Breeding Systems in the Legumes.

Nearly half of all land plant species are self-incompatible. While the molecular mechanisms that underpin self-incompatibility differ across angiosperms, they share some important features, including a fundamental role in shaping the genetic structure of populations and frequent transitions to self-compatibility. Independent gains and the persistence of many such mechanisms across vast timescales suggests a strong role of natural selection. And yet, surprisingly little is known regarding the distribution of incompatibility systems and their genetic and molecular bases in some of the largest angiosperm families, including the legumes (Fabaceae). Mary T. Kalin-Arroyo (1981) analyzed a breeding system collection of nearly 400 species in this family. Here, we re-visit the same sources of data, as well as add new data, which yields a total of 1200 species--roughly 6% of the family--across all subfamilies and 189 genera. We use this data to examine the implications of the phylogenetic distribution of breeding systems in the family.
