Anting Zhu et al. establish an approach to identify metabolites and their corresponding genes and pathways in wheat. https://doi.org/10.1093/plcell/koad286 By A. Zhu, M. Liu, Z. Tian, W. Liu, W. Chen et al.  National Key Laboratory of Crop Genetic Improvement and National Center of Plant Gene…

Cellular metabolism involves flux through metabolic routes, which can be measured using stable isotope (13C,15N) tracers. High-resolution mass spectrometry (HRMS) and transient isotope labeling studies offer an opportunity to get an in-depth understanding of metabolism in specific contexts. In this new…

Plants produce many specialized metabolites that are often associated with increased plant fitness. Metabolic genome wide association studies (mGWAS) identify enzymes involved in specialized metabolite biosynthesis. However, this relies on identifying metabolites from mass spectrometry data which is…

With atmospheric CO2 levels increasing 100 times faster than historical levels, much attention has been paid to how crop plants respond to this elevated CO2 (eCO2). For angiosperms, eCO2 leads to increased CO2 assimilation and decreased photorespiration, but over time plants can adapt, leading to lower…

Gordon et al. report that knock-out of a recently discovered enzyme for salicinoid biosynthesis in poplar leads to changes in salicylic acid and jasmonic acid metabolism and has unexpected effects on growth..

Breeding for flavor in fruits and vegetables is a dauting task. For several years, scientists have relied on consumer panels and instrumental analysis to make judgment calls on the flavor phenotype to select for during a breeding process. While these methods are often accurate and reliable, they are…
