Genetic diversity and taxonomic status of Pinus tabulaeformis f. shekanensis revealed by ISSR markers
Pinus tabulaeformis f. shekanensis is a rare taxon endemic in the Ziwuling Loess Plateau, of which only one population is known. Inter-simple sequence repeat molecular markers were employed to compare the taxon’s genetic diversity with its 4 nearest wild relatives (P. tabulaeformis, P. tabulaeformis var. mukdensis, P. massoniana, and P. henryi) to assess the taxonomic status of P. tabulaeformis f. shekanensis.
