| genetic structure and putative selective sweep in the pioneer tree, zanthoxylum ailanthoides. | zanthoxylum ailanthoides siebold & zucc. is one of the most frequently encountered pioneer trees in japanese warm-temperate evergreen oak forests. our previous study in one region of japan suggested high levels of population differentiation and putative natural selection acting on one of the nuclear loci analyzed. here, we extend our analysis to study the genetic structure of 10 populations of z. ailanthoides across japan using 9 simple sequence repeat (ssr) loci for a better understanding of it ... | 2010 | 20035437 |
