Population genomics of helminth parasites

Area of Science:

• Evolutionary Biology
• Genomics
• Parasitology

Background:

• Next-generation sequencing (NGS) enables whole-genome studies, moving beyond targeted loci in population genetics.
• Parasitic helminths present diverse evolutionary and population biology questions.
• Current research often focuses on human parasites, overlooking broader helminth biodiversity.

Purpose of the Study:

• To review population genomics applications in understanding parasitic helminth biology and evolution.
• To highlight key research areas including parabiosis, hybridization, population structure, selection, and linkage mapping.
• To advocate for expanding population genomics to diverse helminth species.

Main Methods:

• Review of current literature and trends in parasitic helminth population genomics.
• Analysis of research questions addressable by whole-genome approaches.
• Identification of advances and limitations in the field.

Main Results:

• Population genomics is increasingly used to study helminth population structure, evolution, and adaptation.
• Significant advances have been made, but research is skewed towards human-associated parasites.
• Key topics include hybridization, selection, and linkage mapping in helminth populations.

Conclusions:

• Expanding population genomics to a wider range of helminth species is crucial.
• Broader application will enhance fundamental knowledge of helminth population biology and evolution.
• Comparative population genomic studies across helminth diversity can address broader ecological and evolutionary concepts.
