Phylogenic tree of PR1, its orthologs and transcriptional responses to SA treatment in Brachypodium and Arabidopsis.

Brachypodium PR1-like genes were retrieved using the BLAST software. Similarities in protein sequences (percentage identity) are shown as a phylogenetic tree. Brachypodium genes are shown in red and Arabidopsis genes in black. log₂ ratio represents the gene expression ratio between read counts from SA treatment divided by the average read counts from all other treatments. Stat represents the p-value of the microarray experiment. Arabidopsis treated with SA for 3 h¹¹ for Arabidopsis genes or FDR of RNA-seq data when the counts from SA treatment were compared with all other treatments for Brachypodium genes. log₂ ratio is hatched in red if genes are up-regulated and in blue if down-regulated. cpm represents the log₂-scaled read count per million reads of RNA-seq data from all treatments.
