Viburnum lesquereuxii leaf with insect damage; Dakota Sandstone (Cretaceous) of Ellsworth County, Kansas. Scale bar is 10 mm. Knowledge of herbivory in geological time comes from three sources: fossilized plants, which may preserve evidence of defense (such as spines) or herbivory-related damage; the observation of plant debris in fossilised animal feces; and the structure of herbivore mouthparts.
G. nivalis also produces an active agglutinin protein known as GNA, which due to its insecticidal properties has been introduced into some varieties of genetically modified potatoes to protect them from insect pests. A controversial experiment conducted in the 1990s reported gastrointestinal and immune system damage in rats fed these potatoes ...
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
An important enzyme produced by herbivorous insects is protease. The protease enzyme is a protein in the gut that helps the insect digest its main source of food: plant tissue. Many types of plants produce protease inhibitors, which inactivate proteases. Protease inactivation can lead to many issues such as reduced feeding, prolonged larval ...
The fruit or "apple" is usually produced early in summer and ripens later in summer. Many species of plants have mycorrhizae to assist with nutrient uptake in infertile conditions. Mayapple plants are considered obligately dependent upon such mycorrhizae, although it may also be facultatively dependent upon rhizome age and soil nutrient levels ...
