The paper links wood chemical traits to esca susceptibility and wood degradation in grapevines, showing that susceptibility is more related to wood degradability and metabolic responses than microbial communities.

The paper investigates how intraspecific variation in physiological strategies affects susceptibility to esca in grapevine cultivars, finding that conservative water use strategies reduce susceptibility while metabolic responses vary with disease symptoms.

This study shows that benzoxazinoids exuded by maize roots are taken up by rice roots, triggering chromatin changes and systemic chemical defense that reduce rice blast disease.

This study examines how heat stress affects transgenerational metabolic and phenotypic changes in Limosella australis, showing some metabolic persistence but no adaptive advantage in the next generation.

The paper identifies heat-associated metabolite markers in green grape berries using LC-MS and GC-MS, revealing cultivar-specific and common responses to high temperature.

This study uses predictive metabolomics to link plant biochemical diversity with ecological strategies and physiological traits across 74 species.

The paper investigates how drought and esca disease affect grapevine wood interactions with fungi, finding shared stress responses and distinct fungal adaptations under each condition.

This study uses multi-omics analysis of maize near-isogenic lines to identify QTLs associated with chilling tolerance and uncover regulatory and metabolic signatures.

This study uses paleometabolomics to analyze rodent middens over 50,000 years, showing how abiotic factors influence metabolic diversity and climate tracking through metabolite patterns.

The paper shows that root-root interactions in durum wheat mixtures delay foliar defense responses to Septoria tritici blotch, increasing susceptibility.

This study uses predictive metabolomics to identify leaf metabolic signatures linked to floral traits in Camellia, finding distinct metabolite sets for flower colour and form with higher prediction accuracy for colour.

The paper investigates how root phenolics mediate reduced disease susceptibility in wheat mixtures by disrupting root interactions and analyzing transcriptomic and metabolomic responses.

This study shows that nitrogen nutrition levels affect esca disease incidence in grapevines by altering physiology, metabolism, and transpiration, with deficiency reducing disease and excess increasing it.

This study investigates how grapevine cells adapt to carbon deficiency by analyzing transcriptome and methylome changes under varying glucose conditions.

The paper examines how rhizosphere chemistry and bacterial communities respond to environmental stress gradients in the Atacama Desert, identifying metabolic biomarkers and their ecological implications.
