“…4 ). These results are in agreement with previous studies reported in some leaves up to now, in Mesembryanthenum crystallinum ( M’sakni et al, 2006 ), in two plants endemic to central Africa, Fleurya aestuans (Linnaeus) Miquel and Phragmenthera capitata (Spreng) ( Aboughe Angone et al, 2009 ) and in the medicinal tree Cola cordifolia ( Austarheim et al, 2014 ) in which rhamnogalacturonan type I structure is variable.…”

The pectin polysaccharides from leaves of Argania spinosa (L.) Skeels, collected from Stidia area in the west coast of northern Algeria, were investigated by using sequential extractions and the resulting fractions were analysed for monosaccharide composition and chemical structure. Water-soluble pectic (ALS-WSP) and chelating-soluble pectic (ALS-CSP) fractions were obtained, de-esterified and fractionated by anion-exchange chromatography and characterized by sugar analysis combined with methylation analysis and 1H and 13C NMR spectroscopy. The data reveal the presence of altering homogalacturonan (HG) and rhamnogalacturonan I (RG-I) in both pectin fraction. The rhamnogalacturonan I (RG-I) are consisted of a disaccharide repeating unit [→ α-D-GalpA-1,2-α-L-Rhap-1,4 →] backbone, with side chains contained highly branched α-(1 → 5)-linked arabinan and short linear β-(1 → 4)-linked galactan, attached to O-4 of the rhamnosyl residues.

“…(Matsunaga et al, 2004). Since the early reports of borate-cross-linked RG-II dimers (dRG-II, B-dRG-II or dRG-II-B) in radish roots, sugar beet pulp, red wine, sycamore cells and etiolated pea stems (Albersheim et al, 1996), a widely held view is that RGs-II exist predominantly as dRG-II in muro rather than as RG-II monomers (mRG-II) (O'Neill et al, 2004;Pérez, Rodríguez-Carvajal, & Doco, 2003), which is corroborated by later work (Aboughe-Angone et al, 2009;Hilz, Williams, Doco, Schols, & Voragen, 2006;Yapo, 2007). RGs-II were originally purified from the soluble products of Endo-PG-digested sycamore CWM by IEC/SEC fractionations (Darvill et al, 1978).…”

“…Since the early reports on borate-cross-linked RG-II dimers (dRG-II or B-dRG-II) in the PCWs of Raphanus sativus (radish) roots, Beta vulgaris (sugar beet) pulp, suspensioncultured A. pseudoplatanus (sycamore) cells, etiolated pea stems, and red wine [41][42][43][44], a widely held view is that this polysaccharide type exists predominantly in the form of dRG-II in muro [9,12,40,45], which is supported by later work [10,46,47]. In vitro, dRG-II formation is a selfassembly process which is the result of the cross-linking of two mRG-II chains via the two Apif -containing A-side chains on both RG-II macromolecule strands, with theoretically two possible diastereoisomers [48,49].…”

Rhamnogalacturonan II (RG-II) is a type of block copolymer of complex pectins that represents a quantitatively minor component of the primary cell walls of land (vascular) plants. The structural composition of RG-II is almost totally sequenced and appears to be remarkably conserved in all tracheophytes so far examined. The backbone of RG-II, released from complex (cell wall) pectins by endo-polygalacturonase (Endo-PG) treatment, has been found to contain up to 15 (1→4)-linked-α-D-GalpA units, some of which carry four well-defined side chains, often referred to as A-, B-, C-, and D-side chains. Nevertheless, the relative locations on the backbone of these four branches, especially the A chain, remain to be ascertained. A combination of different data suggests that neither the terminal nonreducing GalA nor the contiguous GalA unit is likely to be the branching point of the A chain, but probably the ninth GalA residue from the reducing end, assuming a minimum backbone length of 11 (1→4)-linked-α-d-GalpA. The latest reports on RG-II are here highlighted, with a provided update for the macrostructure and array of functionalities.
