A holistic view on plant effector-triggered immunity
Apr 10, 2020 · The immune system of plants is highly complex. It involves pattern-triggered immunity (PTI), which is signaled and manifested through branched multi-step pathways. To counteract this, pathogen effectors target and inhibit individual PTI steps. This in turn can cause specific plant cytosolic nucleotide-binding leucine-rich repeat (NLR) receptors to activate effector-triggered immunity (ETI
Effector-Triggered Immunity: From Pathogen Perception to
In plant innate immunity, individual cells have the capacity to sense and respond to pathogen attack. Intracellular recognition mechanisms have evolved to intercept perturbations by pathogen virulence factors (effectors) early in host infection and convert it to rapid defense. One key to resistance success is a polymorphic family of intracellular nucleotide-binding/leucine-rich-repeat (NLR) receptors that detect effector interference in different parts of the cell.
Effector-triggered immunity - Wikipedia
Effector-triggered immunity. The host cell detects the presence of the pathogen directly from the molecular patterns on the pathogen and indirectly through the damage caused to the host cell by the toxins generated by the pathogen. Effector-triggered immunity ( ETI) is one of the pathways, along with the Pattern-Triggered Immunity (PTI) pathway, by which the innate immune system recognises pathogenic organisms and elicits a protective immune response.
A plant effector‐triggered immunity signaling sector is
Aug 15, 2017 · Two modes of plant immunity are well defined: pattern-triggered immunity (PTI) and effector-triggered immunity (ETI; Jones & Dangl, 2006; Dodds & Rathjen, 2010). PTI is triggered by recognition of molecular cues that are conserved among related microbes (MAMPs) by cognate pattern-recognition receptors (PRR) on the plant cell membrane.
