Findings from W. Zeng and Co-Authors Provide New Insights into Agriculture and Food Chemistry

June 26, 2014

By a News Reporter-Staff News Editor at Food Weekly News -- Investigators discuss new findings in Agriculture and Food Chemistry. According to news reporting from Wilmington, Delaware, by VerticalNews journalists, research stated, "Profiling techniques such as microarrays, proteomics, and metabolomics are used widely to assess the overall effects of genetic background, environmental stimuli, growth stage, or transgene expression in plants. To assess the potential regulatory use of these techniques in agricultural biotechnology, we carried out microarray and metabolomic studies of 3 different tissues from 11 conventional maize varieties."

The news correspondents obtained a quote from the research, "We measured technical variations for both microarrays and metabolomics, compared results from individual plants and corresponding pooled samples, and documented variations detected among different varieties with individual plants or pooled samples. Both microarray and metabolomic technologies are reproducible and can be used to detect plant-to-plant and variety-to-variety differences. A pooling strategy lowered sample variations for both microarray and metabolomics while capturing variety-to-variety variation. However, unknown genomic sequences differing between maize varieties might hinder the application of microarrays. High-throughput metabolomics could be useful as a tool for the characterization of transgenic crops."

According to the news reporters, the research concluded: "However, researchers will have to take into consideration the impact on the detection and quantitation of a wide range of metabolites on experimental design as well as validation and interpretation of results."
