Systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen.SAR is analogous to the innate immune system found in animals, and although there are many shared aspects between the two systems, it is thought to be a result of convergent evolution. [1]
Plant disease resistance protects plants from pathogens in two ways: by pre-formed structures and chemicals, and by infection-induced responses of the immune system.
The motor system acts to point both eyes at the target of interest; any offset is detected visually (and the motor system corrects it). Heterophoria occurs only during dissociation of the left eye and right eye, when fusion of the eyes is absent.
The history of plant systematics—the biological classification of plants—stretches from the work of ancient Greek to modern evolutionary biologists. As a field of science, plant systematics came into being only slowly, early plant lore usually being treated as part of the study of medicine.
A process plant shutdown system is a functional safety countermeasure crucial in any hazardous process plant such as oil and gas production plants and oil refineries. The concept also applies to non-process facilities such as nuclear plants. These systems are used to protect people, assets, and the environment when process conditions get out of ...
Sandow Power Plant was a 1.1-gigawatt (1,137 MW) coal power plant located southwest of Rockdale, Texas in Milam County, Texas. It was operated by Luminant , a subsidiary of Vistra Corp . The plant closed in 2018.
Plant as used in Chinese herbology (crude medicine) Remains of a buried Neanderthal found at Shanidar cave in Iraqi Kurdistan, over 50,000 years old was found associated with Ephedra pollen among those of other plants. While some authors have suggested that these represent plant remains deliberately buried alongside the Neanderthal, other ...
