Revealed in accurate detail, the underground world of plants

n the soil much more effectively than previous techniques. The detailed accurate root architecture can then be seen in three dimensions.

Tony Pridmore, Data Director at CPIB and an expert in tracking and analysis software, said: "Thinking of Micro-CT data as a sequence of images allows us to solve the problems caused by variations in the appearance of plant roots and the similarity of some roots to the surrounding soil. This is important because we can now extract descriptions of root architecture quickly and objectively."

Malcolm Bennett, Professor of Plant Sciences and an expert in root biology, said: "Root architecture critically influences nutrient and water uptake. A key impediment to genetic analysis of root architecture in crops grown in soil has been the ability to image live roots. Recent advances in microscale X-ray Computed Tomography (MicroCT) and RooTrak software at Nottingham now make this possible."

Ambitious project wins a further 3m in funding

The team has just been awarded a 3.5m (nearly 3m) five year European Research Council (ERC) Advanced Investigator Grant to use this new software in conjunction with an innovative microCT-based imaging approach to image wheat roots and select for new varieties with improved water and nutrient uptake efficiencies.

This ambitious project will be undertaken by a multidisciplinary team of scientists in the Centre for Plant Integrative Biology (CPIB) led by Professor Bennett. To undertake this research project help from collaborators across Europe, Mexico and Australia is also required to ensure that the most advanced techniques and biological resources are exploited to radically impact efforts to improve crop performance.
