Genetic Control of Root Architecture, Physiology and Disease Resistance Traits

Objective(s):
To improve our current understanding of the genetic control of processes implicated in architectural, physiological and disease resistance features of root systems
Genetic research on plant systems has largely focused on traits measured above ground leaving important rhizospheric traits virtually undiscovered. Understanding the mechanisms and genetic control of root traits will greatly benefit the genetic improvement of a wide range of crops. This workshop will summarize our current understanding of the genetic control of processes implicated in architectural, physiological and disease resistance features of root systems including adventitious rooting, basal root elongation, basal root-growth angle, lateral rooting, active nutrient uptake, drought tolerance, tolerance to submergence and salt stress, and resistance to soil borne root diseases as affected by environmental conditions.
