Negative epistasis in hybrid genomes commonly results in postzygotic isolation between divergent lineages. However, some genomic regions may be selectively neutral or adaptive in hybrids and thus may potentially cross species barriers. We examined postzygotic isolation between ecologically similar species of Louisiana Iris: Iris brevicaulis and I. fulva to determine the potential for adaptive introgression in nature. Line-cross analyses allowed us a general overview of the gene action… Expand
The Genetic Architecture of Reproductive Isolation in Louisiana Irises: Flowering Phenology
TLDR
The genetic architecture of divergent flowering phenologies that result in substantial reproductive isolation between the naturally hybridizing plant species Iris fulva and I. brevicaulis is reported on. Expand
QTL mapping reveals the genetic architecture of loci affecting pre- and post-zygotic isolating barriers in Louisiana Iris
TLDR
Co-dominant markers are used to identify regions where QTL are located both within and between backcross maps to compare the genetic architecture of reproductive isolation and fitness traits across treatments and years and predicted genomic regions where introgression may be more likely to occur.

LOCAL ADAPTATION, PHENOTYPIC DIFFERENTIATION, AND HYBRID FITNESS IN DIVERGED NATURAL POPULATIONS OF ARABIDOPSIS LYRATA
TLDR
Fitness components, hierarchical total fitness and differentiation in putatively ecologically important traits of plants from two diverged parental populations from different continents in the native climate conditions of the populations in Norway and in North Carolina are compared. Expand
Epistasis causes outbreeding depression in eucalypt hybrids
TLDR
It is argued that the development of favourable epistasis is a key mechanism underlying the genetic divergence of eucalypt species, and epistatic interactions is an important mechanism behind the evolution of post-zygotic reproductive barriers. Expand
Hybrid fitness, adaptation and evolutionary diversification: lessons learned from Louisiana Irises
TLDR
It is argued that a multitude of approaches, involving both experimental and natural environments, and incorporating both manipulative analyses and surveys of natural populations, are necessary to adequately test for the evolutionary significance of introgressive hybridization. Expand
Integrating Bayesian genomic cline analyses and association mapping of morphological and ecological traits to dissect reproductive isolation and introgression in a Louisiana Iris hybrid zone
TLDR
These findings provide insights into the complexity of the genomic architecture of phenotypic differences and are a first step towards identifying loci that are associated with both trait variation and reproductive isolation in nature. Expand
Differential response of the homoploid hybrid species Iris nelsonii (Iridaceae) and its progenitors to abiotic habitat conditions.
TLDR
The differential response to abiotic habitat conditions of I. nelsonii suggests that this species is ecologically divergent from its progenitor species. Expand
Incomplete reproductive isolation between Rhododendron taxa enables hybrid formation and persistence.
TLDR
Introgression, rather than speciation, is a probable evolutionary outcome of hybridization between the two Rhododendron taxa, and the absence of post-zygotic barriers between parental taxa indicates that the persistence of hybrids is likely. Expand
Hybrid breakdown caused by epistasis-based recessive incompatibility in a cross of rice (Oryza sativa L.).
Viability and fertility in organisms depend on epistatic interactions between loci maintained in lineages. Here, we describe reduced fitness of segregants (hybrid breakdown, HB) that emerged in an F2Expand
Allopatric origin of sympatric whitefish morphs with insights on the genetic basis of their reproductive isolation
TLDR
It is suggested that ecological adaptations in spawning time evolved in allopatry are currently maintaining partial reproductive isolation in the absence of other barriers to gene flow. Expand

GENETIC INTERACTIONS AND NATURAL SELECTION IN LOUISIANA IRIS HYBRIDS
TLDR
The traditional view that interactions between divergent genomes are always deleterious is an oversimplification and it seems likely that crosses between Divergent lineages can lead to the production of both fit and unfit hybrid genotypes. Expand

QTL ANALYSIS OF FLORAL TRAITS IN LOUISIANA IRIS HYBRIDS
TLDR
The QTL results imply that the genetic basis of floral morphology and color traits might facilitate the maintenance of phenotypic divergence between Iris fulva and Iris brevicaulis, although a great deal ofphenotypic variation was observed among hybrids. Expand
LOCI AFFECTING LONG‐TERM HYBRID SURVIVORSHIP IN LOUISIANA IRISES: IMPLICATIONS FOR REPRODUCTIVE ISOLATION AND INTROGRESSION
TLDR
It is found that hybrid survivorship is influenced by several genetic regions that regions of the genome that imcrease survivorship when in a heterozygous state should have an increased likelihood of passing across species boundaries, whereas those that decrease survivoship will be less likely to introgress.

TLDR
Examining the early- and late-generation fitness consequences of hybridization between two ecotypes of the selfing annual Avena barbata in a greenhouse environment as well as in two natural environments demonstrates how a single hybridization event can result in a number of outcomes including hybrid vigor, hybrid breakdown, and transgressive segregation.
