Insect Odorscapes: From Plant Volatiles to Natural Olfactory Scenes

Frontiers in Physiology, 2019
Olfaction is an essential sensory modality for insects and their olfactory environment is mostly made up of plant-emitted volatiles. The terrestrial vegetation produces an amazing diversity of volatile compounds, which are then transported, mixed, and ...

Physiological adaptations to sugar‐mimic alkaloids: Insights from Bombyx mori for long‐term adaption and short‐term response

Ecology and Evolution, 2020
Insects evolved adaptive plasticity to minimize the effects of the chemical defenses of their host plants. Nevertheless, the expressional response and adaptation of phytophagous specialists for long‐term adaption and short‐term response to host ...

Common resistance mechanisms are deployed by plants against sap-feeding herbivorous insects: insights from a meta-analysis and systematic review

Scientific Reports, 2022
Despite their abundance and economic importance, the mechanism of plant resistance to sap-feeding insects remains poorly understood. Here we deploy meta-analysis and data synthesis methods to evaluate the results from electrophysiological studies ...

Plant-litter-soil feedbacks in common grass species are slightly negative and only marginally modified by litter exposed to insect herbivory [PDF]

, 2022
Purpose Insect herbivory affects plant growth, nutrient and secondary metabolite concentrations and litter quality. Changes to litter quality due to insect herbivory can alter decomposition, with knock on effects for plant growth mediated through the ...

The Use of Engineered Plant Viruses in a Trans-Kingdom Silencing Strategy Against Their Insect Vectors

Frontiers in Plant Science, 2020
Plants, plant viruses, and their vectors are co-evolving actors that co-exist and interact in nature. Insects are the most important vectors of plant viruses, serving as both carriers and hosts for the virus.

Plant–Insect Interactions in a Changing World

, 2017
Abstract Global change is resetting the spatial and ecological equilibrium of complex co-evolutionary relationships between plants and their insect herbivores. We review the mechanisms at play in the responses of plant–insect interactions to global changes, including increased temperature and atmospheric CO2 concentrations, modification of land use ...

Research advances in plant–insect molecular interaction [PDF]

F1000Research, 2020
Acute and precise signal perception and transduction are essential for plant defense against insects. Insect elicitors—that is, the biologically active molecules from insects’ oral secretion (which contains regurgitant and saliva), frass, ovipositional fluids, and the endosymbionts—are recognized by plants and subsequently induce a local or systematic ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Metabolic analysis of the interaction between plants and herbivores

, 2008
Insect herbivores by necessity have to deal with a large arsenal of plant defence metabolites. The levels of defence compounds may be increased by insect damage.
