| phylogeographical structure revealed by chloroplast dna variation in japanese beech (fagus crenata blume). | intraspecific genetic variation in three non-coding chloroplast dna (cpdna) regions (trnt-l and trnl-f spacers, and trnl intron) of japanese beech (fagus crenata blume) was investigated. this species is a major constituent of the typical cool-temperate deciduous forests in japan. twenty-one f. crenata populations from throughout japan, and four f. japonica populations, a close relative of f. crenata, were examined. seven haplotypes were distinguishable in f. crenata based on nucleotide substitut ... | 2002 | 11920142 |
