The paper investigates how landscape complexity and management practices affect natural enemy distribution in Corsican citrus orchards, finding that organic farming and landscape heterogeneity support greater biodiversity.

A plant immune receptor mediates tritrophic interactions by linking caterpillar detection to predator recruitment

The paper shows that a plant immune receptor detects caterpillar oral secretions and triggers volatile emissions that attract predatory wasps, linking plant immunity to tritrophic interactions.

Common, species-specific, and accession-specific responses of foliar phytohormones and morphological traits to drought and herbivory

This study examines common and species-specific responses of phytohormones and morphological traits to drought and herbivory in three plant species, revealing shared and unique regulatory pathways.

Aphids capture plant inter- and intraspecific chemodiversity

This study shows aphids can capture plant inter- and intraspecific chemodiversity through their diet, with up to 93% of their chemical features matching those in plants.

Growth-promoting rhizobacteria amend the defense of strawberry plants against sequentially attacking herbivores

This study shows that plant-growth-promoting rhizobacteria enhance strawberry plant defense against sequential herbivore attacks by increasing secondary metabolites and improving plant physiology.

Extracellular ssDNA from Pittosporum tobira Exerts Strong Insecticidal Activity on Coccus hesperidum: a natural parallel to 'genetic zipper' technology

This paper demonstrates that extracellular single-stranded DNA from Pittosporum tobira has insecticidal activity against Coccus hesperidum and shows a natural parallel to genetic zipper technology.

Eavesdropping roots: Fagus sylvatica detects belowground stress signals from conspecific and heterospecific (Picea abies) neighbors, triggering increased shoot VOC emissions

This study shows that Fagus sylvatica detects belowground stress signals from Picea abies neighbors, leading to increased shoot VOC emissions, with stronger responses in heterospecific pairs.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene-dependent expression

The paper investigates whether plant defences persist in detached tomato leaves and finds that gene expression increases over time, though levels vary by plant variety and gene.

Both conventionally and organically fertilized tomatoes maintain fruit quality through uncontrolled green peach aphid infestation, with a transcriptional shift towards catabolism

This study examines how conventional and organic tomato plants respond to aphid infestation, finding no significant yield loss and a transcriptional shift towards catabolism in leaves.
