Functional classification of Petunia transcripts associated to light and anthocyanin in comparison to Arabidopsis thaliana proteome; photoreceptor families (a), light-signal transduction pathways classified into gene ontology molecular function categories (b), anthocyanin-biosynthesis structural (c) and regulatory genes classified in transcription factor families (d). Assignments are based on GO Slim terms for genes were obtained from the Arabidopsis database site (ftp://ftp.arabidopsis.org/home/tair/Ontologies)
