Abstract

Summary: Most land plant genomes carry genes that encode RPW 8‐NLR Resistance (R) proteins. Angiosperms carry two RPW 8‐NLR subclasses: ADR 1 and NRG 1. ADR 1s act as ‘helper’ NLR s for multiple TIR‐ and CC‐NLR R proteins in Arabidopsis. In angiosperm families, NRG 1 co‐occurs with TIR‐NLR Resistance (R) genes. We tested whether NRG 1 is required for signalling of multiple TIR‐NLR s. Using CRISPR mutagenesis, we obtained an nrg1a‐nrg1b double mutant in two Arabidopsis accessions, and an nrg1 mutant in Nicotiana benthamiana. These mutants are compromised in signalling of all TIR‐NLR s tested, including WRR 4A, WRR 4B, RPP 1, RPP 2, RPP 4 and the pairs RRS 1/RPS 4, RRS 1B/RPS 4B, CHS 1/SOC 3 and CHS 3/CSA 1. In Arabidopsis, NRG 1 is required for the hypersensitive cell death response (HR) and full oomycete resistance, but not for salicylic acid induction or bacterial resistance. By contrast, nrg1 loss of function does not compromise the CC‐NLR R proteins RPS 5 and MLA. RPM 1 and RPS 2 (CC‐NLR s) function is slightly compromised in an nrg1 mutant. Thus, NRG 1 is required for full TIR‐NLR function and contributes to the signalling of some CC‐NLR s. Some NRG 1‐dependent R proteins also signal partially via the NRG 1 sister clade, ADR 1. We propose that some NLR s signal via NRG 1 only, some via ADR 1 only and some via both or neither.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
