Plant growth is often limited by nutrient deficiency and plants have evolved symbioses with microbes to access previously unavailable soil nutrients. Leguminous plants are unique as they form a symbioses with both rhizobial soil bacteria, leading to nitrogen-fixing nodules, and arbuscular mycorrhizal symbiosis with soil fungi to access nutrients such as phosphate. Recently, we have discovered the new plant hormone strigolacatone, which is essential for mycorrhizal development, also regulates nodulation.
My project aims to advance our understanding of how plants establish and regulate these important symbioses by defining the role of plant-derived hormones, particularly strigolactones. My project explores the development of these symbioses in a series of well-characterised pea mutants with altered hormone synthesis or perception, and includes whole plant physiology, gene expression studies and hormone quantification.
