Clock Genes and NuA4/TIP60 Complex Linked to Winter Diapause in Harmonia Axyridis

Quick Summary

• A study published in the Proceedings of the National Academy of Sciences (PNAS),Volume 122,Issue 28,July 2025,explores how circadian clock regulators impact seasonal polymorphisms,such as diapause,specifically in Harmonia axyridis.
• The research refines existing models by illustrating how both positive and negative regulators in circadian clocks demonstrate a canonical timekeeping function’s influence on biological processes.

Indian Opinion Analysis
This study contributes to global understanding of biological rhythms and their ecological significance. While specific to Harmonia axyridis, insights from this research could have broader implications for understanding similar mechanisms in organisms found within India’s rich biodiversity. India’s agricultural ecosystem heavily relies on managing pests and leveraging beneficial species. Enhanced knowledge about diapause regulation mechanisms may eventually provide solutions for enduring pest control strategies or conservation efforts for native species linked with agricultural productivity.
