Multiple roles of flavonoids in plant-rhizobia symbioses and plant-pathogen interactions

Hassan, Samira

Description

Flavonoids are secreted by plant roots to activate and attract nitrogen-fixing bacteria known as rhizobia. Rhizobia perceive flavonoids and reciprocate with secretion of nod-factors required to initiate nodule organogenesis. In this thesis I have explored the roles flavonoids play in roots during early nodulation of Medicago truncatula. To achieve this goal, I silenced or overexpressed genes encoding key enzymes in the flavonoid biosynthesis pathway in hairy-root cultures. I used...[Show more]
