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. '
