Role Of Heme Oxygenase In Modulating Expression Of Ros-Regulatory Enzymes In Medicago Truncatula, Parna Ghosh
Role Of Heme Oxygenase In Modulating Expression Of Ros-Regulatory Enzymes In Medicago Truncatula, Parna Ghosh
Graduate College Dissertations and Theses
Heme Oxygenase (HO) is an enzyme universally found in animals, plants and microbes. In plants, the role of heme oxygenase in the synthesis of the phytochrome chromophore is well recognized and has been extensively studied; however its role in regulating reactive oxygen species (ROS) in plants is just beginning to be explored, particularly in legumes. Legumes interact with Rhizobium bacteria to form symbiotic nitrogen fixing nodules. ROS plays an important role in the development of roots as well as symbiotic nodules. In the model legume Medicago truncatula, ROS in the root is regulated in part by the LATD/NIP gene. …

Investigations Into Host-Specific Interactions And Local Adaptation In The Mycorrhizal Symbiosis, Jonathan Gonzalez
Graduate College Dissertations and Theses
Mycorrhizal fungi are soil-borne organisms that form symbiotic associations with the majority of land plants. These fungi gather and exchange mineral nutrients with plants for photosynthetically derived carbohydrates. Mycorrhizal fungi can also confer other benefits onto plants, e.g. defense against pathogens, improved water relations, tolerance to heavy metal toxicity and herbivory. The influence of mycorrhizal fungi on plant mineral nutrition and response to stress suggests that these organisms may have a role to play sustainable agriculture as well as in bioremediation and ecosystem restoration.
In contributing to this important research, I investigated host-specific interactions between mycorrhizal fungi and the sex …
