Experimental Growth Conditions affect Direct and Indirect Defences in two Cotton Species
Cotton has been used as a model plant to study direct and indirect plant defence against herbivorous insects. However, the plant growing conditions...

Ecogeographical determinants of investment in chemical defences in pines
Key messagePine tree species exhibit significant levels of phenotypic variation in the investment in defences, which can be correlated with...

Do omnivorous black bullhead (Ameiurus melas) and planktivorous common bleak (Alburnus alburnus) elicit different inducible defences in Daphnia magna?
The aim of this study was to explore whether the widespread zooplankter Daphnia magna is able to differentiate between the kairomones of...

Silicon fertilisation affects morphological and immune defences of an insect pest and enhances plant compensatory growth
Herbivorous insects have evolved various anti-predator defences, including morphological, behavioural, and immune defences, which can make biocontrol...

Hormetic response and co-expression of cytochrome P450 and cuticular protein reveal the tolerance to host-specific terpenoid defences in an emerging insect pest, Pagiophloeus tsushimanus (Coleoptera: Curculionidae)
Camphor oil (EO) and its main component (i.e. d -camphor) form specific terpenoid defences in camphor trees, Cinnamomum camphora . However, an emerging...

Simulated Herbivory Affects the Volatile Emissions of Oak Saplings, while Neighbourhood Affects Flavan-3-ols Content of Their Leaves
To what extent particular plant defences against herbivorous insects are constitutive or inducible will depend on the costs and benefits in their...

Effects of individual traits vs. trait syndromes on assemblages of various herbivore guilds associated with central European Salix
Plants employ diverse anti-herbivore defences that can covary to form syndromes consisting of multiple traits. Such syndromes are hypothesized to...

Branch-Localized Induction Promotes Efficacy of Volatile Defences and Herbivore Predation in Trees
Induction of plant defences can show various levels of localization, which can optimize their efficiency. Locally induced responses may be...

The genome of homosporous maidenhair fern sheds light on the euphyllophyte evolution and defences
Euphyllophytes encompass almost all extant plants, including two sister clades, ferns and seed plants. Decoding genomes of ferns is the key to deep...

Can Aphid Herbivory Induce Intergenerational Effects of Endophyte-conferred Resistance in Grasses?
Plants have evolved mechanisms to survive herbivory. One such mechanism is the induction of defences upon attack that can operate...
-
Rising temperatures favour defence-suppressing herbivores
Rising temperatures due to climate change are predicted to accelerate the life cycle of arthropod herbivores thereby exacerbating pest formation....

Phage–host coevolution in natural populations
Coevolution between bacteriophages (phages) and their bacterial hosts occurs through changes in resistance and counter-resistance mechanisms. To...

Responses to larval herbivory in the phenylpropanoid pathway of Ulmus minor are boosted by prior insect egg deposition
Main conclusionElms, which have received insect eggs as a ‘warning’ of larval herbivory, enhance their anti-herbivore defences by accumulating...

Innate immune evasion strategies of SARS-CoV-2
SARS-CoV-2, the virus responsible for the COVID-19 pandemic, has been associated with substantial global morbidity and mortality. Despite a tropism...

Transcriptional and metabolite analysis reveal a shift in direct and indirect defences in response to spider-mite infestation in cucumber (Cucumis sativus)
Key messageCucumber plants adapt their transcriptome and metabolome as result of spider mite infestation with opposite consequences for direct and...

PSKR1 balances the plant growth–defence trade-off in the rhizosphere microbiome
Microbiota benefit their hosts by improving nutrient uptake and pathogen protection. How host immunity restricts microbiota while avoiding...

Alteration in the developmental physiology of Maruca vitrata (Fabricius) on jasmonic acid and salicylic acid treated pigeonpea
Spotted pod borer, Maruca vitrata (F.), is one of the severe threats to grain legumes in the tropics and subtropics owing to its destructiveness and...
-
Silicon suppresses a ubiquitous mite herbivore and promotes natural enemy attraction by altering plant volatile blends
Silicon (Si) accumulation in plants is widely recognised as an effective physical defence against chewing herbivores. However, its effects on some...

Eucalyptol Protects against Cisplatin-Induced Liver Injury in Rats
AbstractEucalyptol (1,8-cineole), a terpenoid oxide, is known as the main component of eucalyptus essential oils. The antimicrobial,...

Predator-induced defence in a dinoflagellate generates benefits without direct costs
Inducible defences in phytoplankton are often assumed to come at a cost to the organism, but trade-offs have proven hard to establish experimentally....
