Foliar Morphoanatomical and Phytochemical Variations Shape Resistance to Key Insect Herbivores and Leaf Quality in Cyclocarya paliurus

Plants
To reveal the effects of genotype–herbivore interactions on leaf quality, foliar variations in phytochemicals, morphoanatomy, and herbivory damage ratio were investigated in a Cyclocarya paliurus (Batalin) Iljinsk. (Juglandaceae) germplasm resources bank.

Interacting effects of insect and ungulate herbivory on Scots pine growth

Scientific Reports, 2020
Most plants are subjected to damage from multiple species of herbivores, and the combined impact on plant growth can be non-additive. Since plant response to herbivores tends to be species specific, and change with repeated damage, the outcome likely ...

Impact of non-outbreak insect damage on vegetation in northern Europe will be greater than expected during a changing climate [PDF]

, 2018
Background insect herbivory, in addition to insect outbreaks, can have an important long term influence on the performance of tree species. Since a projected warmer climate may favour insect herbivores, we use a dynamic ecosystem model to investigate the

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

Pest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.

Interspecific differences in the larval performance of Pieris butterflies (Lepidoptera: Pieridae) are associated with differences in the glucosinolate profiles of host plants

, 2019
The tremendous diversity of plants and herbivores has arisen from a coevolutionary relationship characterized by plant defense and herbivore counter adaptation. Pierid butterfly species feed on Brassicales plants that produce glucosinolates as a chemical

Effects of elevated [CO2 ] on maize defence against mycotoxigenic Fusarium verticillioides. [PDF]

, 2014
Maize is by quantity the most important C4 cereal crop; however, future climate changes are expected to increase maize susceptibility to mycotoxigenic fungal pathogens and reduce productivity. While rising atmospheric [CO2 ] is a driving force behind the

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

An unbiased approach elucidates variation in (S)-(+)-linalool, a context-specific mediator of a tri-trophic interaction in wild tobacco

, 2019
Plant volatile organic compounds (VOCs) mediate many interactions, and the function of common VOCs is especially likely to depend on ecological context.

Preface: Impacts of extreme climate events and disturbances on carbon dynamics [PDF]

, 2016
The impacts of extreme climate events and disturbances (ECE&D) on the carbon cycle have received growing attention in recent years. This special issue showcases a collection of recent advances in understanding the impacts of ECE&D on carbon cycling ...
