Event details

A lecture in the Crop Systems Seminar Series, presented by Dr Lionel Dupuy of the James Hutton Institute. "I develop models that predict how crops utilise environmental resources to grow and produce yield. I design experimental systems where such processes can be observed and quantified. Recent work has focused on the development of novel transparent soils that are suitable for the culture and live imaging of soil biological organisms."

 

Abstract: Roots and their interactions with soil and microorganisms are important in nutrient uptake and disease transmission, but techniques for observing soil biological organisms in situ are lacking. In this talk, I will present new approaches developed in my lab to observe, image and characterize roots and microorganisms live an in situ. For example, we have developed a new substrate termed transparent soil that combines complex soil-like environment and the capabilities of imaging biological processes at different scales, resolutions and throughput rates using modern microscopy techniques. I will also present new approaches to understand root and soil physical interactions, including new micro-mechanical sensors, 3D imaging, image analysis and modelling.

Speaker information

Dr Lionel Dupuy,The James Hutton Institute,My research also focuses on quantitative imaging to improve data resolution and throughput for models. I use techniques such as Optical Projection Tomography (OPT), Single Plane Illumination Microscopy (SPIM, in collaboration with Mike MacDonald), Biospeckle Laser (BSL, in collaboration with Roberto Braga) and web-cam and scanner based systems to construct low cost high throughput phenotyping (Michael Adu, co-supervisors Martin Broadley, Malcolm Bennett, Philip White). The main objective is to construct simple models that can be understood, calibrated easily using available data and integrated with existing software. To achieve this objective, I develop continuous models (PDE) where fundamental growth processes can be incorporated explicitly into conservation equations (in collaboration with Glyn Bengough, Xavier Draye, Tim George and Philip White).
