PTI and ETI: convergent pathways with diverse elicitors
WEBPlants rely on PAMP-triggered immunity (PTI) and effector-triggered immunity (ETI) to detect invading pathogens and subsequently activate defense mechanisms.
PTI and ETI: convergent pathways with diverse elicitors
WEBFeb 1, 2022 · ETI potentiates PTI by increasing the expression of key PTI signaling components, including BIK1, BAK1, MAPK3, and RBOHD. PTI induced by flg22 or nlp20 significantly upregulates the expression of TNL genes.
PTI-ETI crosstalk: an integrative view of plant immunity
WEBAlthough the two classes of immune receptors involve different activation mechanisms and appear to require different early signalling components, PTI and ETI eventually converge into many similar downstream responses, albeit with distinct amplitudes and dynamics.
PTI-ETI crosstalk: an integrative view of plant immunity
WEBAug 1, 2021 · Although the two classes of immune receptors involve different activation mechanisms and appear to require different early signalling components, PTI and ETI eventually converge into many similar downstream responses, albeit with distinct amplitudes and dynamics.
PTI-ETI synergistic signal mechanisms in plant immunity
WEBMar 12, 2024 · PICI1 mediates immunity through the synthesis of the ethylene (ET), a plant hormone that is recognized, targeted and degraded by fungal effectors. The NLR PigmR protects PICI1 from degradation, synchronizes ETI with PTI and ensures disease resistance (Zhai et al., 2022). Prior studies have established that PTI is essential for effective ETI.
Mutual potentiation of plant immunity by cell-surface and ... - Nature
WEBMar 10, 2021 · We tested (i) whether PTI provides the main defence mechanism against pathogens; and (ii) whether ETI enhances PTI by replenishing PTI components, thus restoring effector-attenuated PTI.
Plant immunity unified - Nature Plants
WEBMar 30, 2021 · PTI generally confers low-level, basal immunity, which is effective against non-adapted pathogens, whereas ETI confers more robust immunity to host-adapted pathogens. Until recently, ETI...
PTI and ETI are one - Nature Plants
WEBDec 14, 2021 · Pattern-triggered immunity (PTI) is induced when membrane receptors perceive generic molecules from microorganisms; it provides basal immunity against entire classes of pathogens.
WEBPTI and ETI potentiate each other to induce stronger defense responses. ETI potentiates PTI by increasing the expression of key PTI signaling components, including BIK1, BAK1, MAPK3, and RBOHD. PTI induced by flg22 or nlp20 significantly upregulates the expression of TNL genes.
Recent Advances in Effector-Triggered Immunity in Plants: …
WEBApr 29, 2021 · The synergistic cooperation of PTI and ETI provides a robust immunity to confront pathogenic invasion. In particular, PTI combats pathogenic microbes by reinforcing cell walls, increasing callose deposition, and producing anti-microbial compounds. Meanwhile, ETI sharpens PTI function by upregulating the PTI components.
