Magnesium transporter Gene Family: Genome-Wide Identification and Characterization in Theobroma cacao, Corchorus capsularis, and Gossypium hirsutum of Family Malvaceae

Magnesium (Mg) is an element involved in various key cellular processes plants. Mg transporter (MGT) genes play important role magnesium distribution and ionic balance maintenance. Here, MGT family members were identified characterized three species of the plant Malvaceae, Theobroma cacao, Corchorus capsularis, Gossypium hirsutum, to improve our understanding their structure, regulatory systems, functions, possible interactions. We 18, 41, 16 putative non-redundant from genome T. G. C. respectively, which clustered into groups maximum likelihood tree. Several segmental/tandem duplication events determined between genes. MGTs appear have evolved slowly under a purifying selection. Analysis gene promoter regions showed that high potential respond biotic/abiotic stresses hormones. The expression patterns revealed response P. megakarya fungi whereas differential tissues several abiotic stresses, including cold, salt, drought, heat stress hirsutum. co-expression network indicated auxin-responsive lipid metabolism, cell wall organization, photoprotection can interact with MGTs.
