Bottleneck: Quantitative and Molecular Genetics in Model Plants After Demographic Bottlenecks

Section(s): Plant Population Biology, Botany

Responsible staff: Guy Colling, Laura Daco

Research strategy: Understanding and Preserving Nature

The research project focuses on elucidating the complex relationship between quantitative genetics and molecular genetics in model plant species that have undergone significant demographic bottlenecks. Exploring the genetic diversity of these plants after bottleneck events aims to uncover crucial insights into their adaptive potential and resilience in the face of environmental challenges.

The project builds on the foundations laid by previous common‑garden experiments carried out with Anthyllis vulneraria, providing a solid framework for comparative analysis across several plant species. Building on this preliminary work, new common‑garden experiments will be conducted in Luxembourg.

An essential element of our approach is close collaboration with the Icelandic Institute of Natural History, drawing on their expertise and resources to deepen our understanding of the genetic landscapes of these model plants. Through this collaboration, the aim is not only to advance scientific knowledge but also to foster international partnerships in ecological and evolutionary research.

Overall, this project represents a multifaceted exploration of the complex interaction between genetic diversity and adaptability in plant species following bottleneck events, with implications for biodiversity conservation and ecosystem resilience.
