From: Multi-species transcriptome analyses for the regulation of crocins biosynthesis in Crocus
Expression levels of unigenes assigned to the carotenoid and apocarotenoid biosynthetic pathways in Crocus. a) An overview of the crocins biosynthesis pathway enzymes and metabolites in Crocus. Homologues genes encoding for the different enzymes were identified in the transcriptome assembly. b) Expression analyses of genes encoding from the enzymes of the carotenoid biosynthesis pathway identified in the transcriptomes from I and II stages of the three Crocus species. c) Expression analyses of homologues to carotenoid cleavage enzymes (CCD1, CCD2, CCD4, CCD7, CCD8 and NCED), to the β-carotene isomerase D27 and UGT74AD2 genes identified in the six transcriptomes. d) Expression analyses of ALDH genes homologues identified in the six transcriptomes analysed
