Genome Size Constraints on Plant Ecology and Distribution

Explore the fascinating world of plant genome size and its ecological implications in this lecture by Professor Andrew Leitch. Discover how the amount of DNA in plant cells varies dramatically between species and learn about its profound effects on plant ecology and distribution. Examine long-term nutrient experiments from various locations worldwide that demonstrate how species with larger genomes thrive in nitrogen and phosphate-rich environments. Gain insights into how genome size influences plant communities based on factors such as nutrients, temperature, and precipitation. Delve into topics including genome downsizing, evolutionary selection, DNA repair pathways, and the prevalence of polyploidy in plants. Engage with audience questions that further illuminate the complex relationships between genome size, plant ecology, and evolution.
