Summary

The Moraceae, or mulberry family, encompasses over 1,000 species across 40 genera, including ecologically and economically important groups such as Ficus (figs), Morus (mulberries) and Artocarpus (breadfruits and jackfruits). Phylogenetic analysis in this family integrates nuclear and plastid sequence data, genome skimming and target capture to reconstruct evolutionary relationships, estimate divergence times and trace biogeographic histories. Such studies have revealed frequent instances of incomplete lineage sorting and reticulation, reflecting hybridisation and rapid radiations, particularly in tropical clades. Chloroplast genomes have proved highly conserved in structure yet rich in mutational hotspots, while nuclear markers such as the internal transcribed spacer and low-copy nuclear genes resolve deeper splits and reticulate events. Combined morphological and molecular approaches have prompted the recircumscription of non-monophyletic taxa, clarified species boundaries and shed light on the timing of major lineage divergences in the Miocene and earlier. These insights underpin conservation priorities, sustainable utilisation of fruit and timber species and a better understanding of plant diversification in tropical ecosystems.

Phylogenetic Analysis of Moraceae Species publication trend

The graph below shows the total number of articles in phylogenetic analysis of moraceae species across all publications each year (not limited to Nature Index journals).

Technical terms

Phylogenetics: Study of evolutionary relationships among organisms based on genetic or morphological data.

Chloroplast genome: The circular DNA within plant plastids used to infer maternal lineages and evolutionary history.

Hyb-Seq: A targeted sequencing approach combining hybridisation capture with high-throughput sequencing to retrieve hundreds of nuclear genes.

Incomplete lineage sorting: Persistence of ancestral genetic variants across successive speciation events, leading to discordance between gene trees and species trees.

Reticulation: Evolutionary process involving hybridisation or horizontal gene transfer that produces network-like relationships among taxa.

About these summaries

This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
