Implication

Exploratory analysis reveals genetic dynamics and diversity in Thymus sect. Mastichina, suggesting conservation needs.

Key Points

  • This study aims to understand the gene flow between diploid and tetraploid groups within the polyploid complex of Thymus sect. Mastichina.
  • Used Hyb-Seq data for phylogenomics and population genomics analysis.
  • Identified genetic structures among diploid and tetraploid groups.
  • Conducted phylogeographic analyses to assess genetic differentiation.
  • Examined patterns of interploidy introgression among lineages.
  • Confirmed the presence of two sister groups of distinct ploidy levels.
  • Identified four distinct diploid subgroups with complex genetic structuring.
  • Detected low genetic differentiation in the tetraploid group, indicating rapid expansion.
  • Confirmed interploidy gene flow, suggesting admixture despite geographic isolation.
