Ustilago maydis is a pathogenic plant fungus that causes smut disease in maize and teosinte. Plants have evolved efficient defense systems against pathogenic microbes such as U. maydis. A rapid defense reaction after pathogen attack is the oxidative burst where the plant produces reactive oxygen species at the site of the attempted invasion. U. maydis can respond to the oxidative burst with an oxidative stress response, regulated by the gene YAP1.

Plants have evolved efficient defense systems against pathogenic microbes. A rapid plant defense reaction after pathogen attack is the oxidative burst, which involves the production of reactive oxygen species at the site of the attempted invasion. As a pathogen, U. maydis can respond to such an oxidative burst by an oxidative stress response, regulated by gene YAP1. This response protects U. maydis from the host attack, and is necessary for the pathogen’s virulence.

This impairment can cause different species to lack the sensation of fear, and often can become overly confident, confronting larger peers, or walking up to predatory creatures. Robert C. Bolles (1970), a researcher at University of Washington, wanted to understand species-specific defense reactions and avoidance learning among animals, but found that the theories of avoidance learning and the tools that were used to measure this tendency were out of touch with the natural world. He theorized the species-specific defense reaction (SSDR). There are three forms of SSDRs: flight, fight (pseudo-aggression), or freeze.

The operation prompted a frantic air defense reaction at 02:17 that provided a highly effective diversion for the raiders and completely saturated the North Vietnamese air defense system. Both Air Force formations,Gargus (2007), p. 71. over a period of thirteen minutes, were unavoidably but separately exposed for several minutes each to an early warning radar located at Na San, North Vietnam, to the north, because the flight tracks had to be routed around uncharted mountains. Neither formation was detected, possibly because of the diversion.Gargus (2007), p. 160.

The ratio of recovered individuals is skewed towards males, indicating fewer females or spatial segregation by sex. Its primary defense reaction is to freeze in place, then if needed, the secondary defense involves pushing away from the bottom then drifting back down. V. hydrothermalis uses its front arms (I dorsal and II dorsolateral) for feeling its way around and detecting and catching prey, while the back arms (III ventrolateral and IV ventral) support its weight and move the octopus forward. This species has not been observed to use jet propulsion.

A study by Reis and Gunne (1965) found that electrically stimulating the amygdala of cats caused sham rage, which resulted in a decrease in the presence of adrenaline and noradrenaline. They believed this was because the excited defense reaction known as sham rage caused such a huge increase in the release of the neurotransmitters that the brain could not resynthesize noradrenaline fast enough to keep up. Reis and Fuxe (1969) then did a study of cats that went into a sham rage after having a brainstem transection. The purpose was to determine the relationship between the decrease in norepinephrine in sham rage and the magnitude of the sham rage behavior.
