The hormone salicylic acid (SA) plays a crucial role in plant immunity by activating responses that arrest pathogen ingress. SA accumulation also penalizes growth, phenomenon visible mutants hyperaccumulate SA, resulting strong growth inhibition. An important question, therefore, is why healthy plants produce basal levels of this when defense are not activated. Here, we show unchallenged needed for the expression number immunity-related genes and receptors, such as RECEPTOR-LIKE PROTEIN 23 ( RLP23). This was shown depleting transgenic Arabidopsis lines through overexpression SA-inactivating hydroxylases DOWNY MILDEW-RESISTANT 6 (DMR6) or DMR6-LIKE OXYGENASE 1. RNAseq analysis revealed subset immune receptor signaling strongly reduced absence SA. biological relevance RLP23: In SA-depleted SA-insensitive plants, to RLP23 ligand, microbial pattern nlp24, were reduced, whereas flg22 remained unchanged. We hypothesize low system components enable early detection activation immunity.

SUMMARY Nucleotide‐binding leucine‐rich repeat (NLR) proteins are crucial intracellular immune receptors in plants, responsible for detecting invading pathogens and initiating defense responses. While previous studies on the evolution function of NLR genes were mainly limited to land evolutionary trajectory immune‐activating character algae remain less explored. In this study, genome‐wide gene analysis was conducted 44 chlorophyte species across seven classes charophyte five classes. A few but variable number genes, ranging from one 20, identified chlorophytes three charophytes, whereas no remaining algal genomes. Compared with genomes possess fewer or usually implying that expansion plants can be attributed their adaptation more complex terrestrial pathogen environments. Through phylogenetic analysis, domain composition conserved motifs profiling NBS domain, we detected shared lineage‐specific features between supporting common origin continuous green plant genes. Immune‐activation assays revealed both TNL RNL elicit hypersensitive responses Nicotiana benthamiana , indicating molecular basis activation has emerged early stage different types proteins. summary, results study suggest may have taken a role as ancestor plants.
