Any process by which callose is transported to, and/or maintained in, a specific location during the defense response. Callose is a linear 1,3-beta-d-glucan formed from UDP-glucose and is found in certain plant cell walls. Reactions triggered in response to the presence of a tumor cell that act to protect the cell or organism. Reactions triggered in response to the presence of a fungus that act to protect the cell or organism. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis, usually, but not necessarily, exogenous (e.g. temperature, humidity, ionizing radiation). Reactions triggered in response to the presence of a protozoan that act to protect the cell or organism. Reactions triggered in response to the presence of oomycetes that act to protect the cell or organism. Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack. A response to protect an organism from a directly detected or perceived external threat from a nematode or nematodes, which results in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack. A type of cell wall modification, in which the cell wall is reinforced and made thicker, that occurs as part of the defense response of an organism. Any process, either active or passive, by which an organism avoids or tolerates the effects of a second organism's defense response; the defense response is mounted by the second organism in response to the presence of the first organism, where the two organisms are in a symbiotic interaction. A response to protect an organism from a directly detected or perceived external threat from an insect or insects to that organism. A phase of elevated metabolic activity, during which oxygen consumption increases made as part of a defense response ; this leads to the production, by an NADH dependent system, of hydrogen peroxide (H2O2), superoxide anions and hydroxyl radicals. A behavioral response seeking to protect an organism from an a perceived external threat to that organism. A defense response that is mediated by cells. Reactions triggered in response to the presence of a virus that act to protect the cell or organism. The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages. Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. Any process that stops, prevents or reduces the frequency, rate or extent of a defense response. Reactions triggered in response to the presence of a parasitic plant that act to protect an organism. Any process that modulates the frequency, rate or extent of a defense response. Any process that activates or increases the frequency, rate or extent of a defense response. Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus.
