Table I. CYP720B members identified in transcriptomes and genomes of different spruce and pine species.

Using Sitka spruce (Ps) CYP720B cDNA reference sequences (Hamberger et al., 2011), CYP720B members were identified as present (+) in white spruce (Pg), Norway spruce (Pa), loblolly pine (Pt), lodgepole pine (Pc), and jack pine (Pb) transcriptome (T) or genome (G) sequences. Not included are intraspecific minor variants, which may represent allelic differences, as shown in Figure 1.
