HYPERSENSITIVE RESPONSE Meaning and
Definition
-
Hypersensitive response refers to a rapid and heightened reaction displayed by plants when they are exposed to certain infectious agents, particularly pathogens. It is a form of localized defense mechanism that is activated by the plant's immune system in order to counteract the invasion of harmful pathogens such as bacteria, viruses, or fungi.
The hypersensitive response is characterized by a series of biochemical and physiological reactions that occur in the infected plant tissue. One of the prominent features of this response is the rapid death of cells surrounding the site of infection, known as the hypersensitive cell death. This programmed cell death is an important defense strategy to prevent the spread of pathogens by isolating and killing the infected cells.
The hypersensitive response also involves the production of various chemical compounds, such as antimicrobial proteins, reactive oxygen species, and signaling molecules, which collectively help in enhancing the plant's resistance against the invading pathogens. These chemical defenses act by inhibiting the growth and spread of pathogens or by attracting other beneficial organisms that can aid in pathogen control.
Overall, the hypersensitive response serves as a crucial mechanism for plants to recognize and combat pathogenic invasion. By swiftly activating defense mechanisms at the site of infection, plants can effectively limit the damage caused by pathogens and enhance their chances of survival.

Etymology of HYPERSENSITIVE RESPONSE
The etymology of the word "hypersensitive response" can be broken down as follows:
"Hypersensitive" is a combination of two words: "hyper" and "sensitive".
- "Hyper" is derived from the Greek prefix "hyper-" meaning "over" or "excessive".
- "Sensitive" is derived from the Latin word "sensibilis", which means "capable of feeling".
"Response" is derived from the Latin word "respondere", meaning "to answer" or "to reply".
Therefore, the term "hypersensitive response" refers to an exaggerated or excessive reaction or reply to a stimulus or trigger.
