Open questions: what are the genes underlying antagonistic coevolution?

Area of Science:

• Evolutionary biology
• Genetics
• Population genetics

Background:

• Coevolution, the reciprocal evolutionary change between interacting species, was conceptualized 150 years ago.
• The genetic underpinnings of coevolutionary processes remain largely unknown.
• Distinguishing between coevolutionary models requires knowledge of the responsible genes.

Purpose of the Study:

• To highlight the importance of identifying genes driving coevolutionary interactions.
• To emphasize the potential of such discoveries for advancing evolutionary and genomic sciences.

Main Methods:

• This study is a conceptual review and does not involve new experimental data.
• It synthesizes existing knowledge on coevolution and genetic mechanisms.

Main Results:

• The genetic basis of coevolution is currently poorly understood.
• Identifying genes involved in coevolution is a critical, yet unmet, research goal.

Conclusions:

• Identifying genes responsible for coevolutionary interactions is a milestone for population genetics and genomics.
• Such discoveries will enable differentiation between major coevolutionary models.
