Plants have developed a highly developed immune system to fend off pathogens and pests. Higher plants have a huge number of immunological receptors on their cell surfaces and within their cells, allowing them to detect a variety of immunogenic signals related to pathogen infections. Microbe-associated molecular patterns are immunogenic microbial patterns that are mostly consistent across taxonomic groupings (MAMPs). Additionally, infections can harm plant tissues by secreting enzymes that break down plant cell walls and release plant cell wall fragments, extracellular ATP, and nicotinamide adenine dinucleotide (NAD). These molecules, which are produced from plants, can act as immune responses' damage-associated molecular patterns (DAMPs). These MAMPs and DAMPs are recognized by surface-localized pattern-recognition receptors (PRRs) and activate pattern-triggered immunity (PTI). Additionally, the nucleotide binding leucine-rich repeats (NB-LRR) proteins recognise pathogenic proteins in the cytoplasm and trigger the second line of plant defence, the Effector-Triggered Immunity (ETI). In addition to managing pre-programmed defence responses, plants have the ability to improve their immune system's reactivity in response to certain environmental cues. This phenomenon is known as "defence priming.". Because it minimizes unnecessary metabolic use in plants, priming is one of the most cost-efficient and effective forms of resistance
