Although much is known about the genetic basis of reproductive isolation between species, little is understood about its underlying evolutionary causes. A study of two very closely related, but reproductively isolated, plant species has provided some valuable insights. 

Figures and Tables from this paper

Multiple factors contribute to reproductive isolation between two co-existing Habenaria species (Orchidaceae)
TLDR
The results illustrate the reproductive isolation between two species involves multiple plant life-history stages and a variety of reproductive barriers can contribute to overall isolation. Expand
Ecology meets molecular genetics in Arabidopsis
TLDR
Arabidopsis thaliana has been used as a model plant for molecular genetics studies, and natural variations of various aspects are now available via the taxonomic revision of its closely related species, and by the worldwide collection of accessions. Expand
Strength, diversity and plasticity of postmating reproductive barriers between two hybridizing oak species (Quercus robur L. and Quercus petraea (Matt) Liebl.)
TLDR
It is shown that most traits exhibited important genotypic differences, as well as different levels of sensitivity to micro‐environmental heterogeneity, which suggest a large potential genetic diversity and plasticity of reproductive barriers. Expand
Resource allocation among sexual, clonal reproduction and vegetative growth of two Potamogeton species and their hybrid: Adaptability of the hybrid in relation to its parents
TLDR
Investigation of the resource allocation pattern of the first generation of the natural hybrid Potamogeton was indicated that the F1 hybrid P. ×intortifolius was more able to adapt to limiting environments than one or both of its two parental taxa. Expand
Pollination patterns limit hybridization between two sympatric species of Narcissus (Amaryllidaceae).
TLDR
Temporal displacement of flowering peaks, strong pollinator specificity, and high flower constancy in the shared pollinator all contributed to limiting hybridization in this site, which suggests different phenological windows and pollination assemblages may allow greater frequency of the hybrid. Expand
When interspecific prezygotic barriers break down: hybridization between two Potamogeton species (P. wrightii and P. perfoliatus) and comparison of the artificial and natural hybrids
TLDR
This is the most successful attempt at artificial hybridization in this genus so far and the possible route for restoration of fertility and the fitness of the hybrids are also discussed in this paper. Expand
Pre-zygotic reproductive isolation between two synchronopatric Opuntia (Cactaceae) species in the Brazilian Chaco.
TLDR
It is found that both Opuntia elata and O. retrorsa are closely related; however, they are isolated and do not hybridize in Brazilian Chaco, and both have weak pre-pollination barriers, but that they are strongly isolated by pollen-pistil incompatibility, i.e., post- pollination barrier. Expand
Reproductive isolation in four populations of the striped mouse Rhabdomys
TLDR
The results of the behavioural experiments indicate that there is variation within the R. pumilio (Jonkershoek and Goegap) taxon in odour quality, perception and preference. Expand
Comparative study of pollination biology of two closely related alpine Primula species, namely Primula beesiana and P. bulleyana (Primulaceae)
TLDR
The results indicate that both P. beesiana and P. bulleyana are two distinct species, and the reproductive isolation of the two species is probably an important mechanism in maintaining species boundaries in the genus and has contributed to the species diversification of Primula in the area. Expand
Reproductive isolation and pollination success of rewarding Galearis diantha and non-rewarding Ponerorchis chusua (Orchidaceae).
TLDR
The results do not support either the facilitation or competition hypothesis regarding the effect of nearby rewarding flowers on non-rewarding plants, and a combination of mechanical isolation and incomplete ethological isolation eliminates the possibility of pollen transfer between the species.

Quantitative trait loci affecting differences in floral morphology between two species of monkeyflower (Mimulus).
TLDR
The genetic control of 12 morphological differences between the flowers of M. lewisii and M. cardinalis implies that either single genes of individually large effect or linked clusters of genes with a large cumulative effect can play a role in the evolution of reproductive isolation and speciation. Expand
Pollination, angiosperm speciation, and the nature of species boundaries

The time is ripe to initiate several lines of further research on pollination to understand whether different suites of pollinators can affect consistent selection in different directions on floral characteristics, and how reproductive isolation arises within and among populations, races, and higher taxa of plants.

TLDR
Results suggest that genes of large effect on pollinator preference have contributed to floral evolution and premating reproductive isolation in these monkeyflowers, contributing to growing evidence that adaptation and reproductive isolation may often involve major genes. Expand

TLDR
Mechanical and ethological isolation between species is widespread in angiosperms with specialized animal-pollinated flowers, being recorded in 29 species groups belonging to 27 genera and 16 families, and three modes of origin of floral isolation are confirmed by evidence. Expand

TLDR
The combination of these three incomplete external isolating mechanisms is sufficient to maintain the distinctness of the ornithophilous and sphingophILous species in some areas of sympatric coexistence. Expand
