Although these genes are not all assembled together in v.3 of the Populus trichocarpa genome they are all at or near the SDR (see text). Blocks of similar expression polarity can readily be seen. Bold marks three genes (MET1, CLC-C and TCP1) which appear to be duplicated but have reversed expression polarity. $similar expression trends were observed in data from Sanderson et al., 2018 at one individual time point late in flower development12.
