Isolation and Characterization of Microsatellite Loci from Pinus Massoniana (Pinaceae)

馬尾松(松科)微衛星基因座的分離及分析

摘要


馬尾松廣泛分布於中國大陸中部以及東部地區,但在台灣因棲地破壞以及松樹萎凋病的影響而僅存單一現生族群。本研究意欲分離馬尾松微衛星基因座以利未來能應用於探討馬尾松族群遺傳結構,結果顯示共分離出11組可用的微衛星基因座,進一步分析顯示在馬尾松中此11組微衛星基因座其對偶基因數目為2到9個;異質度觀測值(Ho)介於0.00到0.82;然而異質度期望值(He)則為0.40到0.83,此些馬尾松微衛星基因座將可提供一工具來探討台灣以及中國大陸馬尾松族群的遺傳結構。

Pinus massoniana is widespread in the central and eastern mainland China, while distributed in Taiwan with a single population. This island population has been declining due to habitat destruction and pine wilt disease. In the study we isolated microsatellite loci from P. massoniana for investigating the population structure. Eleven, novel microsatellite markers were developed from P. massoniana by using a modified PCR-based isolation of microsatellite arrays (PIMA) method. The number of alleles, observed and expected heterozygosities across loci varied with a range of 2-9, 0.00-0.82 and 0.40-0.83, respectively. The application of these microsatellite markers of P. massoniana provides a tool for understanding demography and population structure in Taiwan and mainland China.
