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.'
