In marine species, high dispersal is often associated with only mild genetic differentiation
over large spatial scales. Despite this generalization, there are numerous reasons for the …

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 …

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

The field of systematic biology has been revitalized and transformed during the last few
decades by the confluence of phylogenetic thinking with ready access to the tools of …

Sequence comparisons of genomes or expressed sequence tags (ESTs) from related
organisms provide insight into functional conservation and diversification. We compare the …

Charles Darwin proposed that evolution occurs primarily by natural selection, but this view
has been controversial from the beginning. Two of the major opposing views have been …

This valuable book thoroughly examines adaptive evolution at the DNA level while taking a
comprehensive look at the research being done in the area. It presents useful cases where …

The author offers an overview of pollen biology and biotechnology for students and
researchers in areas such as reproductive biology, biotechnology, aeropalynology, plant …

▪ Abstract Trans-species polymorphism (TSP) is the occurrence of similar alleles in related
species. Excluding instances in which the similarity arose by convergent evolution, TSP is …

Behaviors, morphologies, and genetic loci directly involved in reproduction have been
increasingly shown to be polymorphic within populations. Explaining how such variants are …
