• A paradigm shift to root system engineering to improve resource capture and plant development under adverse conditions.

• Central to our approach is the use of tomato as a model species since it can be very easily grafted, allowing precise assessment of the effect of altering root traits on crop performance independently of shoot traits

• This project will identify genetic variation and quantitative trait loci (QTL) that allow tomato roots to confer crop resistance to a range of abiotic stresses, alone or in association with arbuscular mycorrhizal fungi (AMF) and/or plant growth promoting rhizobacteria (PGPR).
