Carbon starvation by light deprivation does not constrain the ability of young pines to produce induced chemical defences in response to a bark-chewing herbivore

Environmental and Experimental Botany, 2016
Pine tree chemical defence is based on constitutive and inducible carbon-rich substances (mainly oleoresin and phenolic compounds) present in pine tissues in conspicuously high concentrations.

A chemical defence against phage infection

Nature, 2018
The arms race between bacteria and the phages that infect them drives the continual evolution of diverse anti-phage defences. Previously described anti-phage systems have highly varied defence mechanisms1-11; however, all mechanisms rely on protein components to mediate defence.

Fruit defence syndromes: the independent evolution of mechanical and chemical defences

Evolutionary Ecology, 2017
Plants are prone to attack by a great diversity of antagonists against which they deploy various defence mechanisms, of which the two principle ones are mechanical and chemical defences. These defences are hypothesized to be negatively correlated due to either functional redundancy or a trade-off, i.e., plants which rely on increased mechanical defence

Chemical Defences in Aquatic Plants

The Journal of Ecology, 1986
(1) Fifteen species of aquatic vascular plants were examined for the presence of alkaloids. (2) The alkaloid content ranged from 0.13 mg g-1 dry weight in Heteranthera dubia to 0.56 mg g-1 dry weight in Potamogeton crispus. These concentrations are within a range which has been found to be pharmacologically active in previous studies, and can therefore

THE BODY'S CHEMICAL MECHANISMS OF DEFENCE*

Nature, 1947
THE defence of the body against the poisonous action of compounds of simple chemical constitution is effected by a variety of chemical reactions. The toxic compound may be oxidized to a non-poisonous product, or to one for which a rapid means of elimination exists.

Chemical Defence of a Centipede (Clinopodes Flavidus)

Journal of Insect Physiology
Chemical substances are of utmost importance for the biotic interactions between animals and their predators/parasites; many of these semiochemicals are emitted for defence purposes. One of the most deterrent and toxic biogenic substances we know of is hydrogen cyanide, which can be stored by certain insects, millipedes, centipedes and arachnids in the
