Metabolite profiling in plant biology: platforms and destinations

Optimal use of genome sequences and gene-expression resources requires powerful phenotyping platforms, including those for systematic analysis of metabolite composition. The most used technologies for metabolite profiling, including mass spectral, nuclear magnetic resonance and enzyme-based approaches, have various advantages and disadvantages, and problems can arise with reliability and the interpretation of the huge datasets produced. These techniques will be useful for answering important biological questions in the future

The potential of integrative phenomics to harness underutilized crops for improving stress resilience

The current agricultural and food system faces diverse and increasing challenges. These include feeding an ever-growing human population, expected to reach about 10 billion by 2050 combined with societal disruption, and the need to cope with the impact of climate change (FAO, 2022). Given that future environmental conditions will limit crop productivity (Zhao et al., 2017; Cooper et al., 2021) and the limited potential to continually increase the performance of staple crops by conventional breeding (Hickey et al., 2019), there is an urgent need to transform agricultural systems

Système d'élevage, un concept pour raisonner les transformations de l'élevage

Le concept de «système d’élevage» a été développé pour rendre compte et modéliser des interactions entre dimensions humaines et dimensions biotechniques de l’activité d’élevage. Après avoir rappelé l’origine et les bases des approches intégrées de l’élevage, et les applications centrées sur les liens décisions-pratiques-performances de troupeau, nous montrons comment ce concept évolue pour traiter des transformations de l’élevage, tant des attentes des éleveurs (pour un travail maîtrisé) que celles de la société (pour un plus grand respect de l’environnement). La problématique du développement durable appelle un renouvellement des approches des systèmes d’élevage vers l’étude des capacités adaptatives des systèmes socio-écologiques à l’échelle de territoires

Integrative analyses of genetic variation in enzyme activities of primary carbohydrate metabolism reveal distinct modes of regulation in Arabidopsis thaliana

Multiparallel QTL analysis of 15 Arabidopsis primary carbohydrate metabolism enzymes reveals that traits affecting primary metabolism are often correlated

High-throughput plant phenotyping: a role for metabolomics?

High-throughput (HTP) plant phenotyping approaches are developing rapidly and are already helping to bridge the genotype–phenotype gap. However, technologies should be developed beyond current physico-spectral evaluations to extend our analytical capacities to the subcellular level. Metabolites define and determine many key physiological and agronomic features in plants and an ability to integrate a metabolomics approach within current HTP phenotyping platforms has huge potential for added value. While key challenges remain on several fronts, novel technological innovations are upcoming yet under-exploited in a phenotyping context. In this review, we present an overview of the state of the art and how current limitations might be overcome to enable full integration of metabolomics approaches into a generic phenotyping pipeline in the near future.info:eu-repo/semantics/publishedVersio
