Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...
The plant is toxic enough to cause human and animal fatalities if ingested. Every part of the plant is poisonous, especially the tuberous rhizomes. As with other members of the Colchicaceae, this plant contains high levels of colchicine, a toxic alkaloid. It also contains the alkaloid gloriocine.
Herbicidal warfare is the use of substances primarily designed to destroy the plant-based ecosystem of an area. Although herbicidal warfare use chemical substances, its main purpose is to disrupt agricultural food production and/or to destroy plants which provide cover or concealment to the enemy, not to asphyxiate or poison humans and/or destroy human-made structures.
Toxins: These can be non-host-specific, which damage all plants, or host-specific, which cause damage only on a host plant. Effector proteins: These can be secreted by pathogens such as bacteria, fungi, and oomycetes [6] [7] into the extracellular environment or directly into the host cell, often via the Type three secretion system. Some ...

Recently, incidences of non-target site resistance have increasingly emerged, such as examples where plants are capable of producing enzymes that neutralize herbicides before they can enter the plant's cells – metabolic resistance. This form of resistance is particularly challenging, since plants can develop non-target-site resistance to ...
Another way that plants alter their morphology to protect against stress is by changing the leaf orientation. [2] Plants can suffer from heat stress if the sun’s rays are too strong. Changing the orientation of their leaves in different directions (parallel or perpendicular) allows plants to reduce damage from intense light.
