The hot water extract of dry kinkéliba leaves (DKL) is a traditionally widely delighted and consumed beverage in West Africa, especially during the fasting periods. It is believed to possess various health benefit effects such as diuretic, purgative, digestive, anti-viral and anti-malarial properties. However, the preparation of this beverage has not been optimized so far, which may underestima...

Over 130 y have passed since Charles Darwin first discovered that the adventitious roots of English ivy (Hedera helix) exude a yellowish mucilage that promotes the capacity of this plant to climb vertical surfaces. Unfortunately, little progress has been made in elucidating the adhesion mechanisms underlying this high-strength adhesive. In the previous studies, spherical nanoparticles were obse...

The mucilage envelope of seeds has various functions including the provision of different ways for the dispersal of diaspores. Chemical composition and water content of the mucilage yield particular adhesive and frictional properties in the envelope that also influence the dispersal of seeds. To determine the physical properties of Plantago lanceolata seed mucilage we studied (1) composition, (...

Rhamnogalacturonan II (RG-II) is a structurally complex pectic polysaccharide that was first identified in 1978 as a quantitatively minor component of suspension-cultured sycamore cell walls. Subsequent studies have shown that RG-II is present in the primary walls of angiosperms, gymnosperms, lycophytes, and pteridophytes and that its glycosyl sequence is conserved in all vascular plants examin...

Concentrated binary mixtures of polymers in solution commonly exhibit immiscibility, resolving into two separate phases each of which is enriched in one polymer. The plant cell wall is a concentrated polymer assembly, and phase separation of the constituent polymers could make an important contribution to its structural organization and functional properties. However, to our knowledge, there ha...

The genus Fusarium is a species rich genus. Different media are required to study the morphological characters and classify different species, a time consuming technique. In this study pectic zymograms were used to identify species and form species of Fusarium isolates. Fusarium isolates (318) were obtained from different areas and hosts in Isfahan Province, Iran. Isolates were identified to sp...

except at corners and pit fields. In contrast, pectic side-chains Six monoclonal antibodies (mAbs) were used to map the were not detectable in the middle lamella of all parenchymal distribution of pectic epitopes in the cell walls of potato cell walls, except in the cortex where mAb LM6 (arabinan (Solanum tuberosum L. cvs Kardal and Karnico) tuber tissue epitope) labelled the entire wall. The g...

The cell-wall polysaccharides of Arabidopsis thaliana leaves have been isolated, purified, and characterized. The primary cell walls of all higher plants that have been studied contain cellulose, the three pectic polysaccharides homogalacturonan, rhamnogalacturonan I and rhamnogalacturonan II, the two hemicelluloses xyloglucan and glucuronoarabinoxylan, and structural glycoproteins. The cell wa...

AIMS To compare the in vitro fermentation properties of pectins and oligosaccharides derived from them in pure and mixed faecal cultures. METHODS AND RESULTS Specific growth rates of selected bacterial genera were calculated in pure culture. Bifidobacterium angulatum, B. infantis and B. adolescentis had higher growth rates on pectic oligosaccharides (POS I) derived from high methylated pectin...

background: pectin is composed of complex polysaccharides that can inhibit cancer metastasis and proliferation with no evidence of toxicity. in the present study, the apoptotic and necrotic effects of pectic acid (pa) on the rat pituitary gh3/b6 tumor cells has been investigated. methods: gh3/b6 cells were cultured in the ham’s f12 medium enriched with 15% horse serum and 2.5% fetal bovine seru...
