Hybridization between species can lead to introgression of genes from one species to another, providing a potential mechanism for preserving and recombining key traits during evolution. To determine the molecular basis of such transfers, we analyzed a natural polymorphism for flower-head development in Senecio. We show that the polymorphism arose by introgression of a cluster of regulatory genes, the RAY locus, from the diploid species S. squalidus into the tetraploid S. vulgaris. The RAY genes… Expand
Introgression of fitness genes across a ploidy barrier.
TLDR
This work focuses on introgression between the diploid species, Senecio squalidus, and the tetraploid, S. vulgaris, which resulted in the origin of a variant form of S. Vulgaris that produces radiate rather than nonradiate flower heads and identifies a copy of RAY2 homeologous to the copy (RAY2a) previously isolated, thus providing further evidence that S vulgaris is allotetraploids.

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.

Evolution of novel mimicry rings facilitated by adaptive introgression in tropical butterflies
TLDR
The findings support the role of regulatory modularity coupled with adaptive introgression as an elegant mechanism by which novel phenotypic combinations can evolve and fuel an adaptive radiation. Expand
Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
TLDR
It is inferred that closely related Heliconius species exchange protective colour-pattern genes promiscuously, implying that hybridization has an important role in adaptive radiation. Expand
THE POPULATION GENETICS OF SPOROPHYTIC SELF‐INCOMPATIBILITY IN THREE HYBRIDIZING SENECIO (ASTERACEAE) SPECIES WITH CONTRASTING POPULATION HISTORIES
TLDR
This study investigates the SI mating systems of three hybridizing Senecio species with contrasting population histories and shows that all three species express sporophytic SI (SSI), where pollen incompatibility is controlled by the diploid parental genome, and that SSI is inherited and functions normally in hybrids. Expand
Genomics of Evolutionary Novelty in Hybrids and Polyploids
TLDR
This work focuses on the types of molecular genetic and genomic processes that might be set in motion by the saltational event of genome merger between two diverged species, either with or without genome doubling, and how these various processes can contribute to novel phenotypes. Expand
Lessons from Natural and Artificial Polyploids in Higher Plants
TLDR
An overview of lessons learnt from studies of natural and artificial polyploids, and from comparisons between the 2, covering basic cellular and metabolic consequences through to alterations in epigenetic gene regulation, together with 2 in-depth case studies in Senecio and Glycine are presented. Expand
Floral symmetry genes and the origin and maintenance of zygomorphy in a plant-pollinator mutualism
TLDR
Three evolutionary models that may have given rise to this patterning are considered, including the hypothesis that floral zygomorphy in Malpighiaceae arose earlier than standard morphology-based character reconstructions suggest. Expand
Genome Size Variation in a Hybridizing Diploid Species Complex in Anacyclus (Asteraceae: Anthemideae)
TLDR
The patterns of genome size variation observed in sympatric populations of A. clavatus and A. valentinus support the occurrence of current gene flow between these species and the existence of contact areas in overlapping distribution areas where phenotypic and genomic variation increases. Expand
Senecio as a model system for integrating studies of genotype, phenotype and fitness.
TLDR
The genus Senecio (Asteraceae) is presented as an excellent system to integrate developments of quantitative genetics with ecological experiments, and to address fundamental questions in ecology and evolution. Expand

Evolution of genetic mechanisms controlling petal development
TLDR
Although expression of these orthologues in the stamens is conserved, the expression patterns in the petals differ from those found in the higher eudicots, suggesting that the function of AP3 and PI homologues as B -class organ-identity genes is not rigidly conserved among all angiosperms. Expand
The evolution of apical dominance in maize
TLDR
The cloned teosinte branched1 (tb1) gene encodes a protein with homology to the cycloidea gene of snapdragon and suggests that tb1 acts both to repress the growth of axillary organs and to enable the formation of female inflorescences. Expand
Routes of origin of two recently evolved hybrid taxa: Senecio vulgaris var. hibernicus and York radiate groundsel (Asteraceae).
TLDR
It was evident that hybrid offspring similar in morphology to the two introgressant taxa were more often produced in backcrosses to S. vulgaris than in segregating F2 or F3 generations, and that fertile hybrid progeny were formed within two generations. Expand
