Phylogenetic tree based on amino acid sequences of LCYB from six monocotyledonous species [Crocus sativus (ADA82241.1), Narcissus pseudonarcissus (ACT78995.1), Narcissus tazetta (AFH53820.1), Sandersonia aurantiaca (AAL92175.1), Asiatic hybrid lily (Lilium spp.) (BAH10590.1), Lilium lancifolium (JF304153)] and six dicotyledonous species [Capsicum annuum (ADH04271.1), Solanum lycopersicum (NP001234226.1), Ipomoea kenyan (BAI47577.1), Citrus sinensis (AAM21152.1), Phaseolus vulgaris (ADX60450.1), Lycium barbarum (AAW88382.1)], NSY from Solanum tuberosum (Q9M424.1) and S. lycopersicum (CAB93342.1), CCS from C. annuum (Q42435.1) and L. lancifolium (JF304153), and LCYE from N. tazetta (AFG19394.1). LCYE was chosen because it is a closely related lycopene cyclase protein that catalyzes the formation of ε-rings in the β,ε-branch of the carotenoid biosynthesis pathway. The GenBank accession number for each gene is given in parentheses. Values displayed at the nodes indicate the percentage consensus support as calculated using a bootstrapping test with 1,000 replications.
