“…It is probable (135) that ripening and hardening of palm seeds (unlike those from other taxa) is associated with extensive removal of galactosyl groups and that the "mannans" of Phytelephas macrocarpa, Hyphaene thebaica, and Phoenix dactylifera are laid down in this way (137). Mannans derived from seeds of certain other plant taxa have also been described (135,138).…”

“…Pure mannans are artificially defined as polysaccharides that contain more than 90% of mannose sugar residues ( Meier and Reid, 1982 ; Buckeridge, 2010 ). In higher plants, pure mannans are widespread in the cell wall of seeds, such as Schizolobium amazonicum , Coffea arabica beans, and Carum carvi asa ( Hopf and Kandler, 1977 ; Navarini et al, 1999 ; Petkowicz et al, 2001 ). In addition, pure mannan is also found in the Orchidaceae , such as Oncidium (cv.…”

Dendrobium officinale is a precious traditional Chinese medicinal plant because of its abundant polysaccharides found in stems. We determined the composition of water-soluble polysaccharides and starch content in D. officinale stems. The extracted water-soluble polysaccharide content was as high as 35% (w/w). Analysis of the composition of monosaccharides showed that the water-soluble polysaccharides were dominated by mannose, to a lesser extent glucose, and a small amount of galactose, in a molar ratio of 223:48:1. Although starch was also found, its content was less than 10%. This result indicated that the major polysaccharides in D. officinale stems were non-starch polysaccharides, which might be mannan polysaccharides. The polysaccharides formed granules and were stored in plastids similar to starch grains, were localized in D. officinale stems by semi-thin and ultrathin sections. CELLULOSE SYNTHASE-LIKE A (CSLA) family members encode mannan synthases that catalyze the formation of mannan polysaccharides. To determine whether the CSLA gene from D. officinale was responsible for the synthesis of mannan polysaccharides, 35S:DoCSLA6 transgenic lines were generated and characterized. Our results suggest that the CSLA family genes from D. officinale play an important role in the biosynthesis of mannan polysaccharides.

“…In higher plants, pure mannans are also widespread in non-leguminous seeds, such as Palmae, coffee beans, and some Umbelliferae species. [19][20][21] Recently, Petkowicz et al 22) also isolated a pure mannan from the seed of Schizolobium amazonicum, a Leguminosae species. The characteristics of pure mannans from seeds are mostly insoluble in water, and thus might contribute to the hardness of seeds to resist mechanical damage.…”

A water-soluble and neutral polysaccharide was extracted from the current pseudobulbs of Oncidium "Gower Ramsey" during the early inflorescence stage (flower stalk less than 4 cm) by hot water, precipitated with ethanol, and purified with an anion exchanger. From the data of monosaccharide composition and linkage and anomeric configuration analyses, the polysaccharide was identified as a linear beta-1-->4 linked mannan.
