Galactans (Sylvarise Innovation)

Product Details

Galactans are complex polysaccharides composed of polymerized galactose units that serve critical structural and functional roles in plants, acting primarily as structural components of cell walls rather than direct immediate sources of energy. While plants produce their own food primarily through photosynthesis, creating glucose, Galactans specifically contribute to plant growth by influencing cell wall structure, aiding in stress tolerance, and serving as a stored carbon source in certain tissues.

ROLE OF GALACTANS IN PLANT GROWTH

Cell Wall Structure:
Galactan is a major component of pectin (rhamnogalacturonan I) in the primary cell walls of terrestrial plants. They are essential for plant development, particularly in cell elongation, as they modify cell wall properties.

Structural Regulation:
Galactans help control the crystallization of cellulose within the cell wall.

Growth Support:
Reductions in Galactans content have been linked to altered mechanical properties in plant tissues, such as slightly reduced stem diameters.

GALACTANS AS ENERGY/CARBON RESERVES

Raffinose Family Oligosaccharides (RFOs):
These are soluble sugars containing galactose that act as reserve carbohydrates in plants, especially in seeds, where they aid in seed germination and abiotic stress tolerance (desiccation, cold, heat).

Mobilization:
During germination, RFOs are hydrolysed by galactosidase into simple sugars, providing a source of energy for the developing seedling.

Storage in Tissues:
Plants can store these compounds in tuber or mesophyll cells, which can be broken down to support respiration.

Doses and recommendation

1.5–2.0 ml/ltr. of water.
