Figure 7

The phylogeny of spermatophyte STSs in the TPS-a subfamily. Blue shadow represents the Rosanae STSs, yellow shadow represents the Asterids STSs, red shadow represents the monocot STSs, and orange shadow represents the magnoliid STSs. Red branches show the STSs with identical products, blue branches show the STSs with 1,11-cyclized functions and green branches show the probable HGT members from Santalum album. STSs producing 1,6-cyclized sesquiterpenes are marked with grey dots, and the neighbor STSs producing 1,10- or 1,11-cyclized products, respectively, are marked with black rectangles.
