Special Issue Information

Dear Colleagues,

Medicinal plants synthesize a broad array of bioactive compounds as defensive metabolites. The development of genetically elite varieties with desired traits under suitable environments is essential to secure the cultivation of high-quality herbs. With the aid of biotechnology tools, herb genomics has recently become an emerging field that investigates the molecular genetic basis of species identity and the beneficial traits in medicinal plants, particularly the biosynthesis and accumulation of phytopharmaceuticals using genomics, transcriptomics, and metabolomics data.

With the ever-increasing developments in the various biotechnological procedures, the research on the molecular genetics of medicinal plants has been tremendously deepened. In this Special Issue, we aim to focus on the molecular genetics of medicinal plants considering the genetic resources, genome differences, gene function, and their related research methods. The predominant research fields are species identification, molecular breeding, and the study of the biosynthesis of special active constituents. The research themes of molecular genetics of medicinal plants are classified as genetic resources, model platforms, synthetic biology, and molecular breeding, which give rise to hundreds of genome projects of medicinal and aromatic plants. Moreover, in the characterization of medicinal plant resources, we have the aid of model and mutant species and the breeding of new varieties of medicinal plants with a high content of active ingredients and a reliable resilience facing the stressor relying on the molecular markers and transgenes.

This Special Issue will focus on the prospects of the molecular genetics and resources of medicinal plants. Our aim is to compile the recent advances in any aspects of the molecular genetics and resources of medicinal and aromatic plants. We welcome original research and review articles on all relevant topics. Topics of interest include, but are not limited to, the following:

  • Molecular genetics methodologies;
  • Genetical analysis;
  • Marker-assisted breeding of medicinal plants;
  • Gene characterization and function;
  • Development and utilization of molecular genetics;
  • Genotyping technologies;
  • Genetic resources of medicinal plants;
  • Genetic analysis of specialty metabolites;
  • Gene structure and function analysis.

Paris polyphylla var. yunnanensis is a well-known medicinal plant that is mainly distributed in Southwest China; however, its genetic diversity and biodiversity processes are poorly understood. In this study, the sequences of cpDNA trnL-trnF fragments of 15 wild populations and 17 cultivated populations of P. polyphylla var. yunnanensis were amplified, sequenced, and aligned to study the population genetics of this species. Genetic diversity was analyzed based on nucleotide diversity, haplotype diversity, Watterson diversity, population-level diversity, and species-level genetic diversity. Genetic structure and genetic differentiation were explored using haplotype distribution maps and genetic distance matrices. A total of 15 haplotypes were identified in the 32 populations of P. polyphylla var. yunnanensis. Five unique haplotypes were identified from the fourteen haplotypes of the cultivated populations, while only one unique haplotype was identified from the ten haplotypes of the wild populations. The haplotype richness and genetic diversity of the cultivated populations were higher than those of the wild populations (HT = 0.900 vs. 0.861). In addition, there were no statistically significant correlations between geographic distance and genetic distance in the cultivated populations (r = 0.16, p > 0.05), whereas there was a significant correlation between geographical distance and genetic structure in the wild populations (r = 0.32, p > 0.05), indicating that there was a geographical and genetic connection between the wild populations. There was only 2.5% genetic variation between the wild populations and cultivated populations, indicating no obvious genetic differentiation between the wild and cultivated populations. Overall, the genetic background of the cultivated populations was complex, and it was hypothesized that the unique haplotypes and higher diversity of the cultivated populations were caused by the mixed provenance of the cultivated populations.
