By a News Reporter-Staff News Editor at Proteomics Weekly -- A new study on Protein and Peptide Research is now available. According to news reporting out of Egham, United Kingdom, by NewsRx editors, research stated, "A key global challenge for plant biotechnology is addressing food security, whereby provision must be made to feed 9 billion people with nutritional feedstuffs by 2050. To achieve this step change in agricultural production new crop varieties are required that are tolerant to environmental stresses imposed by climate change, have better yields, are more nutritious and require less resource input."
Our news journalists obtained a quote from the research from the University of London, "Genetic modification (GM) and marker-assisted screening will need to be fully utilised to deliver these new crop varieties. To evaluate these varieties both in terms of environmental and food safety and the rational design of traits a systems level characterisation is necessary. To link the transcriptome to the metabolome, quantitative proteomics is required. Routine quantitative proteomics is an important challenge. Gel-based densitometry and MS analysis after stable isotope labeling have been employed. In the present article, we describe the application of a label-free approach that can be used in combination with SDS-PAGE and reverse-phase chromatography to evaluate the changes in the proteome of new crop varieties."
According to the news editors, the research concluded: "The workflow has been optimised for protein coverage, accuracy and robustness, then its application demonstrated using a GM tomato variety engineered to deliver nutrient dense fruit."
