Transcriptome analysis of tomato plants following salicylic acid-induced immunity against <i>Clavibacter michiganensis</i> ssp. <i>michiganensis</i>

Salicylic acid (SA) is known to be involved in the immunity against Clavibacter michiganensis ssp. (Cmm) that causes bacterial canker tomato. To identify candidate genes associated with SA-inducible Cmm resistance, transcriptome analysis was conducted via RNA sequencing tomato plants treated SA. SA treatment upregulated various defense-associated genes, such as PR and GST cotyledons. A comparison of SA- Cmm-responsive revealed both infection commonly a large number genes. Gene Ontology (GO) indicated GO terms plant were over-represented Cmm-induced The downregulated by cell cycle may growth trade-off through division. After treatment, several proteins predicted play role immune signaling, resistance gene analogs, Ca2+ sensors, WRKY transcription factors, transcriptionally upregulated. W-box element, which targeted WRKYs, promoter regions infection, supporting speculation WRKYs are important for SA-mediated Cmm. Prediction protein–protein interactions suggested encoding receptor-like kinases EF-hand an signaling. Thus, identified.
