Definition
Oligosaccharins are small carbohydrate fragments derived from the degradation of cell wall polysaccharides. They play crucial roles in plant defense and developmental processes by acting as signaling molecules.
5 Must Know Facts For Your Next Test
Oligosaccharins are produced through enzymatic hydrolysis of complex carbohydrates in plant cell walls.
These molecules can elicit defense responses against pathogens by activating plant immune systems.
Oligosaccharins influence plant growth and development, including processes like flowering and root formation.
They can modulate the levels of other hormones, such as auxin and ethylene, enhancing or suppressing their effects.
Their signaling mechanism involves binding to specific receptors on the cell surface, triggering intracellular pathways.
