G03012: Development of unified data models and data pre-processing strategies for the generation of meaningful, standardised statistical analyses of metabolome variability in crop plants

Thursday 9 February 2006

This project addresses the need to have baseline metabolomic data for crops, to use as a reference in assessing new crop varieties (GM or non-GM). It also addresses how the quality of the raw data used for assessment purposes may affect the safety assessment.

Study Duration : December 2005 to May 2008

Contractor : University of Wales, Aberystwyth

Background

A pilot study in G02006 showed that differences in data structure confounded statistical analyses aimed at producing a common understanding of metabolite baseline. The G02 programme involved 12 collaborating sites in six projects and produced metabolomics data for potato, wheat, barley, Arabidopsis and tomato. In the emerging field of metabolomics, no widely applied standards for experimental procedure are available and a range of analytical equipment has been used. Consequently, the large amount of data collected is not necessarily comparable. No prior arrangements were defined to ensure or enhance comparability of data from different projects.

This project aims to turn these disparate data, developed on different instruments using a range of standard operating procedures (SOPs), into a resource that will provide a meaningful and durable description of food raw material composition for any future safety or quality assessments.

This study will concentrate firstly on developing a standardised data format for each analysis method. It will then be possible to convert existing data into data tables that can be compared meaningfully in order to develop an understanding of the baseline metabolite content and variability in traditional crop varieties and cultivars. This resource will aid further safety assessment of any proposed GM releases. Additionally, it will provide a starting point for any assessment of quality, provenance, agronomic regime or post-harvest treatment associated with a food raw material.

Research Approach

This project has five major interacting objectives:
