2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase (MDS) is a key enzyme involved in the 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway. In order to identify the MDS family genes in mango, study the evolution and expression patterns of MDS family genes. In this study, 16 MDS family genes were downloaded from 13 plant genomes by homologous search method and carried out the protein domains, phylogeny and the expression analysis of MDS family genes in mango. The results of protein domain analysis showed that PF02542.16 domain in the protein sequences of mango MDS family genes respectively. The construction of phylogenetic tree found that the MDS family genes in mango evolved after the formation of dicotyledon, and are most closely to the MDS gene in Citrus sinensis. The expression analysis showed that the MDS family genes of mango had the highest expression in the flesh of 'Guifei' at the ripe stage, the second is ' Tainong ', with the lowest expression in 'Jinhuang', and the difference is significant. This research provided a scientific basis for the further analysis of function of mango MDS family genes in terpenoid synthesis pathway.
