text: Many studies have quantified the distribution of heterozygosity and relatedness
in natural populations, but few have examined the demographic processes driving
these patterns. In this study, we take a novel approach by studying how population
structure affects both pairwise identity and the distribution of heterozygosity
in a natural population of the self-incompatible plant Antirrhinum majus. Excess
variance in heterozygosity between individuals is due to identity disequilibrium,
which reflects the variance in inbreeding between individuals; it is measured
by the statistic g2. We calculated g2 together with FST and pairwise relatedness
(Fij) using 91 SNPs in 22,353 individuals collected over 11 years. We find that
pairwise Fij declines rapidly over short spatial scales, and the excess variance
in heterozygosity between individuals reflects significant variation in inbreeding.
Additionally, we detect an excess of individuals with around half the average
heterozygosity, indicating either selfing or matings between close relatives.
We use 2 types of simulation to ask whether variation in heterozygosity is consistent
with fine-scale spatial population structure. First, by simulating offspring using
parents drawn from a range of spatial scales, we show that the known pollen dispersal
kernel explains g2. Second, we simulate a 1,000-generation pedigree using the
known dispersal and spatial distribution and find that the resulting g2 is consistent
with that observed from the field data. In contrast, a simulated population with
uniform density underestimates g2, indicating that heterogeneous density promotes
identity disequilibrium. Our study shows that heterogeneous density and leptokurtic
dispersal can together explain the distribution of heterozygosity.

text: Many recent studies have addressed the mechanisms operating during the early
stages of speciation, but surprisingly few studies have tested theoretical predictions
on the evolution of strong reproductive isolation (RI). To help address this gap,
we first undertook a quantitative review of the hybrid zone literature for flowering
plants in relation to reproductive barriers. Then, using Populus as an exemplary
model group, we analysed genome-wide variation for phylogenetic tree topologies
in both early- and late-stage speciation taxa to determine how these patterns
may be related to the genomic architecture of RI. Our plant literature survey
revealed variation in barrier complexity and an association between barrier number
and introgressive gene flow. Focusing on Populus, our genome-wide analysis of
tree topologies in speciating poplar taxa points to unusually complex genomic
architectures of RI, consistent with earlier genome-wide association studies.
These architectures appear to facilitate the ‘escape’ of introgressed genome segments
from polygenic barriers even with strong RI, thus affecting their relationships
with recombination rates. Placed within the context of the broader literature,
our data illustrate how phylogenomic approaches hold great promise for addressing
the evolution and temporary breakdown of RI during late stages of speciation.

text: Pollinators display a remarkable diversity of foraging strategies with flowering
plants, from primarily mutualistic interactions to cheating through nectar robbery.
Despite numerous studies on the effect of nectar robbing on components of plant
fitness, its contribution to reproductive isolation is unclear. We experimentally
tested the impact of different pollinator strategies in a natural hybrid zone
between two subspecies of Antirrhinum majus with alternate flower colour guides.
On either side of a steep cline in flower colour between Antirrhinum majus pseudomajus
(magenta) and A. m. striatum (yellow), we quantified the behaviour of all floral
visitors at different time points during the flowering season. Using long-run
camera surveys, we quantify the impact of nectar robbing on the number of flowers
visited per inflorescence and the flower probing time. We further experimentally
tested the effect of nectar robbing on female reproductive success by manipulating
the intensity of robbing. While robbing increased over time the number of legitimate
visitors tended to decrease concomitantly. We found that the number of flowers
pollinated on a focal inflorescence decreased with the number of prior robbing
events. However, in the manipulative experiment, fruit set and fruit volume did
not vary significantly between low robbing and control treatments. Our findings
challenge the idea that robbers have a negative impact on plant fitness through
female function. This study also adds to our understanding of the components of
pollinator-mediated reproductive isolation and the maintenance of Antirrhinum
hybrid zones.

text: "One of the most striking and consistent results in speciation genomics is
the heterogeneous divergence observed across the genomes of closely related species.
This pattern was initially attributed to different levels of gene exchange—with
divergence preserved at loci generating a barrier to gene flow but homogenized
at unlinked neutral loci. Although there is evidence to support this model, it
is now recognized that interpreting patterns of divergence across genomes is not
so straightforward. One \r\nproblem is that heterogenous divergence between populations
can also be generated by other processes (e.g. recurrent selective sweeps or background
selection) without any involvement of differential gene flow. Thus, integrated
studies that identify which loci are likely subject to divergent selection are
required to shed light on the interplay between selection and gene flow during
the early phases of speciation. In this issue of Molecular Ecology, Rifkin et
al. (2019) confront this challenge using a pair of sister morning glory species.
They wisely design their sampling to take the geographic context of individuals
into account, including geographically isolated (allopatric) and co‐occurring
(sympatric) populations. This enabled them to show that individuals are phenotypically
less differentiated in sympatry. They also found that the loci that resist introgression
are enriched for those most differentiated in allopatry and loci that exhibit
signals of divergent selection. One great strength of the \r\nstudy is the combination
of methods from population genetics and molecular evolution, including the development
of a model to simultaneously infer admixture proportions and selfing rates."

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.'

text: 'Self-incompatibility (SI) is a genetically based recognition system that
functions to prevent self-fertilization and mating among related plants. An enduring
puzzle in SI is how the high diversity observed in nature arises and is maintained.
Based on the underlying recognition mechanism, SI can be classified into two main
groups: self- and non-self recognition. Most work has focused on diversification
within self-recognition systems despite expected differences between the two groups
in the evolutionary pathways and outcomes of diversification. Here, we use a deterministic
population genetic model and stochastic simulations to investigate how novel S-haplotypes
evolve in a gametophytic non-self recognition (SRNase/S Locus F-box (SLF)) SI
system. For this model the pathways for diversification involve either the maintenance
or breakdown of SI and can vary in the order of mutations of the female (SRNase)
and male (SLF) components. We show analytically that diversification can occur
with high inbreeding depression and self-pollination, but this varies with evolutionary
pathway and level of completeness (which determines the number of potential mating
partners in the population), and in general is more likely for lower haplotype
number. The conditions for diversification are broader in stochastic simulations
of finite population size. However, the number of haplotypes observed under high
inbreeding and moderate to high self-pollination is less than that commonly observed
in nature. Diversification was observed through pathways that maintain SI as well
as through self-compatible intermediates. Yet the lifespan of diversified haplotypes
was sensitive to their level of completeness. By examining diversification in
a non-self recognition SI system, this model extends our understanding of the
evolution and maintenance of haplotype diversity observed in a self recognition
system common in flowering plants.'

text: 'Genomes of closely-related species or populations often display localized
regions of enhanced relative sequence divergence, termed genomic islands. It has
been proposed that these islands arise through selective sweeps and/or barriers
to gene flow. Here, we genetically dissect a genomic island that controls flower
color pattern differences between two subspecies of Antirrhinum majus, A.m.striatum
and A.m.pseudomajus, and relate it to clinal variation across a natural hybrid
zone. We show that selective sweeps likely raised relative divergence at two tightly-linked
MYB-like transcription factors, leading to distinct flower patterns in the two
subspecies. The two patterns provide alternate floral guides and create a strong
barrier to gene flow where populations come into contact. This barrier affects
the selected flower color genes and tightlylinked loci, but does not extend outside
of this domain, allowing gene flow to lower relative divergence for the rest of
the chromosome. Thus, both selective sweeps and barriers to gene flow play a role
in shaping genomic islands: sweeps cause elevation in relative divergence, while
heterogeneous gene flow flattens the surrounding "sea," making the island of divergence
stand out. By showing how selective sweeps establish alternative adaptive phenotypes
that lead to barriers to gene flow, our study sheds light on possible mechanisms
leading to reproductive isolation and speciation.'

text: 'Pedigree and sibship reconstruction are important methods in quantifying
relationships and fitness of individuals in natural populations. Current methods
employ a Markov chain-based algorithm to explore plausible possible pedigrees
iteratively. This provides accurate results, but is time-consuming. Here, we develop
a method to infer sibship and paternity relationships from half-sibling arrays
of known maternity using hierarchical clustering. Given 50 or more unlinked SNP
markers and empirically derived error rates, the method performs as well as the
widely used package Colony, but is faster by two orders of magnitude. Using simulations,
we show that the method performs well across contrasting mating scenarios, even
when samples are large. We then apply the method to open-pollinated arrays of
the snapdragon Antirrhinum majus and find evidence for a high degree of multiple
mating. Although we focus on diploid SNP data, the method does not depend on marker
type and as such has broad applications in nonmodel systems. '

text: Small RNAs (sRNAs) regulate genes in plants and animals. Here, we show that
population-wide differences in color patterns in snapdragon flowers are caused
by an inverted duplication that generates sRNAs. The complexity and size of the
transcripts indicate that the duplication represents an intermediate on the pathway
to microRNA evolution. The sRNAs repress a pigment biosynthesis gene, creating
a yellow highlight at the site of pollinator entry. The inverted duplication exhibits
steep clines in allele frequency in a natural hybrid zone, showing that the allele
is under selection. Thus, regulatory interactions of evolutionarily recent sRNAs
can be acted upon by selection and contribute to the evolution of phenotypic diversity.

text: Sexual dimorphism in resource allocation is expected to change during the
life cycle of dioecious plants because of temporal differences between the sexes
in reproductive investment. Given the potential for sex-specific differences in
reproductive costs, resource availability may contribute to variation in reproductive
allocation in females and males. Here, we used Rumex hastatulus, a dioecious,
wind-pollinated annual plant, to investigate whether sexual dimorphism varies
with life-history stage and nutrient availability, and determine whether allocation
patterns differ depending on reproductive commitment. To examine if the costs
of reproduction varied between the sexes, reproduction was either allowed or prevented
through bud removal, and biomass allocation was measured at maturity. In a second
experiment to assess variation in sexual dimorphism across the life cycle, and
whether this varied with resource availability, plants were grown in high and
low nutrients and allocation to roots, aboveground vegetative growth and reproduction
were measured at three developmental stages. Males prevented from reproducing
compensated with increased above- and belowground allocation to a much larger
degree than females, suggesting that male reproductive costs reduce vegetative
growth. The proportional allocation to roots, reproductive structures and aboveground
vegetative growth varied between the sexes and among life-cycle stages, but not
with nutrient treatment. Females allocated proportionally more resources to roots
than males at peak flowering, but this pattern was reversed at reproductive maturity
under low-nutrient conditions. Our study illustrates the importance of temporal
dynamics in sex-specific resource allocation and provides support for high male
reproductive costs in wind-pollinated plants.

text: Background and aims Angiosperms display remarkable diversity in flower colour,
implying that transitions between pigmentation phenotypes must have been common.
Despite progress in understanding transitions between anthocyanin (blue, purple,
pink or red) and unpigmented (white) flowers, little is known about the evolutionary
patterns of flower-colour transitions in lineages with both yellow and anthocyanin-pigmented
flowers. This study investigates the relative rates of evolutionary transitions
between different combinations of yellow- and anthocyanin-pigmentation phenotypes
in the tribe Antirrhineae. Methods We surveyed taxonomic literature for data on
anthocyanin and yellow floral pigmentation for 369 species across the tribe. We
then reconstructed the phylogeny of 169 taxa and used phylogenetic comparative
methods to estimate transition rates among pigmentation phenotypes across the
phylogeny. Key Results In contrast to previous studies we found a bias towards
transitions involving a gain in pigmentation, although transitions to phenotypes
with both anthocyanin and yellow taxa are nevertheless extremely rare. Despite
the dominance of yellow and anthocyanin-pigmented taxa, transitions between these
phenotypes are constrained to move through a white intermediate stage, whereas
transitions to double-pigmentation are very rare. The most abundant transitions
are between anthocyanin-pigmented and unpigmented flowers, and similarly the most
abundant polymorphic taxa were those with anthocyanin-pigmented and unpigmented
flowers. Conclusions Our findings show that pigment evolution is limited by the
presence of other floral pigments. This interaction between anthocyanin and yellow
pigments constrains the breadth of potential floral diversity observed in nature.
In particular, they suggest that selection has repeatedly acted to promote the
spread of single-pigmented phenotypes across the Antirrhineae phylogeny. Furthermore,
the correlation between transition rates and polymorphism suggests that the forces
causing and maintaining variance in the short term reflect evolutionary processes
on longer time scales.

text: Understanding the relative importance of heterosis and outbreeding depression
over multiple generations is a key question in evolutionary biology and is essential
for identifying appropriate genetic sources for population and ecosystem restoration.
Here we use 2455 experimental crosses between 12 population pairs of the rare
perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigate the multi-generational
(F1, F2, F3) fitness outcomes of inter-population hybridization. We detected no
evidence of outbreeding depression, with inter-population hybrids and backcrosses
showing either similar fitness or significant heterosis for fitness components
across the three generations. Variation in heterosis among population pairs was
best explained by characteristics of the foreign source or home population, and
was greatest when the source population was large, with high genetic diversity
and low inbreeding, and the home population was small and inbred. Our results
indicate that the primary consideration for maximizing progeny fitness following
population augmentation or restoration is the use of seed from large, genetically
diverse populations.

text: 'Since Darwin''s pioneering research on plant reproductive biology (e.g. Darwin
1877), understanding the mechanisms maintaining the diverse sexual strategies
of plants has remained an important challenge for evolutionary biologists. In
some species, populations are sexually polymorphic and contain two or more mating
morphs (sex phenotypes). Differences in morphology or phenology among the morphs
influence patterns of non-random mating. In these populations, negative frequency-dependent
selection arising from disassortative (intermorph) mating is usually required
for the evolutionary maintenance of sexual polymorphism, but few studies have
demonstrated the required patterns of non-random mating. In the current issue
of Molecular Ecology, Shang (2012) make an important contribution to our understanding
of how disassortative mating influences sex phenotype ratios in Acer pictum subsp.
mono (painted maple), a heterodichogamous, deciduous tree of eastern China. They
monitored sex expression in 97 adults and used paternity analysis of open-pollinated
seed to examine disassortative mating among three sex phenotypes. Using a deterministic
''pollen transfer'' model, Shang et al. present convincing evidence that differences
in the degree of disassortative mating in progeny arrays of the sex phenotypes
can explain their uneven frequencies in the adult population. This study provides
a useful example of how the deployment of genetic markers, demographic monitoring
and modelling can be integrated to investigate the maintenance of sexual diversity
in plants. '

text: Understanding patterns and correlates of local adaptation in heterogeneous
landscapes can provide important information in the selection of appropriate seed
sources for restoration. We assessed the extent of local adaptation of fitness
components in 12 population pairs of the perennial herb Rutidosis leptorrhynchoides
(Asteraceae) and examined whether spatial scale (0.7-600 km), environmental distance,
quantitative (QST) and neutral (FST) genetic differentiation, and size of the
local and foreign populations could predict patterns of adaptive differentiation.
Local adaptation varied among populations and fitness components. Including all
population pairs, local adaptation was observed for seedling survival, but not
for biomass, while foreign genotype advantage was observed for reproduction (number
of inflorescences). Among population pairs, local adaptation increased with QST
and local population size for biomass. QST was associated with environmental distance,
suggesting ecological selection for phenotypic divergence. However, low FST and
variation in population structure in small populations demonstrates the interaction
of gene flow and drift in constraining local adaptation in R. leptorrhynchoides.
Our study indicates that for species in heterogeneous landscapes, collecting seed
from large populations from similar environments to candidate sites is likely
to provide the most appropriate seed sources for restoration.
