Dissection of floral pollination syndromes in Petunia.
Animal-mediated pollination is essential in the reproductive biology of many flowering plants and tends to be associated with pollination syndromes, sets of floral traits that are adapted to particular groups of pollinators. The complexity and functional convergence of various traits within pollination syndromes are outstanding examples of biological adaptation, raising questions about their me...
متن کاملTight Genetic Linkage of Prezygotic Barrier Loci Creates a Multifunctional Speciation Island in Petunia
Most flowering plants depend on animal vectors for pollination and seed dispersal. Differential pollinator preferences lead to premating isolation and thus reduced gene flow between interbreeding plant populations. Sets of floral traits, adapted to attract specific pollinator guilds, are called pollination syndromes. Shifts in pollination syndromes have occurred surprisingly frequently, conside...
متن کاملPetunia as a Model System for the Genetics and Evolution of Pollination Syndromes
In recent years Petunia has become a promising model system for studying the genetics and evolution of pollination syndromes. Here we provide a brief introduction to the issue of pollination syndromes, explain why Petunia is a suitable model for its study, present useful background information about pollinators and plants, review recent studies, and discuss questions related to the genetics and...
متن کاملAsymmetric effects of loss and gain of a floral trait on pollinator preference.
Shifts in pollination syndromes involve coordinated changes in multiple floral traits. This raises the question of how plants can cope with rapid changes in pollinator availability by the slow process of accumulation of mutations in multiple genes. Here we study the transition from bee to hawkmoth pollination in the genus Petunia. Interspecific crosses followed by single locus introgressions we...
متن کاملSpeciation genes in the genus Petunia.
A major innovation in angiosperms is the recruitment of animal pollinators as a means to enhance the efficiency and specificity of pollen transfer. The implementation of this reproductive strategy involved the rapid and presumably coordinated evolution of multiple floral traits. A major question concerns the molecular identity of the genetic polymorphisms that specify the phenotypic differences...
