MetabolomicsPlant species richness promotes the decoupling of leaf and root defence traits while species-specific responses in physical and chemical defences are rare

The increased positive impact of plant diversity on ecosystem functioning over time is often attributed to the gradual accumulation of mutualists and dilution of antagonists in diverse plant communities. While increased plant diversity alters traits related to resource acquisition, it remains unc...

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...

MetabolomicsThe glycosyltransferase UGT76B1 modulates N-hydroxy-pipecolic acid homeostasis and plant immunity
The trade-off between growth and defense is a critical aspect of plant immunity. Therefore, the plant immune response needs to be tightly regulated. Salicylic acid (SA) is an important plant hormone regulating defense against biotrophic pathogens. Recently, N-hydroxy-pipecolic acid (NHP) was identif...

MetabolomicsComprehensive metabolomics reveals defence-driven metabolic reprogramming via withanoside biosynthesis under insect herbivory in Withania somnifera

Plants exhibit dynamic physiological and biochemical responses to herbivory that often involve extensive metabolic reprogramming. Withania somnifera (Ashwagandha), a globally important medicinal plant, is susceptible to herbivory by the pest Henosepilachna vigintioctopunctata, resulting in signif...

MetabolomicsCommon mycelial network modulates neighbour-primed plant defences against foliar pathogens by co-opting distinct inter-plant metabolic and biotic stress responses
This study contains raw and processed mass spectrometry-based metabolomics data from Medicago truncatula plants used to investigate inter-plant signalling through arbuscular mycorrhizal fungal common mycelial networks. The experiment examined metabolomic responses in receiver plants following stress...

MetabolomicsHow Does the Seed Pre-germinative Metabolism Fight against Imbibition Damage? Emerging Roles of Fatty Acid Cohort and Antioxidant Defence

During seed imbibition, lipids are engaged in membrane reorganization while facing free radical-mediated oxidative injury. In the present work, we explored changes in lipid components at different timepoints of imbibition (0.5, 2, 4, 6, and 8 h) in the legume Medicago truncatula, by combining bio...

MetabolomicsGhPsbO breaks the growth-immunity trade-off by simultaneously promoting growth and defence
The evolutionarily conserved trade-off between pathogen resistance and crop yield remains a major bottleneck in agricultural breeding. Although numerous genes governing disease resistance or growth productivity have been identified, the pleiotropic regulatory factors that harmonize these two agronom...

MetabolomicsDiurnal Dynamics Shape Plant Defense Responses: Temporal Variations in Disease Progression and Metabolic Reprogramming in Brassica oleracea
Plants synchronize their immune responses with the circadian cycle, yet the impact of diurnal timing on disease resistance remains poorly understood in crop species. In this study, we investigated how diurnal variation modulates defense responses in Brassica oleracea against Xanthomonas campestris p...

ProteomicsDistinct branches of the N-end rule pathway modulate the plant immune response
The N-end rule pathway is a highly conserved constituent of the ubiquitin proteasome system, though little information exists regarding biological roles. Here we show that the cysteine (Cys-) and glutamine (Gln)-specific amino-terminal (Nt)-amidase NTAQ1 branches are both components of the plant imm...

MetabolomicsMaize Stem Response to Long-Term Attack by Sesamia nonagrioides
Plants defend themselves against herbivores by activating a plethora of genetic and biochemical mechanisms aimed at reducing plant damage and insect survival. The short-term plant response to insect attack is well understood, but less is known about the maintenance of this response over time. We per...
