How should we turn data into decisions in AgriFood?
The AgriFood supply chain is under significant pressures related to food security, climate change, and consumer demands for affordable and higher quality food. Various technologies are already deployed producing a large amount of data, which can be utilised to guide decision-making to improve productivity, reduce wastage, and increase traceability across the AgriFood supply chain. Several examples of the use of data are given, including improving efficiency in livestock production, supporting automation and use of robotics in crop production, increasing food safety and evidencing its provenance. The opportunities and ways forward were discussed at a workshop in November 2017, run by the Society of Chemical Industry and the Knowledge Transfer Network in the UK. This paper presents a summary of the key messages from the presentations and focus-group discussions during this event, as interpreted by the authors. A number of challenges in digitalisation of the AgriFood supply chain are discussed, such as low inter-operability of different data sets, silo mentality, low willingness to share data and a significant skills gap. Various approaches are presented that could help to unlock the benefits of using data, from practical support to producers and addressing skills gaps, to industrial leadership and the role of government departments and regulatory bodies in leading by example. Looking forward, data are already revolutionising the AgriFood supply chain, however, the benefits will remain piecemeal until the leaders of today are able to bring together the disparate groups into a cohesive whole
Analysis of the phosphoproteome of the multicellular bacterium Streptomyces coelicolor A3(2) by protein/peptide fractionation, phosphopeptide enrichment and high-accuracy mass spectrometry
The serine (Ser)/threonine (Thr)/tyrosine (Tyr) phosphoproteome of exponentially growing Streptomyces coelicolor A3(2) was analysed using the gel-free approaches of preparative IEF for protein fractionation, followed by strong cation exchange peptide fractionation and phosphopeptide enrichment by TiO2 metal oxide affinity chromatography. Phosphopeptides were identified using LC-ESI-LTQ-Orbitrap™ MS. Forty-six novel phosphorylation sites were identified on 40 proteins involved in gene regulation or signalling, central metabolism, protein biosynthesis, membrane transport and cell division, as well as several of unknown function. In contrast to other studies, Thr phosphorylation appeared to be preferred, with relative levels of Ser, Thr and Tyr phosphorylation of 34, 52 and 14%, respectively. Genes for most of the 40 phosphorylated proteins reside in the central “housekeeping” region of the linear S. coelicolor chromosome, suggesting that in general Ser, Thr and Tyr phosphorylation play a role in regulating essential aspects of metabolism in streptomycetes. A greater number of regulators and putative regulators were also identified compared with other bacterial phosphoproteome studies, potentially reflecting the complex heterotrophic and developmental life style of S. coelicolor. This study is the first analysis of the phosphoproteome of a member of this morphologically complex and industrially important group of microorganisms
