S20/19 Mycorrhizal Symbiosis -The Incredible Relationship of Fungi and Plants

Wednesday, March 11, 2020
6:00pm – 8:00pm

Tolland County Agricultural Center, 24 Hyde Ave Vernon, CT 06066

In this class we will explore the incredible symbiotic relationship between plants and fungus in the soil. A vast majority of plants utilize this association which has evolved over hundreds of millions of years. The fungus provides the host plant with nutrients, such as phosphate and nitrogen, and increases the abiotic and biotic stress resistance of the host. In return for these benefits, the host plant transfers some of its photosynthetically fixed carbon to the fungus This relationship is essential for many plants, some oaks, pines, and all orchids require this association. We will present an overview of Mycorrhizal symbiosis by covering both AM and EM mutualisms in a compare and contrast format so people can come away with a broad understanding of plant/fungal interrelationships We will also cover some adaptations that plants have made to exploit these fungi, with some plants not being able to photosynthesize and just getting their nutrients from the fungus.
