Phylogenic tree of Aux/IAA genes and their transcriptional responses to auxin in Brachypodium and Arabidopsis.

Brachypodium Aux/IAA family members were retrieved using the BLAST software. Protein sequences were aligned with MAFFT and similarities (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 the read count in IAA treatment divided by the average read count from all other treatments. Stat represents the p-value of the microarray experiment of Arabidopsis treated with IAA¹¹ or the FDR of RNA-seq data when the count of IAA treatment was compared with all other treatments. log₂ ratio is hatched in red if genes are up-regulated. cpm represents the average of log₂-scaled read counts per million reads in all experiments.
