“…Several approaches have been described in the literature for pectin depolymerization, including physical treatments, such as electron beam irradiation, 29 free-radical hydrolysis, 38 physico-chemical processes, 25,37 enzymatic hydrolysis either in submerged systems 8,11,12,15,21–23,35 or with immobilized enzymes 24,31 and even microbial fermentation using wild 10 or genetically modified microorganisms. 32,34 In addition, combined technologies such as enzymatic hydrolysis and high hydrostatic pressure 7 or enzymatic hydrolysis and chemical de-esterification 14 were also employed for the production of di- and tri-galacturonides and mixtures of OGalA with DP1–8, respectively.…”

“…In plant cell walls, during reaction of H 2 O 2 with copper (II), free hydroxyl radicals are produced that can cleave plant polysaccharides such as xyloglucan [81] with high yield of low molecular mass fraction and good reproducibility. This nonenzymatic mechanism of polysaccharide depolymerization occurs during increase in cell size, fruit ripening, and organ abscission [82,83].…”

This review substantiates the need to study the plant oligoglycome. The available information on oligosaccharins - physiologically active fragments of plant cell wall polysaccharides - is summarized. The diversity of such compounds in chemical composition, origin, and proved biological activity is highlighted. At the same time, plant oligosaccharides can be considered as outsiders among elicitors of various natures in research intensity of recent decades. This review discusses the reasons for such attitude towards these regulators, which are largely connected with difficulties in isolation and identification. Together with that, approaches are suggested whose potentials can be used to study oligosaccharins. The topics of oligosaccharide metabolism in plants, including the ways of formation, transport, and inactivation are presented, together with data on biological activity and interaction with plant hormones. The current viewpoints on the mode of oligosaccharin action - perception, signal transduction, and possible "targets" - are considered. The potential uses of such compounds in medicine, food industry, agriculture, and biotechnology are discussed.

“…Oligogalacturonides (OGs) are oligomers of 1,4-linked alpha-D-galacturonosyl residues, a major component of pectin, that are produced by the degradation of homogalacturonan [ 1 , 2 , 3 ]. OGs have been reported to affect plant metabolism in a variety of ways, including eliciting a wide range of defense responses that confer protection against plant pathogens [ 3 , 4 , 5 ], regulating plant growth and development [ 6 , 7 ], and acting as signaling molecules in plants by activating a Ca 2+ -mediated signaling pathway [ 5 , 8 ].…”

Oligogalacturonides (OGs) are a bioactive carbohydrate derived from homogalacturonan. The OGs synthesized in this study significantly inhibited the mycelial growth of Rhizoctonia solani AG-4HGI in vitro, even at a low concentration (10 mg/L). The seed vigor test demonstrated that the application of 50 mg/L OGs to sugar beet seeds significantly increased average germination percentage, germination energy, germination index, and seedling vigor index. The same concentration of OGs also improved the seedling emergence percentage of sugar beet when seeds were sown in soil inoculated with D2 and D31 isolates, respectively. The lesion diameter on mature sugar beet roots caused by R. solani AG-4HGI isolates D2 and D31 also decreased by 40.60% and 39.86%, respectively, in sugar beets roots first treated with 50 mg/mL OGs in the wound site, relative to lesion size in untreated/pathogen inoculated wounds. Sugar beet roots treated with 50 mg/mL OGs prior to inoculation with the D2 isolate exhibited up-regulation of the defense-related genes glutathione peroxidase (GPX) and superoxide dismutase (SOD) by 2.4- and 1.6-fold, respectively, relative to control roots. Sugar beet roots treated with 50 mg/mL OGs prior to inoculation with D31 exhibited a 2.0- and 1.6-fold up-regulation of GPX and SOD, respectively, relative to the control. Our results indicate that OGs have the potential to be used for the protection of sugar beet against R. solani AG-4HGI.
