Abstract
Abies delavayi subsp. fansipanensis (Xiang Q.P.) Rurhforth) or Abies delavayi var. nukiangensis auct.nonis a native plant, distributes at altitudes about 2,400 m above sea level. This plant belongs to the Pinaceae family and is listed in endangered, precious and rare species banned from commercial exploitation. The Abies delavayi subsp. fansipanensis population in Vietnam only concentrates in a mountainous area at the peak of Fansipan with a population diameter of about 3 km at an altitude of 2,600 to 2,950 m, and is about 500 km far from the Abies delavayi population in Cang Shan (China). In this study, the author sequenced the region of the rbcL and trnH-psbA of Abies delavayi subsp. fansipanensis in Vietnam, compared with the Abies delavayi of China to better understand the genetic characteristics of Abies delavayi subsp. fansipanensis in Vietnam. The results showed that the Abies delavayi subsp. fansipanensis in Vietnam has a different nucleotide position compared to the Chinese Abies nukiangensis at nucleotide no. 455 on the rbcL gene region and two other nucleotide positions in the trnH-psbA genome at positions 332 and 503. The sequences of the rbcL and trnH-psbA gene regions of Abies delavayi subsp. fansipanensis from Vietnam were registered into the GenBank with the accession number MK783132 and MK783131, respectively.
