Microgeographic adaptation provides a particularly interesting context for understanding the genetic basis of phenotypic divergence and may also present unique empirical challenges. In particular, plant adaptation to extreme soil mosaics may generate barriers to gene flow or shifts in mating system that confound simple genomic scans for adaptive loci. Here, we combine three approaches – quantitative trait locus (QTL) mapping of candidate intervals in controlled crosses, population resequencing (PoolSeq) and analyses of wild recombinant individuals – to investigate one trait associated with
The genetic architecture of local adaptation has been of central interest to evolutionary biologists since the modern synthesis. In addition to classic theory on the effect size of adaptive mutations by Fisher, Kimura and Orr, recent theory addresses the genetic architecture of local adaptation in the face of ongoing gene flow. This theory predicts that with substantial gene flow between populations local adaptation should proceed primarily through mutations of large effect or tightly linked clusters of smaller effect loci. In this study, we investigate the genetic architecture of divergence in flowering time, mating system‐related traits, and leaf shape between

Abstract Mimulus guttatus (yellow monkeyflower) adaptation to geothermal soils in Yellowstone National Park. We mapped a majorQTL causing dense leaf trichomes in thermally adapted plants to a <50‐kb region of linkage Group 14 (Tr14) previously implicated in trichome divergence between independentM. guttatus populations. A PoolSeq scan of Tr14 region revealed a cluster of six genes, coincident with the inferredQTL peak, with high allele frequency differences sufficient to explain observed phenotypic differentiation. One of these, the R2R3MYB transcription factor Migut.N02661, is a plausible functional candidate and was also strongly associated (r 2 = 0.27) with trichome phenotype in analyses of wild‐collected admixed individuals. Although functional analyses will be necessary to definitively link molecular variants in Tr14 with trichome divergence, our analyses are a major step in that direction. They point to a simple, and parallel, genetic basis for one axis ofMimulus guttatus adaptation to an extreme habitat, suggest a broadly conserved genetic basis for trichome variation across flowering plants and pave the way for further investigations of this challenging case of microgeographic incipient speciation. -

Abstract Discovering local adaptation, its genetic underpinnings, and environmental drivers is important for conserving forest species. Ecological genomic approaches coupled with next‐generation sequencing are useful means to detect local adaptation and uncover its underlying genetic basis in nonmodel species. We report results from a study on flowering dogwood trees (
Cornus florida L .) using genotyping by sequencing (GBS ). This species is ecologically important to easternUS forests but is severely threatened by fungal diseases. We analyzed subpopulations in divergent ecological habitats within North Carolina to uncover loci under local selection and associated with environmental–functional traits or disease infection. At this scale, we tested the effect of incorporating additional sequencing before scaling for a broader examination of the entire range. To test for biases ofGBS , we sequenced two similarly sampled libraries independently from six populations of three ecological habitats. We obtained environmental–functional traits for each subpopulation to identify associations with genotypes via latent factor mixed modeling (LFMM ) and gradient forests analysis. To test whether heterogeneity of abiotic pressures resulted in genetic differentiation indicative of local adaptation, we evaluatedF stper locus while accounting for genetic differentiation between coastal subpopulations and Piedmont‐Mountain subpopulations. Of the 54 candidate loci with sufficient evidence of being under selection among both libraries, 28–39 were Arlequin–BayeScanF stoutliers. ForLFMM , 45 candidates were associated with climate (of 54), 30 were associated with soil properties, and four were associated with plant health. Reanalysis of combined libraries showed that 42 candidate loci still showed evidence of being under selection. We conclude environment‐driven selection on specific loci has resulted in local adaptation in response to potassium deficiencies, temperature, precipitation, and (to a marginal extent) disease. High allele turnover along ecological gradients further supports the adaptive significance of loci speculated to be under selection. -

Abstract Floral attraction traits can significantly affect pollinator visitation patterns, but adaptive evolution of these traits may be constrained by correlations with other traits. In some cases, molecular pathways contributing to floral attraction are well characterized, offering the opportunity to explore loci potentially underlying variation among individuals. Here, we quantify the range of variation in floral
UV patterning (i.e.UV ‘bulls‐eye nectar guides) among crop and wild accessions ofBrassica rapa . We then use experimental crosses to examine the genetic architecture, candidate loci and biochemical underpinnings of this patterning as well as phenotypic manipulations to test the ecological impact. We find qualitative variation inUV patterning between wild (commonly lackingUV patterns) and crop (commonly exhibitingUV patterns) accessions. Similar to the majority of crops, recombinant inbred lines (RIL s) derived from an oilseed crop ×WI fast‐plant®cross exhibitUV patterns, the size of which varies extensively among genotypes. InRIL s, we further observe strong statistical‐genetic andQTL correlations within petal morphological traits and within measurements of petalUV patterning; however, correlations between morphology andUV patterning are weak or nonsignificant, suggesting thatUV patterning is regulated and may evolve independently of overall petal size.HPLC analyses reveal a high concentration of sinapoyl glucose inUV ‐absorbing petal regions, which, in concert with physical locations ofUV ‐traitQTL s, suggest a regulatory and structural gene as candidates underlying observed quantitative variation. Finally, insects prefer flowers withUV bulls‐eye patterns over those that lack patterns, validating the importance ofUV patterning in pollen‐limited populations ofB. rapa . -

Abstract The integrated responses of biological systems to genetic and environmental variation result in substantial covariance in multiple phenotypes. The resultant pleiotropy, environmental effects, and genotype‐by‐environmental interactions (GxE) are foundational to our understanding of biology and genetics. Yet, the treatment of correlated characters, and the identification of the genes encoding functions that generate this covariance, has lagged. As a test case for analyzing the genetic basis underlying multiple correlated traits, we analyzed maize kernel ionomes from Intermated B73 x Mo17 (
IBM ) recombinant inbred populations grown in 10 environments. Plants obtain elements from the soil through genetic and biochemical pathways responsive to physiological state and environment. Most perturbations affect multiple elements which leads theionome , the full complement of mineral nutrients in an organism, to vary as an integrated network rather than a set of distinct single elements. We compared quantitative trait loci (QTL ) determining single‐element variation toQTL that predict variation in principal components (PC s) of multiple‐element covariance. Single‐element and multivariate approaches detected partially overlapping sets of loci.QTL influencing trait covariation were detected at loci that were not found by mapping single‐element traits. Moreover, this approach permitted testing environmental components of trait covariance, and identified multi‐element traits that were determined by both genetic and environmental factors as well as genotype‐by‐environment interactions. Growth environment had a profound effect on the elemental profiles and multi‐element phenotypes were significantly correlated with specific environmental variables. -

Abstract Flowering time and water‐use efficiency (
WUE ) are two ecological traits that are important for plant drought response. To understand the evolutionary significance of natural genetic variation in flowering time,WUE , andWUE plasticity to drought inArabidopsis thaliana , we addressed the following questions: (1) How are ecophysiological traits genetically correlated within and between different soil moisture environments? (2) Does terminal drought select for early flowering and drought escape? (3) IsWUE plasticity to drought adaptive and/or costly? We measured a suite of ecophysiological and reproductive traits on 234 spring flowering accessions ofA. thaliana grown in well‐watered and season‐ending soil drying treatments, and quantified patterns of genetic variation, correlation, and selection within each treatment.WUE and flowering time were consistently positively genetically correlated.WUE was correlated withWUE plasticity, but the direction changed between treatments. Selection generally favored early flowering and lowWUE , with drought favoring earlier flowering significantly more than well‐watered conditions. Selection for lowerWUE was marginally stronger under drought. There were no net fitness costs ofWUE plasticity.WUE plasticity (per se) was globally neutral, but locally favored under drought. Strong genetic correlation betweenWUE and flowering time may facilitate the evolution of drought escape, or constrain independent evolution of these traits. Terminal drought favored drought escape in these spring flowering accessions ofA. thaliana .WUE plasticity may be favored over completely fixed development in environments with periodic drought.
