The maximum likelihood (ML) phylogenetic tree a shows the occurrence of AORchl, AORcyt-I, and AORcyt-II genes in dominant plant species. Asterisks and coloring of the branch labels indicate species emitting predominantly isoprene, monoterpenes, or both. Numbers at tree branches indicate node bootstrap support. Green branch coloring indicates the presence of plastid-targeting peptides (TP) in the corresponding AOR sequences. Basal nodes of the AORchl, AORcyt-I, and AORcyt-II ortholog clusters are labeled with solid circles. The scale bar below the tree shows branch length. Box plots b show tissue-specific expression of AORchl and AORcyt-II genes in gray poplar (Populus × canescens). Error bars show the minimum/maximum.
