Population genomics analysis of Grindelia squarrosa (Pursh) Dunal in Billings, Montana

Abstract

Given the rising impact of climate change and habitat modification, understanding the genetic mechanisms underlying plant adaptation is crucial for conservation efforts. This study investigates how different populations of Grindelia squarrosa (Pursh) Dunal, commonly known as curly-cup gumweed, adapt to diverse environmental conditions in Montana, a key to understanding plant adaptability and resilience. Using a population genomics approaches and next-generation sequencing the populations of desert vs mesic plants were explored to identify genetic variations that maybe linked to their environmental adaptations. This study is tested by the hypothesis: these populations are unique under different selective pressures, which will be detected at the genomic level, providing a clearer picture of how species respond to varied ecological pressures. These insights will advance our understanding in the field of conservation genomics and highlight the crucial role of genetic diversity and adaptation in facing environmental changes.
