Interactions between effector-triggered immunity (ETI) and pattern-triggered immunity (PTI) in an Arabidopsis dde2 ein2 pad4 sid2 mutant

Project description:We observed inhibition of the hypersensitive response (a typical ETI response) by PTI signaling in an Arabidopsis quadruple mutant dde2 ein2 pad4 sid2 (quad). Thus, we designed an experiment to see the interaction between ETI and PTI signaling at the transcriptome level. The Arabidopsis line dde2 ein2 pad4 sid2 Ed-AvrRpt2 (quadAvrRpt2) was used (Ed-AvrRpt2, estradiol-inducible AvrRpt2 transgene). In this plant line, ETI can be elicited by estradiol (Ed) treatment via in planta expression of AvrRpt2. Transcriptome responses to PTI only, ETI only, and PTI+ETI together were recorded.

Transcriptome analysis of TPR1/TPL mutant lines during Pst AvrRps4- triggered immunity

Project description:Plant Topless (TPL) and Topless-related (TPR) corepressors are important regulators of plant hormone and immunity signaling. We present here the transcriptome of tpr1 and tpr1 tpl tpr4 triple mutant lines (t3) during TNL-triggered immunity in Arabidopsis thaliana after infection with Pst avrRps4 (OD 0.005). Col-0 and eds1-2 were analysed as controls.

Expression analysis of Arabidopsis transgenic plants carrying DEX-inducible MKK4DD in Col or sid2 background treated with DEX or control

Project description:Effector-Triggered Immunity (ETI) and Pattern-Triggered Immunity (PTI) are well-defined modes of plant immunity triggered by recognition of pathogen effector proteins and microbe-associated molecular patterns, respectively. While ETI and PTI network extensively share signaling components, the shared components are used in different ways, resulting in distinct network properties in the model plant Arabidopsis: immunity is highly robust against network perturbations in ETI but relatively sensitive in PTI. However, the molecular mechanism how the shared network leads to the different properties is not known. Here we show that sustained MAPK activation compensate salicylic acid (SA) signaling. A 12 DNA microarray study using total RNA from Arabidopsis transgenic plants carrying DEX-inducible MKK4DD in Col or sid2-2 background treated with DEX or control.

An immune-inducible trihelix transcription factor suppresses bacterial resistance in Arabidopsis thaliana

Project description:The plant innate immunity consists of the two interconnected mechanisms, pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). Although much is known about how plants trigger immune responses upon pathogen recognition, the genetic program by which plants avoid an overshoot in pathogen-triggered immune responses remains largely unknown. Here, we discovered a trihelix transcription factor, GT-3a, as an immune-inducible negative regulator of bacterial resistance in Arabidopsis thaliana. Analysis of public RNA-seq data revealed that GT-3a is specifically induced by ETI activation not by PTI activation. Overexpression of GT-3a suppressed resistance against the bacterial pathogen Pseudomonas syringae pv. tomato DC3000 (Pto) and Pto-elicited expression of salicylic acid (SA)-responsive genes. Our results suggest that transcriptional induction of GT-3a circumvents the overshooting of SA-mediated defense responses during ETI.

Two unequally redundant 'helper' immune receptor families mediate Arabidopsis intracellular 'sensor' immune receptor functions

Project description:Investigate the function of RNLs in transcriptional reprogramming during Pf0-1-induced PTI and ETI, using time-resolved transcriptomics. To do so we subjected Col-0, adr1 triple, nrg1.1 nrg1.2 and helperless mutants to infections with Pf0-EV (RNL-(in)dependent PTI), Pf0-AvrRps4 (fully RNL-dependent ETI + PTI), Pf0-AvrRpt2 (partial RNL-dependent ETI + PTI) or Pf0-AvrRpm1 (RNL-independent ETI + PTI).
