Phylogenetics and Taxonomy of Melastomataceae

Melastomataceae represents one of the largest angiosperm families within the order Myrtales, comprising over 5 000 species across more than 170 genera and exhibiting its greatest diversity in tropical regions. Advances in molecular phylogenetics have transformed our understanding of generic limits and evolutionary relationships, integrating data from plastid genomes, nuclear ribosomal markers and target-capture approaches. These efforts have resolved major clades such as Sonerileae, Miconieae and Microlicieae, clarified the monophyletic status of core groups and exposed instances of rapid radiation that challenge conventional classification. Time-calibrated trees suggest a Paleogene origin in South America with multiple dispersal events to Asia, Africa and the Pacific, while morphological revision informed by phylogenomics has led to the recircumscription of several genera. This synthesis underpins taxonomic stability, informs conservation priorities in biodiversity hotspots and guides ecological restoration by providing a robust framework for species delimitation and biogeographical inference.

Phylogenetics and Taxonomy of Melastomataceae publication trend

The graph below shows the total number of articles in phylogenetics and taxonomy of melastomataceae across all publications each year (not limited to Nature Index journals).

Technical terms

Plastome: The complete sequence of the chloroplast genome, widely used for reconstructing plant phylogenies.

nrITS: Nuclear ribosomal internal transcribed spacer region, a multicopy marker employed to resolve relationships at genus and species levels.

Monophyly: A group of organisms comprising an ancestor and all its descendants, reflecting a single evolutionary lineage.

Target capture: A high-throughput sequencing method that enriches specific nuclear loci for phylogenomic analysis.

Divergence time estimation: Molecular dating techniques that assign ages to nodes in a phylogeny using fossil or secondary calibration points.
