Testing for local adaptation in Avena barbata: a classic example of ecotypic divergence.

Abstract excerpt

Forty years ago, Robert Allard and colleagues documented that the slender wild oat, Avena barbata, occurred in California as two multi-locus allozyme genotypes, associated with mesic and xeric habitats. This is arguably the first example of ecotypes identified by molecular techniques. Despite widespread citation, however, the inference of local adaptation of these ecotypes rested primarily on the allozyme...
