Application of strigolactones to plant roots to influence formation of symbioses

Strigolactones play a potent role in the rhizosphere as a signal to symbiotic microbes including arbuscular mycorrhizal fungi and rhizobial bacteria. This chapter outlines guidelines for application of strigolactones to pea roots to influence symbiotic relationships, and includes careful consideration of type of strigolactones applied, solvent use, frequency of application and nutrient regime to optimize experimental conditions.
