Construction of a core collection of Notopterygii Rhizoma et Radix based on molecular phylogeography.

ABSTRACT:

Background

As endangered medicinal species (Category III protected plants in China) and as authentic traditional Chinese medicines, Notopterygium incisum Ting ex H. T. Chang and N. franchetii Boiss. require urgent conservation of their germplasm resources. While core collections offer an efficient solution for preserving genetic diversity, no such resource currently exists for these species despite their ecological and pharmacological importance.

Methods

In this study, three chloroplast DNA regions (rbcL, matK, and trnS-trnG) and the nuclear ribosomal ITS sequence were employed as molecular markers to conduct phylogeographic analyses of N. incisum and N. franchetii, and their core collections were constructed through stratified sampling of evolutionary significant haplotypes
