Galactinol
Based on 1 Customer Validation
Galactinol is a disaccharide carbohydrate serving as a galactosyl donor, which belongs to the raffinose family oligosaccharide pathway and acts as an important osmoprotectant. Galactinol not only induces disease resistance in plants against fungal and bacterial pathogens, but also significantly enhances plant tolerance to abiotic stresses such as drought, high salinity, low temperature and oxidative damage. In addition, Galactinol has the ability to scavenge hydroxyl radicals, can act as a signaling component for root colonization-induced systemic resistance, and is positively correlated with seed longevity in various crops, making it a potential biomarker for evaluating seed vigor. Therefore, Galactinol can be used in the research of various plant diseases including fungal leaf spot, bacterial angular leaf spot, gray mold and soft rot.

Biological Activity
Galactinol (0.5-10 mM) potently scavenges hydroxyl radicals in vitro with an ID50 of 3.1 mM and a second-order rate constant of 7.8 × 109 M-1s-1[1].
Galactinol (40.4 ± 18.8-1,727 ± 366 nmol/g fresh weight; endogenous production via transgene overexpression) in Arabidopsis thaliana ecotype Columbia plants confers protection against methylviologen-induced oxidative stress under control light intensity, as evidenced by preserved PSII activity, reduced lipid peroxidation, and maintained antioxidant pool levels[1].
Galactinol (40.4 ± 18.8-1,727 ± 366 nmol/g fresh weight; endogenous production via transgene overexpression) in Arabidopsis thaliana ecotype Columbia plants confers protection against methylviologen-induced oxidative stress under high light intensity, as evidenced by reduced visible leaf injury, preserved PSII activity, and reduced lipid peroxidation[1].
Galactinol (40.4 ± 18.8-1,727 ± 366 nmol/g fresh weight; endogenous production via transgene overexpression) in Arabidopsis thaliana ecotype Columbia plants confers protection against salinity stress, as evidenced by reduced visible leaf bleaching, preserved PSII activity, and reduced lipid peroxidation[1].
Galactinol (0.5-5 mM; root application) confers enhanced resistance to fungal and bacterial pathogens, tolerance to drought and high-salinity stress at 0.5 mM, while 5 mM induces expression of specific defense-related genes in wild-type tobacco[2].
