Fig. 1From: Genome-scale transcriptional study of hybrid effects and regulatory divergence in an F1 hybrid Ruellia (Wild Petunias: Acanthaceae) and its parentsFlower morphologies and HPLC anthocyanin traces of three samples used in transcriptomic analysis. a Ruellia elegans (R. elegans). b Ruellia speciosa (R. speciosa). c F1 hybrid Ruellia elegans x R. speciosa (hybrid). d Results of HPLC analysis of corollas. In R. elegans, only pelargonidin was detected. No anthocyanins were detected in R. speciosa. Delphinidin and its derivatives malvidin and petunidin were detected in the hybridBack to article page
