Article Synopsis
- The genus L. is a herbaceous group in the Celastraceae family, comprising about 60 species primarily found in the Pan-Himalayan region, but its classification and evolutionary relationships are still debated.
- The study involved sequencing whole plastid genomes and nuclear ribosomal DNA of 48 species to re-evaluate the taxonomic standing of L. and investigate its phylogeny within Celastraceae.
- Results supported the Angiosperm Phylogeny Group IV classification, confirmed L. as a monophyletic group, and suggested that its diversification likely occurred during the Eocene, although morphological traits may have evolved multiple times, indicating possible hybridization/introgression that warrants further investigation.
The Qinghai-Tibetan Plateau (QTP) and adjacent areas are centres of diversity for several alpine groups. Although it is known that the QTP acted as a source area for diversification of the alpine genus , the evolutionary processes underlying diversity in this genus, especially the formation of narrow endemics, are still poorly understood. Hybridization has been proposed as a driver of plant endemism in the QTP but few cases have been documented with genetic data.
