Fig. 2From: Distinct expression and function of carotenoid metabolic genes and homoeologs in developing wheat grainsA neighbor-joining tree of wheat CCD1 and CCD4 homoeologs with selected plant carotenoid cleavage enzymes. Bootstrap values are shown next to the branches (1000 replicates). Wheat CCD1 and CCD4 homoeologs are highlighted in bold. CCD, carotenoid cleavage dioxygenase; LCD, lycopene cleavage dioxygenase; NCED, nine-cis-epoxycarotenoid dioxygenase; ZCD, zeaxanthin cleavage dioxygenaseBack to article page
