Pattern Recognition Receptors (PRRs) are a crucial part of the immune system in plants and animals.
They are specialized proteins that play a fundamental role in detecting various molecular patterns associated with pathogens (such as bacteria, viruses, and fungi) or damage in the environment.
PRRs are present on the surface of cells or within cells and help the immune system recognize "pathogen-associated molecular patterns" (PAMPs) that are unique to microorganisms.
When PRRs recognize PAMPs, they trigger a series of immune responses to defend against the invading pathogens or respond to environmental stress.
In plants, PRRs help initiate the defense responses against potential threats like infections, pests, and diseases.
Activation of PRRs leads to the activation of immune signaling pathways and the production of defense molecules to prevent or limit the spread of pathogens.
Why in News
A genetic screening was conducted on wild potatoes and other Solanum species.
The screening identified a new plant cell surface pattern recognition receptor (PRR) named PERU.
PERU plays a role in the immune response to Phytophthora infestans, a pathogen responsible for the Great Irish Famine in the 1840s.
This discovery has the potential to enhance crop resilience and improve plant immunity.
Pattern recognition receptors (PRRs) and intracellular immune receptors work together to grant plants immunity against microbial infections.
