2.4.1.82	physiological function	RAFS mutant maize plants completely lack raffinose, hyper-accumulate galactinol and are more sensitive to drought stress than the corresponding null-segregant plants. RAFS overexpression in Arabidopsis thaliana enhances drought stress tolerance by increasing myo-inositol levels via RAFS-mediated galactinol hydrolysis in the leaves due to sucrose insufficiency in leaf cells and also enhances raffinose synthesis in the seeds. Supplementation of sucrose to detached leaves converts RAFS from hydrolyzing galactinol to synthesizing raffinose	Zea mays
