New infertility therapy effects of polysaccharides from Althaea officinalis leaf with emphasis on characterization, antioxidant and anti-pathogenic activity. International journal of biological macromolecules, 2020, Feb-15, Volume: 145 Characterization, antioxidant, anti-pathogenic and infertility therapy effects of polysaccharides from Althaea officinalis (marshmallow) leaf (AOLPS) were investigated. AOLPS was fractionated using ion-exchange chromatography, affording fractions of AOLPS-1, AOLPS-2, AOLPS-3 and AOLPS-4. The fractions were mainly composed of d-galactopyranose (α-(1 → 4)-glycosidic bond) with the average molecular weight of 1220 Topics: Althaea; Anti-Infective Agents; Antioxidants; Calorimetry, Differential Scanning; Fertility Agents; Free Radical Scavengers; Infertility; Molecular Weight; Pectins; Plant Extracts; Plant Leaves; Polysaccharides; Spectroscopy, Fourier Transform Infrared	2020
Temporal and spatial distribution of pectin epitopes in differentiating anthers and microspores of fertile and sterile sugar beet. Plant & cell physiology, 2004, Volume: 45, Issue:5 We studied the possible involvement of several pectin epitopes in anther differentiation and microsporogenesis in fertile and cytoplasmically male sterile sugar beets. The spatial and temporal distribution of five structural motifs were traced with a panel of monoclonal antibodies in six stages: premeiosis, meiotic prophase, young and mature tetrads, young and expanding microspores. The composition of the walls of sporogenous cells and meiocytes differed than that in the tapetum, as evidenced by the presence of alpha-Fuc(1-->2)-beta-Gal and alpha-(1-->5)-L-Ara epitopes binding CCRC-M1 and LM6 antibodies. At meiotic prophase, the meiocyte walls were additionally marked by the appearance of poorly methyl-esterified domains of homogalacturonan and of (1-->4)-beta-Gal residues, detected by JIM5 and LM5. Some constituents of the meiocyte wall which reacted with JIM5 and JIM7 persisted on the surface of the special callose sheath during tetrad development. In newly formed primexine and exine layers of tetrads and microspores, epitopes that were bound by JIM5, JIM7 and LM5 were abundant. No differences in the deposition or relative abundance of pectins were found between fertile and sterile anthers until microspore release from the callose. Later, at the time of abortion, sterile microspores had much larger amounts of epitopes detected by JIM5 than their fertile counterparts.
