Summary
Genetic diversity in Chrysosplenium was investigated using SRAP markers to assess wild resources. This study provides a foundation for the identification and protection of these valuable medicinal plants.
Area of Science:
- Botany
- Genetics
- Medicinal Plant Research
Background:
- Wild resources of Chrysosplenium, a traditional Chinese medicinal material, are declining.
- Urgent need for genetic resource investigation and protection research for Chrysosplenium.
Purpose of the Study:
- To investigate the genetic polymorphism and clustering of 24 Chrysosplenium species.
- To establish DNA digital fingerprints for unique molecular identification.
- To provide a basis for germplasm resource identification, protection, and utilization.
Main Methods:
- Investigated wild resources of 24 Chrysosplenium species (36 samples).
- Employed the SRAP (Sequence-Related Amplified Polymorphism) technique for genetic analysis.
- Utilized biological software for population genetic parameter analysis and UPGMA cluster analysis.
Main Results:
- Obtained 374 polymorphic bands using 18 SRAP primer pairs.
- Calculated genetic parameters: N_a = 2.0000, N_e = 1.4084, Nei's index = 0.2635, Shannon index = 0.4191.
- Clustered samples into three major groups based on genetic similarity, aligning with geographical and ecological distribution.
Conclusions:
- SRAP technique effectively revealed genetic diversity and relationships within Chrysosplenium species.
- Established unique DNA digital fingerprints for each sample, aiding identification.
- Findings support effective conservation strategies and future utilization of Chrysosplenium germplasm resources.
