DNA damage accumulation as a result appears to become a frequent function of autoimmune MFZ 10-7 In Vivo mutants with accelerated cell death which includes pub13, vad1 and camta3. Our data also suggest that constitutive accumulation of SA is insufficient to lead to DNA harm considering the fact that dnd1 mutants have no indicators of improved DNA harm. This conclusion is based on the observation that each of the mutants tested accumulate SA but only camta3, vad1 and pub13 have macroscopic cell death lesions [248] and DNA harm. In contrast to a prior report [17], Song and Bent [21], could not detect drastically increased DNA damage in WT plants treated with SA, and we Benzophenone web verified this with SA and its analogs BTH and INA (Fig 3AD).PLOS Genetics | https://doi.org/10.1371/journal.pgen.1007235 February 20,four /DNA damage symptomatic of diseaseFig two. DNA damage accumulation inside the camta three mutant is dependent on NLR signalling. Accumulation of DNA harm in camta three is dependent around the NLR signalling element EDS1 and around the NLR DSC2.

Since the camta3-1 phenotype is dependent on EDS1 and DSC2, we tested if detection of a single effector could be enough to induce accumulation of DNA damage. Song and Bent [21] showed that P. fluorescens, a bacterium identified to induce systemic resistance in plants, doesn’t bring about DNA harm accumulation when infiltrated into Arabidopsis. We hence infected rpm1-3, a loss-of-function mutant with the RPM1 NLR which detects AvrRPM1, and wild kind Col-0 with P. fluorescens expressing the effector AvrRPM1. As anticipated, although Col-0 triggers ETI and accumulates DNA damage upon recognition ofPLOS Genetics | https://doi.org/10.1371/journal.pgen.1007235 February 20,5 /DNA harm symptomatic of diseaseFig 3. SA analogues BTH and INA do not induce important accumulation of DNA damage.
