Molecular phylogenetic analysis of Vitis vinifera and Arabidopsis CCD and NCED gene models by the Maximum Likelihood method. Multiple sequence alignment for full-length carotenoid cleavage dioxygenases was inferred using MUSCLE . The evolutionary history was inferred by using the Maximum Likelihood method based on the JTT matrix-based model . The bootstrap consensus tree inferred from 100 replicates  is taken to represent the evolutionary history of the taxa analyzed . Branches corresponding to partitions reproduced in less than 70% of bootstrap replicates were collapsed. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (100 replicates) is shown next to the branches . Initial tree(s) for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using a JTT model, and then selecting the topology with superior log likelihood value. The analysis involved 20 amino acid sequences. The coding data was translated assuming a Standard genetic code table. All positions containing gaps and missing data were eliminated. There were a total of 225 positions in the final dataset. Evolutionary analyses were conducted in MEGA5 . Arrows point toward recommended Vitis symbols. Asterisks indicate redundant synonyms.
