Abstract: | Background Understanding the mechanisms that control species genetic structure has always been a major objective in evolutionary studies.
The association between genetic structure and species attributes has received special attention. As species attributes are
highly taxonomically constrained, phylogenetically controlled methods are necessary to infer causal relationships. In plants,
a previous study controlling for phylogenetic signal has demonstrated that Wright's F
ST, a measure of genetic differentiation among populations, is best predicted by the mating system (outcrossing, mixed-mating
or selfing) and that plant traits such as perenniality and growth form have only an indirect influence on F
ST via their association with the mating system. The objective of this study is to further outline the determinants of plant
genetic structure by distinguishing the effects of mating system on gene flow and on genetic drift. The association of biparental
inbreeding and inbreeding depression with population genetic structure, mating system and plant traits are also investigated. |
