Construction of an identification system in considering molecular phylogeny and phytochemistry

为胡椒科胡椒属植物资源的开发利用奠定基础，尝试建立一套简便易用的鉴定体系。形态数据库已建立，但由于栽培材料条件不满意，仍未完成。一些化学物质，包括木脂素，被认为是鉴定分类群的潜在工具。构建了包含29个已知序列的69个OTU的分子系统发育树。整合所获得的信息正在进行中。

For the bases of development of plant resources in the genus Peperomia (Piperaceae), an easy-to-use identification system was tried to construct. Morphological database was prepared but still not completed due to unsatisfied condition of the material cultivated. Several chemicals including secolignan that are potential tool for the identification of taxa were recognized. And a molecular phylogenetic tree with 69 OTUs including 29 known sequences was constructed. Integration of the obtained information is on the way.
