ABSTRACT
Medicinal plant germplasm resources are the foundation of the modern development of traditional Chinese medicine. In-depth study of medicinal plant germplasm resources is a prerequisite for cultivating fine varieties and ensuring the output and standard quality of traditional Chinese medicine(TCM). Traditional identification methods start with appearance and are greatly affected by natural environment and human factors,with a low efficiency and accuracy of identification are generally low molecularin general. Due to such advantages as easy operation,high sensitivity,accurate results, molecular biology technology has been widely used in the related research of relevant studies for medicinal plant germplasm resources due to its advantages of easy operation,high sensitivity,accurate results,etc. It mainly involving the distinction between wild and cultivated products,researchstudy on substitutes of TCM,identification of Chinese patent medicine,good variety marker breeding,genetic diversity researchstudy,genetic map establishment and omics research,etcstudy. Among them,omics researchstudy is divided into genomics,transcriptomics,metabolomics,and proteomics due toby different analysis purposes. Genomics is divided into three sub-fields namely structural genomics,functional genomics, and comparative genomics. Eukaryotes Because eukaryotes have nuclei and organelles,so omics researchstudy also includes chloroplast genomics,mitochondrial genomics,nuclear genomics,and plastid genomics. Among them,the chloroplast genome has a simple structure,small molecular weight,and good conservation,while the mitochondrial genome has a strong variability and complex structure,the nuclear genome data isfeatures complex, data and the nucleus contains no ribosomes in nucleus,resulting in spatiotemporal differences in the translation process,even if repeated repeatedly test, the result of and the test is alsoresults remained uncertain, even after repeated tests. The molecular biology technology and omics researchstudy involved in theby current medicinal plant researchstudy still hashave shortcomings,and there iswith a large room for development,which needs and need further improvement and supplementation. This articlepaper successively introduces the characteristics and applications of cytology,molecular markers,and omics researchstudy techniques in the identification of medicinal germplasm resources,providingin order to provide a reference for subsequent identification,development and utilization of medicinal plant germplasm resources.
