Chamaecyparis formosensis is an endemic species of Taiwan, threatened from intensive use and illegal felling. An individual identification system for C. formosensis is required to provide scientific evidence for court use and deter illegal felling. In this study, 36 polymorphic simple sequence repeat (SSR) markers were developed. By applying up to 28 non-linkage of the developed markers, it is calculated that the cumulative random probability of identity (CPI) is as low as 1.652×10-12, the combined power of discrimination (CPD) is as high as 0.999999999998348, and the identifiable population size is up to 60 million, which is greater than the known C. formosensis population size in Taiwan. Biogeographical analysis data show that C. formosensis from four geographic areas belong to the same genetic population which can be further divided into three clusters: SY (Eastern Taiwan), HV and GW (Northwestern Taiwan), and MM (Southwestern Taiwan). The developed system was applied to assess the provenance of samples with 88.44% of accuracy rate, and therefore can serve as a pre-screening tool to reduce the range required for comparison. The system developed in this study is a potential crime-fighting tool against illegal felling. |
