ABSTRACT

Soil resources plants require are often distributed in a highly heterogeneous pattern. To aid foraging, root growth and development is highly responsive to soil signals. As a result, root architecture is shaped by myriad environmental signals to ensure resource capture is optimised. Non-invasive X-ray microCT imaging has revealed soil-water contact profoundly impacts root architecture. Novel root adaptive responses revealed using microCT include hydropatterning and xerobranching, where lateral roots form only when in direct contact with moisture. I will describe how the hydropatterning response requires core components of the auxin signalling machinery to be controlled via an environmentally regulated post-translational modification to pattern root branching.
