| inferring population history from fine-scale spatial genetic analysis in oryza rufipogon (poaceae). | determining the genetic structure of an in situ conserved population can provide insight into the dynamics of population genetic processes associated with successful plant conservation. we used 21 microsatellite loci to analyse the genetic relationships among individuals (n = 813) collected from a small oryza rufipogon population conserved since 1993 in hunan province of china. the analysis revealed four distinct genetic subpopulations (f(st) = 0.145) without geographic isolation. one subpopulat ... | 2006 | 16629809 |
