2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (MCT) is a key enzyme involved in the 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway. In order to identify the MCT gene in mango, study the evolutionary route and expression pattern of MCT gene. In this study, with arabidopsis MCT gene as a reference, 14 MCT genes were searched from 12 plant genomes through the BLAST and HMMER. Then, we analyzed the conserved domains, phylogeny, and the expression of MCT gene in mango. The results showed that the MCT protein of mango contains a PF01128.19 domain, and the protein sequences of MCT gene is highly conserved. Phylogenetic analysis showed that the evolution of MCT genes were consistent with the evolutionary route of its species, the number of copies of the MCT genes was tightly controlled from algae to angiosperms. The results of expression analysis showed that the expression of MCT gene in the peels and flesh of developing mango were higher than that in the peels and flesh of mature mango in ‘guire-82’and ‘hongyu’. It is speculated that MCT gene play a more important role in the development of mango. These provide scientific basis for further elucidating the function of MCT gene in mango.
