Molecular Phylogeny and Taxonomic Insights for Premna (Lamiaceae) in Thailand
Introduction This article summarizes the molecular phylogeny and taxonomic notes for Premna (Lamiaceae) in Thailand, based on a multi-locus chloroplast approach. Utilizing four chloroplast markers and concatenated datasets, the study delineates phylogenetic relationships among Thai Premna species, highlights unresolved polytomies, and revisits trusted species concepts within the P. serratifolia complex. Phylogenetic reconstruction Using a multi-locus…

Molecular Phylogeny and Taxonomic Notes on Premna (Lamiaceae) in Thailand
Overview This study provides the first multi-locus phylogenetic framework for Premna species in Thailand, using four chloroplast markers. The results corroborate a monophyletic Premna within Premnoideae and its sister relationship to Gmelina L., while highlighting unresolved nodes within the Thai Premna lineage that require deeper genomic analyses. Phylogenetic framework and key findings Using four chloroplast…

Comparative Chloroplast Genomics of Erigeron (Asteroideae, Asteraceae): Insights into Evolutionary Relationships and Phylogeography
Introduction: Erigeron’s Global Footprint and the Chloroplast View The genus Erigeron, commonly known as fleabanes, comprises hundreds of species distributed across temperate and mountainous regions worldwide. Despite its ecological versatility and near-cosmopolitan range, resolving Erigeron’s evolutionary relationships has been hampered by polyphyly, hybridization, and taxonomic ambiguity, especially among Old World taxa. Chloroplast (cp) genomes, with…

Comparative Chloroplast Genomics of Erigeron (Asteroideae, Asteraceae): Insights from a Broad Phylogenomic Survey
Overview: Why Compare Erigeron Chloroplast Genomes? Erigeron, commonly known as fleabanes, includes hundreds of species spread across temperate and mountainous regions worldwide. Unraveling their evolutionary relationships is challenging due to polyphyly, hybridization, and taxonomic ambiguity, especially among Old World taxa. A comprehensive comparative study of chloroplast (cp) genomes provides a stable, maternally inherited genetic framework…
