MetabolomicsDecreased abundance of type III secretion systeminducing signals in Arabidopsis mkp1 enhances resistance against Pseudomonas syringae
Genes encoding the virulence-promoting type III secretion system (T3SS) in phytopathogenic bacteria are induced at the start of infection, indicating that recognition of signals from the host plant initiates this response. However, the precise nature of these signals and whether their concentrations...

MetabolomicsLinking root exudates to functional plant traits
Primary and secondary metabolites exuded by plant roots have mainly been studied under laboratory conditions, while knowledge of root exudate patterns of plants growing in natural communities is very limited. Focusing on ten common European grassland plant species, we asked to which degree exuded me...

MetabolomicsA general non-self response as part of plant immunity
Plants, like other multicellular lifeforms, are colonized by microorganisms. How plants respond to their microbiota is currently not well understood. We used a phylogenetically diverse set of 39 endogenous bacterial strains from Arabidopsis thaliana leaves to assess host transcriptional and metaboli...

MetabolomicsInhibition of jasmonic acid-isoleucine conjugating enzyme JAR1 shifts the local and systemic leaf signals and metabolic profiles in Arabidopsis

• Jasmonates (JAs)-mediated pathways are central signaling hubs in plant defense responses. However, the identification of mobile and non-mobile signals involved in downstream systemic signaling is still less studied.

• Here, we investigate the role of the jasmonic acid-isoleucine conjugati...

MetabolomicsPlant elicitor peptide signalling confers rice resistance to piercing-sucking insect herbivores and pathogens
Rice is a staple food crop worldwide, and its production is severely threatened by phloem-feeding insect herbivores, particularly the brown planthopper (BPH, Nilaparvata lugens), and destructive pathogens. Despite the identification of many BPH resistance genes, the molecular basis of rice resistanc...

MetabolomicsMetabolomic insights into the impact of cooking technologies on plant-based burger composition

This study evaluated the impact of different cooking methods (air frying, grilling, oven baking, and microwave cooking) on the chemical profile of chickpea-based burgers. For this purpose, an untargeted metabolomics approach was employed using ultra-high-performance liquid chromatography coupled ...

MetabolomicsSelection strengthens the relationship between plant diversity and the metabolic profiles of Plantago lanceolata

• Plant species diversity enhances community productivity, but how plant diversity impacts the metabolome of individual plants and the underlying eco-evolutionary processes remains unclear. This study investigated how plant species diversity and selection for growing in different diversity enviro...

MetabolomicsMaize Recruits Beneficial Microorganisms via Rhizosphere Metabolites as Signals to Construct a Functional Network for Saline-Alkaline Stress Resistance

Carbonate-type saline-alkaline stress severely constrains maize production; however, the synergistic response mechanisms between rhizosphere microorganisms and metabolites remain unclear. This study focused on maize fields in the carbonate chernozem region of the Songnen Plain in Northeast China....

MetabolomicsCo-exposure of di(2-ethylhexyl) phthalate (DEHP) decreased the submicron plastic stress in soil-plant system

The widespread use of agricultural plastic films has made micro- and nanoplastics (MNPs) and phthalate esters (PAEs) contaminants of emerging concern in agroecosystems. However, the interactive mechanisms underlying their combined pollution in soil-plant systems remain elusive. To fill this gap, ...
