Ol. Ozeretskovskaya et al., XYLOGLUCAN-DERIVED OLIGOSACCHARIDE FRAGMENTS AS THE REGULATORS OF DEFENSE RESPONSES IN POTATO-TUBERS, Russian journal of plant physiology, 42(5), 1995, pp. 687-692
Oligosaccharides derived from xyloglucan by digestion with commercial
cellulase can act as elicitors or suppressors of the defense responses
in potato (Solanum tuberosum L.) tubers. The fragments with high mole
cular weights, formed at the first stages of hydrolysis, showed an eli
citor activity. During further hydrolysis, the fragments of low molecu
lar weights appeared, characterized by a suppressor effect. The fracti
ons of suppressors inhibited the defense responses in potato tubers at
extremely low concentrations.
