The Genomic Signal of Partial Sweeps in Mimulus guttatus
TLDR
The genomic signal of soft sweeps within an artificial selection experiment on Mimulus guttatus is investigated and significant increases in nucleotide variation around selected loci in the population evolving larger flowers suggest that “high” alleles for flower size were initially less frequent than “low’ alleles. Expand
Comparative linkage maps suggest that fission, not polyploidy, underlies near-doubling of chromosome number within monkeyflowers (Mimulus; Phrymaceae)
Changes in chromosome number and structure are important contributors to adaptation, speciation and macroevolution. In flowering plants, polyploidy and subsequent reductions in chromosome number byExpand
Distinguishing among modes of convergent adaptation using population genomic data
TLDR
A model-based, statistical approach that utilizes genomic data to detect cases of convergent adaptation at the genetic level, identify the loci involved and distinguish among these modes, and applies the method to data from four populations of the killifish that show very rapid convergence for tolerance to industrial pollutants. Expand
Interactions Among Flower-Size QTL of Mimulus guttatus Are Abundant but Highly Variable in Nature
TLDR
A comprehensive survey of interactions among a defined set of flower-size QTL: loci polymorphic within a single natural population of yellow monkeyflower (Mimulus guttatus) finds that epistasis is typical. Expand
Viability selection prior to trait expression is an essential component of natural selection
TLDR
It is found that fecundity is positively related to flower size, however, survival to flowering is much lower in large-flowers genotypes than in small-flowered genotypes, differs from the great majority of field studies, which suggest strong positive selection on flower size. Expand
Spatially and temporally varying selection on intrapopulation quantitative trait loci for a life history trade‐off in Mimulus guttatus
TLDR
This study reports a 3‐year field study of selection on intrapopulation quantitative trait loci of flower size, a highly polygenic trait in Mimulus guttatus, providing direct evidence of balancing selection mechanisms on QTL of an ecologically relevant trait. Expand

Distinguishing Among Modes of Convergent Adaptation Using Population Genomic Data
TLDR
This work identifies a single locus at which both independent mutation events and selection on an allele shared via gene flow, either slightly before or during selection, play a role in adaptation across the species’ range. Expand
The Genomic Architecture of Flowering Time Varies Across Space and Time in Mimulus guttatus
TLDR
This work develops a novel likelihood framework to identify segregating variation within multiple populations and generations while accommodating estimation error on a sample- and SNP-specific basis and uses this method to map loci for flowering time within natural populations of Mimulus guttatus. Expand
The genomic architecture of flowering time varies across space and time in Mimulus guttatus
TLDR
A novel likelihood framework is developed to identify segregating variation within multiple populations and generations while accommodating estimation error on a sample- and SNP-specific basis and to map loci for flowering time within natural populations of Mimulus guttatus. Expand

Unraveling Epistasis With Triple Testcross Progenies of Near-Isogenic Lines
TLDR
The findings suggested that additive main effects as well as additive-by-additive digenic epistasis strongly influence the genetic architecture underlying growth-related traits of A. thaliana. Expand
Adaptation from standing genetic variation.
TLDR
There is potential to distinguish between adaptation from standing variation and that from new mutations by differences in the genomic signature of selection. Expand
Data and Theory Point to Mainly Additive Genetic Variance for Complex Traits
TLDR
It is concluded that interactions at thelevel of genes are not likely to generate much interaction at the level of variance, and that additive variance typically accounts for over half, and often close to 100%, of the total genetic variance. Expand

TLDR
There is a renewed appreciation both for the importance of studying gene interactions and for addressing these questions in a unified, quantitative manner with the advent of high-throughput functional genomics. Expand
Genetic Design and Statistical Power of Nested Association Mapping in Maize
TLDR
The genetic and statistical properties of the nested association mapping (NAM) design currently being implemented in maize is investigated to dissect the genetic basis of complex quantitative traits. Expand
Mimulus is an emerging model system for the integration of ecological and genomic studies
TLDR
Some of the phenotypic and genetic diversity in the genus Mimulus are introduced and how direct genetic studies with Mimulus can address a wide spectrum of ecological and evolutionary questions are highlighted. Expand
Pollen limitation and natural selection on floral characters in the yellow monkeyflower, Mimulus guttatus.
TLDR
The novel pattern of selection on severely pollen-limited plants suggests that reproductive assurance against pollinator loss may have been directly involved in the floral evolution of closely related selfing taxa. Expand
Variation and constraint in plant evolution and development
The goal of this short review is to consider the interrelated phenomena of phenotypic variation and genetic constraint with respect to plant diversity. The unique aspects of plants, including sessileExpand
An Efficient Bayesian Model Selection Approach for Interacting Quantitative Trait Loci Models With Many Effects
TLDR
The Bayesian model selection framework for mapping epistatic QTL in experimental crosses is extended to include environmental effects and gene–environment interactions and a new, fast Markov chain Monte Carlo algorithm is proposed to explore the posterior distribution of unknowns. Expand

TLDR
It is argued that the compartmentalization of developmental processes can influence the diversification of serial repeats such as butterfly eyespots, even under strong selection. Expand
