Abstract

Magnesium transporters (MGTs) play a prominent role in the absorption, transport and storage of magnesium in plant cells. In the present study, MGT gene family members were identified and characterized in two species of cucurbitaceae, including C. sativus and C. lanatus. 20, 19, and 20 MGT genes were recognized in C. lanatus, C. sativus, and C. melo, respectively. According to physicochemical properties, the members of each sub-class of MGTs in the species of cucurbitaceae showed the close relationship. Proteins from NIPA were identified as hydrophilic proteins with high stability. Based on phylogenetic analysis, MGT family members were classified into three groups, and NIPAs showed more diversity. Besides, duplication events were not identified between the MGT members in C. lanatus, and C. sativus. According to pocket analysis, residues such as L, V, S, I, and A were frequently observed in the binding sites of MGT proteins in both species. The prediction of post-translation modifications revealed that MSR2 proteins have high phosphorylation potential than other sub-classes in both studied plants. The expression profile of MGTs showed that MGTs are more expressed in root tissues. In addition, MGTs showed differential expression in response to abiotic/biotic stresses as well as hormone application and NIPAs were more induced in response to stimuli in watermelon. The results of this study, as the primary work of MGT gene family, can be used in programs related to cucurbitaceae breeding.
