Summary Plant disease is a major threat in agriculture and climate change predicted to intensify it. Above the optimal plant’s growth range, plant immunity particular immune responses induced by nucleotide-binding leucine rich repeat receptors (NLRs) are dampened, but underlying molecular mechanisms remains elusive. NLRs usually contain an N-terminal signaling domain, such as Toll/interleukin-1 receptor (TIR) which self-sufficient trigger signaling. By using inducible Arabidopsis transgenic lines expressing TIR-containing (TNLs) or corresponding isolated TIR domains from RPS4 flax L6 NLRs, we showed that downstream of TNL activation not affected elevation temperature. Conditional TNL- TIR-mediated follow same route at permissive temperature (EDS1/RNLs requirement salicylic acid sector). Yet, this pathway maintained under elevated (30°C) when TIRs, full-length TNLs. This work underlines need further study how impacted increase temperature, particularly important improve resilience resistance warming climate.
