Evolution of ribosomal DNA (rDNA) genetic structure in colonial Californian populations of Avena barbata.

Genetics - 1 Feb 1995

Cluster P D, Allard R W

Abstract excerpt

DNA samples from 980 plants of Avena barbata from 48 ecologically diverse sites in California and Oregon were assayed to determine their genotype for two duplicated loci governing rDNA variants. More than 40 different rDNA genotypes were observed among which 5 made up 96% of our sample in environmentally homogeneous sites; predominant genotypes were less frequent and recombinant genotypes were more frequent in...
