The distribution of several arabinogalactan protein and pectic epitopes were studied during organogenesis in androgenic callus of wheat. In cell wall of mature and degenerating parenchyma cells, the arabinogalactan epitopes JIM4, JIM14, JIM16 or LM2 were expressed differently according to the cells
Selenium nanoparticles (SeNPs) were synthesized using arabinogalactans (LAG) as a formation scaffolding and particle stabilizer to investigate their anti-tumor properties. The formation, morphology, size, and in vitro biological activity of LAG-SeNPs were characterized by UV-vis, FT-IR, scanning
Arabinogalactan-proteins (AGPs) were isolated from the pistils of Nicotiana alata, deglycosylated, and the protein backbones fractionated by reversed-phase HPLC as previously reported. A major fraction, RT35 was isolated and peptide sequences were obtained after protease digestion. A gene-specific
A highly branched arabinogalactan isolated from Larix principis-rupprechtii and subjected to sulfation derivatization to promote their antitumor bioactivity. Several structural features of the sulfated arabinogalactans (S-LAG) were investigated: molecular weight, monosaccharide constitution, and
We have identified and characterised the temporal and spatial distribution of the homogalacturonan (HG) and arabinogalactan proteins (AGP) epitopes that are recognised by the antibodies JIM5, JIM7, LM2, JIM4, JIM8 and JIM13 during ovule differentiation in Larix decidua Mill. The results obtained
A precise control of sperm cells delivery and fusion to the egg cell and the central cell is fundamental for the accomplishment of successful double fertilization in flowering plants. This is mostly regulated by female gametophyte egg and central cells, which control the timing of synergids cell
Successful double fertilization and subsequent seed development in flowering plants requires the delivery of two sperm cells, transported by a pollen tube, into the embryo sac of an ovule. The embryo sac cells tightly control synergid cell death, and as a result the polyspermy block. Arabinogalactan
Apomixis results in asexual seed formation where progeny are identical to the maternal plant. In ovules of apomictic species of the Hieracium subgenus Pilosella, meiosis of the megaspore mother cell generates four megaspores. Aposporous initial (AI) cells form during meiosis in most ovules. The
The degradation of cell wall polysaccharides is highly associated with the softening process of banana. In this work, banana was treated by morin to delay softening during storage. Water-soluble polysaccharides were extracted from banana pulp at four storage stages. Their levels increased when the
