Rangewide Population-Level Variation of Whitebark Pine (Pinus albicaulis) Using Full-Chloroplast Genomes.
The ecologically important whitebark pine is currently threatened by white pine blister rust, however, efforts to screen for blister rust resistant individuals are proceeding without input on where diversity exists. In this study, we use massively parallel sequencing to analyze whole chloroplast genomes (cpDNA) of 8 individuals from across the range. We found a total of 69 segregating sites (35 SNPs, 22 cpSSRs, 12 Indels), roughly evenly spaced across the genome. The pairwise-distance of P. albicaulis (0.000095) is intermediate among a set of intraspecific comparisons in other selected pines. Preliminary results suggest that extreme Northern populations have increased diversity relative to Southern populations, warranting further exploration. Ongoing research will provide important information toward conservation of this valuable species.
