Gene Details:

• Gene ID:
• Gene Symbol: OeMST2
• Gene Name: monosaccharide transporter 2
• Genome:
• Species: Olea europaea

Functional Descriptions:

• OeMST2 Encodes a Monosaccharide Transporter Expressed throughout Olive Fruit Maturation.
• The encoded protein showed high affinity for D-glucose (Km, 25 μM) and was also able to recognize D-galactose and the analogs 3-O-methyl-D-glucose and 2-deoxy-D-glucose, but not D-fructose, D-arabinose, sucrose or D-mannitol. Maximal transport activity was high at acidic pH (5.0), and the initial D-[14C]glucose uptake rates were strongly inhibited by the protonophore carbonyl cyanide m-chlorophenylhydrazone, confirming that OeMST2 is a H+/monosaccharide transporter
• The expression of OeMST2 was studied during the ripening process. Transcript levels increased during fruit maturation, suggesting that OeMST2 takes part in the massive accumulation of monosaccharides in olive fruits. Monosaccharide:H+ transport system activity and OeMST2 expression were negatively regulated by glucose in suspension-cultured cells.
• Glucose-mediated OeMST2 repression was impaired by mannoheptulose, suggesting the involvement of a hexokinase-dependent signaling pathway.
