systemic acquired resistance , SAR (skrót)

It has an important role in response to wounding of plants and systemic acquired resistance.

They are induced as part of systemic acquired resistance.

Other treatment include the use of chemicals that trigger systemic acquired resistance or improve stress tolerance.

The two proteins induced a hypersensitive response and systemic acquired resistance within the banana plant after being exposed to the bacterial pathogen.

Lower levels of reactive oxygen species initiate systemic acquired resistance, triggering defense-molecule production in the rest of the plant.

Methyl jasmonate is volatile and can therefore activate systemic acquired resistance in neighbouring plants, preparing their defences for attack.

Induction of Systemic Acquired Resistance to Puccinia sorghi in Corn.

Systemic acquired resistance (SAR) is a type of defensive response used by plants that renders the entire plant resistant to a particular infectious agent.

Leaf necrosis provides immediate control of fungal invasion and induces systemic acquired resistance; both responses mediate basic protection against subsequent pathogen inoculation.

The systemic acquired resistance (SAR) is a "whole-plant" resistance response that occurs following an earlier localized exposure to a pathogen.

This view was challenged by grafting experiments which showed that mutants deficient in jasmonic acid biosynthesis and perception were unable to activate systemic acquired resistance.

It is involved in the systemic acquired resistance (SAR) in which a pathogenic attack on one part of the plant induces resistance in other parts.

Systemic acquired resistance (SAR) is another example of resistance which is better understood in plants because of research done in A. thaliana.

Microbial inoculants can induce systemic acquired resistance (SAR) of crop species to several common crop diseases (provides resistance against pathogens).

In addition, a local alkalinization of the apoplast due to such a stress can travel within minutes to the rest of the plant body via the xylem and trigger systemic acquired resistance.

Background In response to local infection with necrotizing pathogen, plants display a whole plant enhanced immunity to secondary challenge (systemic acquired resistance or SAR) [ 1 ] .

These responses include systemic acquired resistance, largely mediated by salicylic acid-dependent pathways, and induced systemic resistance, largely mediated by jasmonic acid-dependent pathways.

The HR is analogous to the innate immune system found in animals, and commonly precedes a slower systemic (whole plant) response, which ultimately leads to systemic acquired resistance (SAR).

The concentration of hydrogen peroxide increased in the vasculature tissues when the production of systemin, HypSys or AtPep1 is induced, this may also be involved in initiating systemic acquired resistance.

Systemic acquired resistance experiments SAR experiments were performed as previously described [ 4 ] except that hand inoculation using a syringe was used instead of vacuum infiltration to introduce the challenge pathogen.

Early experiments showed that systemin travelled around the plant after insects had damaged the plant, activating systemic acquired resistance, now it is thought that it increases the production of jasmonic acid causing the same result.

Early experiments with radiolabelled systemin in tomato demonstrated that it is transported through the phloem sap in tomato plants and was therefore thought to be the systemic signal that activated systemic acquired resistance.

The transcription responses from these factors usually induce a primary gene response, which triggers a secondary gene response, and finally the cross-talk interaction of the two causes a systemic acquired resistance (SAR) in the plant.

SA, a hormone, mediates defense against pathogens by inducing both the expression of pathogenesis-related genes and systemic acquired resistance (SAR), in which the whole plant gains resistance to a pathogen after localized exposure to it.

Long-term resistance, or systemic acquired resistance (SAR), involves communication of the damaged tissue with the rest of the plant using plant hormones such as jasmonic acid, ethylene, abscisic acid or salicylic acid.
