Repeated Evolutionary Changes of Leaf Morphology Caused by Mutations to a Homeobox Gene
TLDR
It is demonstrated that the REDUCED COMPLEXITY (RCO) locus underlies more than one naturally evolved change in leaf shape in the Brassicaceae, and it is found that temperature-responsive expression of RCO-A can explain the phenotypic plasticity of leaf shape to ambient temperature in Capsella, suggesting a molecular basis for the well-known negative correlation between temperature and leaf margin dissection. Expand
Divergent sorting of a balanced ancestral polymorphism underlies the establishment of gene-flow barriers in Capsella
TLDR
It is shown that NPR1 and RPP5 loci cause a genetic incompatibility between the incipient species Capsella grandiflora and C. rubella, and the more distantly related C. orientalis. Expand
Association mapping reveals the role of purifying selection in the maintenance of genomic variation in gene expression
TLDR
Overall, the results show that the distribution of frequencies and effect sizes of the loci responsible for local expression variation within a single outcrossing population are consistent with the effects of purifying selection. Expand
Mutational disruption of the ABCC2 gene in fall armyworm, Spodoptera frugiperda, confers resistance to the Cry1Fa and Cry1A.105 insecticidal proteins
TLDR
It is confirmed that ABCC2 is a receptor for Cry1Fa and Cry1A.105 in S. frugiperda, and the groundwork for genetically enabled resistance management in this species is laid, with the caution that there may be several distinct ABCC 2 resistances alleles in nature. 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
Standing genetic variation in a tissue-specific enhancer underlies selfing-syndrome evolution in Capsella
TLDR
It is demonstrated that allelic variation in the intron of a general growth regulator contributed to the specific reduction of petal size after the transition to selfing in the genus Capsella, demonstrating how tissue-specific regulatory elements in pleiotropic genes contribute to organ-specific evolution. Expand
Identifying the genes underlying quantitative traits: a rationale for the QTN programme
TLDR
The ways by which the QTN programme can offer unique insight into the ecology and evolution of adaptation in plants are discussed. Expand
The evolutionary forces shaping cis and trans regulation of gene expression within a population of outcrossing plants
TLDR
This work identifies loci that affect gene expression in trans using genomic and transcriptomic data from one population of the obligately outcrossing plant, Capsella grandiflora, and highlights the different selective pressures shaping variation in cis- and trans- gene regulation. Expand
A Segregating Inversion Generates Fitness Variation in Yellow Monkeyflower (Mimulus guttatus)
TLDR
The data suggest that opposing fitness effects maintain an intermediate frequency, and as a consequence, inv6 generates inbreeding depression and high genetic variance, suggesting counterbalancing fitness benefits that maintain the polymorphism. Expand
