Transcriptional regulation of the CRK/DUF26 group of Receptor-like protein kinases by ozone and plant hormones in Arabidopsis

Conclusions: Combining expression analysis from multiple treatments with mutants altered in hormone biosynthesis or signalling suggest a model in which O(3) and salicylic acid (SA) activate separate signaling pathways that exhibit negative crosstalk. Although O(3) is classified as an abiotic stress to plants, transcriptional profiling of CRKs showed strong similarities between the O(3) and biotic stress responses
