The evolution of predominant self-fertilization from cross-fertilization in plants is accompanied by diverse changes to morphology, ecology and genetics, some of which likely result from regulatory changes in gene expression. We examined changes in gene expression during early stages in the transition to selfing in populations of animal-pollinated Eichhornia paniculata with contrasting mating patterns. We crossed plants from outcrossing and selfing populations and tested for the presence of…

No Excess of Cis-Regulatory Variation Associated with Intraspecific Selection in Wild Pearl Millet (Cenchrus americanus)
TLDR
The results favor the hypothesis that enrichment of adaptive cis-regulatory divergence builds up over time, for short evolutionary time-scales, cis-acting mutations are not predominantly involved in adaptive evolution associated with strong selective signal.
Tansley review ‘Amost complexmarriagearrangement’: recent advances on heterostyly and unresolved questions
TLDR
Ecological, phylogenetic andmolecular genetic data have validated some features of theoretical models on the selection of the polymorphism, and many unanswered questions remain.
Bayesian Inference of Allele-Specific Gene Expression Indicates Abundant Cis-Regulatory Variation in Natural Flycatcher Populations
TLDR
The results suggest that genetic variation in regulatory sequences commonly affects gene expression in natural populations and that it provides a seedbed for phenotypic evolution via divergence in gene expression.
'A most complex marriage arrangement': recent advances on heterostyly and unresolved questions.
TLDR
Ecological, phylogenetic and molecular genetic data have validated some features of theoretical models on the selection of the polymorphism, and heterostyly is the best-understood floral polymorphism in angiosperms, many unanswered questions remain.

Cis-Regulatory Changes Associated with a Recent Mating System Shift and Floral Adaptation in Capsella
TLDR
The results suggest that cis-regulatory changes have been important during the recent adaptive floral evolution in Capsella and that differences in TE dynamics between selfing and outcrossing species could be important for rapid regulatory divergence in association with mating system shifts.
GENETIC ARCHITECTURE AND ADAPTIVE SIGNIFICANCE OF THE SELFING SYNDROME IN CAPSELLA
TLDR
The genetic architecture and evolutionary forces underlying evolution of the selfing syndrome in Capsella rubella following its recent divergence from the outcrossing ancestor C. grandiflora are characterized and the directionality of QTL effects, as well as population genetic patterns of polymorphism and divergence at 318 loci, are consistent with a history of directional selection on theSelfing syndrome.
The demography and population genomics of evolutionary transitions to self-fertilization in plants
TLDR
The simulation results cast doubt on whether it is possible to infer the role of bottlenecks associated with reproductive assurance in the evolution of selfing, and indicate that the effects of background selection on the loss of diversity and efficacy of selection occur rapidly following the shift to high selfing.
Evolutionary pathways to self-fertilization in a tristylous plant species.
TLDR
The origins and pathways by which selfing has evolved in tristylous Eichhornia paniculata are investigated by providing new evidence based on morphology, DNA sequences and genetic analysis.
Inheritance of mating-system modifier genes in Eichhornia paniculata (Pontederiaceae)
TLDR
The results provide evidence that the evolution of self-fertilization in E. paniculata has occurred by different genetic pathways and suggest that the sequence of events commences with the fixation of recessive alleles affecting only filament length, followed by evolution at modifier loci responsible for larger phenotypic changes to floral architecture.
Genomic consequences of transitions from cross- to self-fertilization on the efficacy of selection in three independently derived selfing plants
TLDR
These findings are consistent with a small reduction in the efficacy of selection on protein sequences associated with transitions to selfing, and reduced selection in selfers on synonymous changes that influence codon usage.
The genetic architecture of traits associated with the evolution of self-pollination in Mimulus.
TLDR
A moderately polygenic and highly directional basis for floral size evolution is found, suggesting adaptation from standing variation or in pursuit of a moving optimum, whereas only a few major loci accounted for substantial flowering-time divergence.
Mating system shifts and transposable element evolution in the plant genus Capsella
TLDR
The results suggest that the evolution of selfing may have different effects on TE evolution on a short and on a long timescale, and cross-species comparisons of transposon abundance are sensitive to reference genome bias, and efforts to control for this bias are key when making comparisons across species.

TLDR
The overall objective is to show that PIO's reflect the likelihood of sufficient pollen grains reaching each stigma to result in maximum seed set and suggest that PI O's are integrated with other facets of a plant's breeding system.
Genome-wide analysis of cis-regulatory divergence between species in the Arabidopsis genus.
TLDR
The asymmetry in the direction of allele-specific expression suggests interspecific differences in the efficiency of gene silencing in F1 hybrids, and the epigenetic landscape of histone methylation in A. thaliana genome associate with ASE.
