been an immense amount of
new and fascinating work on the history, ecology, and evolution of the Mediterranean flora …

Advances in plant cell molecular biology have considerably increased our understanding of
pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the …

Comparisons of the causes and consequences of cross–and self–fertilization have
dominated research on plant mating since Darwin's seminal work on plant reproduction …

HERMAPHRODITISM comprises outcrossing whenever the proximity of male and female
organs allows self-fertilization1 and interference between sexual functions2. Many floral …

Supergenes are genomic regions containing sets of tightly linked loci that control multi-trait
phenotypic polymorphisms under balancing selection. Recent advances in genomics have …

Breeding systems are important, and often neglected, aspects of the natural biology of
organisms, affecting homozygosity and thus many aspects of their biology, including levels …

We are in the midst of a biological revolution. Molecular tools are now providing new means
of critically testing hypotheses and models of microevolution in populations of wild …

Darwin's studies on heterostyly in Primula described two floral morphs, pin and thrum, with
reciprocal anther and stigma heights that promote insect-mediated cross-pollination. This …
