text: Domestication is a human‐induced selection process that imprints the genomes
of domesticated populations over a short evolutionary time scale and that occurs
in a given demographic context. Reconstructing historical gene flow, effective
population size changes and their timing is therefore of fundamental interest
to understand how plant demography and human selection jointly shape genomic divergence
during domestication. Yet, the comparison under a single statistical framework
of independent domestication histories across different crop species has been
little evaluated so far. Thus, it is unclear whether domestication leads to convergent
demographic changes that similarly affect crop genomes. To address this question,
we used existing and new transcriptome data on three crop species of Solanaceae
(eggplant, pepper and tomato), together with their close wild relatives. We fitted
twelve demographic models of increasing complexity on the unfolded joint allele
frequency spectrum for each wild/crop pair, and we found evidence for both shared
and species‐specific demographic processes between species. A convergent history
of domestication with gene flow was inferred for all three species, along with
evidence of strong reduction in the effective population size during the cultivation
stage of tomato and pepper. The absence of any reduction in size of the crop in
eggplant stands out from the classical view of the domestication process; as does
the existence of a “protracted period” of management before cultivation. Our results
also suggest divergent management strategies of modern cultivars among species
as their current demography substantially differs. Finally, the timing of domestication
is species‐specific and supported by the few historical records available.

text: Interspecific crossing experiments have shown that sex chromosomes play a
major role in reproductive isolation between many pairs of species. However, their
ability to act as reproductive barriers, which hamper interspecific genetic exchange,
has rarely been evaluated quantitatively compared to Autosomes. This genome-wide
limitation of gene flow is essential for understanding the complete separation
of species, and thus speciation. Here, we develop a mainland-island model of secondary
contact between hybridizing species of an XY (or ZW) sexual system. We obtain
theoretical predictions for the frequency of introgressed alleles, and the strength
of the barrier to neutral gene flow for the two types of chromosomes carrying
multiple interspecific barrier loci. Theoretical predictions are obtained for
scenarios where introgressed alleles are rare. We show that the same analytical
expressions apply for sex chromosomes and autosomes, but with different sex-averaged
effective parameters. The specific features of sex chromosomes (hemizygosity and
absence of recombination in the heterogametic sex) lead to reduced levels of introgression
on the X (or Z) compared to autosomes. This effect can be enhanced by certain
types of sex-biased forces, but it remains overall small (except when alleles
causing incompatibilities are recessive). We discuss these predictions in the
light of empirical data comprising model-based tests of introgression and cline
surveys in various biological systems.

text: 'Plant mating systems play a key role in structuring genetic variation both
within and between species. In hybrid zones, the outcomes and dynamics of hybridization
are usually interpreted as the balance between gene flow and selection against
hybrids. Yet, mating systems can introduce selective forces that alter these expectations;
with diverse outcomes for the level and direction of gene flow depending on variation
in outcrossing and whether the mating systems of the species pair are the same
or divergent. We present a survey of hybridization in 133 species pairs from 41
plant families and examine how patterns of hybridization vary with mating system.
We examine if hybrid zone mode, level of gene flow, asymmetries in gene flow and
the frequency of reproductive isolating barriers vary in relation to mating system/s
of the species pair. We combine these results with a simulation model and examples
from the literature to address two general themes: (i) the two‐way interaction
between introgression and the evolution of reproductive systems, and (ii) how
mating system can facilitate or restrict interspecific gene flow. We conclude
that examining mating system with hybridization provides unique opportunities
to understand divergence and the processes underlying reproductive isolation.'
