Plant and Microbial Biology Plant Seminar: "Reprogramming root cells for AM symbiosis"
Seminar | November 1 | 12-1 p.m. | 101 Barker Hall
Maria Harrison, Cornell University
Most vascular flowering plants are able to form symbiotic associations with arbuscular mycorrhizal (AM) fungi. These associations, named arbuscular mycorrhizas, develop in the roots, where the fungus colonizes the cortex to access carbon supplied by the plant. The fungal contribution to the symbiosis includes the transfer of mineral nutrients, particularly phosphorus, from the soil to the plant. In many soils, phosphate exists at levels that are limiting for plant growth. Consequently, additional phosphate supplied via AM fungi can have a significant impact on plant development, and this symbiosis influences the structure of plant communities in ecosystems worldwide.
