Systemic Acquired Resistance (SAR)
SAR is a plant defense mechanism that is induced after a plant has been exposed to a pathogen attack. This phenomenon allows the plant to build up resistance to future pathogen attacks.
Mechanism of SAR
- When a plant is infected by a pathogen, it activates a signaling pathway that triggers the production of signaling molecules such as salicylic acid.
- These signaling molecules travel throughout the plant, alerting other parts of the plant to prepare for potential future attacks.
- This priming effect allows the plant to respond more rapidly and effectively to subsequent pathogen attacks.
Benefits of SAR
- SAR provides long-lasting protection to the plant, making it more resilient to various pathogens.
- It is a cost-effective defense mechanism for plants, as it does not require constant activation like other defense mechanisms.
Difference from Other Defense Mechanisms
- SAR is different from the hypersensitive response, which is a rapid cell death at the site of infection to prevent the spread of pathogens.
- SAR is also distinct from innate immunity, which is a general defense mechanism present in all plants.
In conclusion, SAR is an important defense mechanism in plants that allows them to adapt and build resistance to future pathogen attacks. Through the activation of signaling pathways and the production of signaling molecules, plants are able to enhance their defense mechanisms and improve their overall resilience.
