N-deacetylation of Sinorhizobium meliloti Nod factors increases their stability in the Medicago sativa rhizosphere and decreases their biological activity.
Nod factors excreted by rhizobia are signal molecules that consist of a chitin oligomer backbone linked with a fatty acid at the nonreducing end. Modifications of the Nod factor structures influence their stability in the rhizosphere and their biological activity. To test the function of N-acetyl groups in Nod factors, NodSm-IV(C16:2,S) from Sinorhizobium meliloti was enzymatically N-deacetylat...
متن کاملUranyle Complexes: synthesis, evaluation of biological activity
In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...
متن کاملSymbiotic Activity of Pea (Pisum sativum) after Application of Nod Factors under Field Conditions
Growth and symbiotic activity of legumes are mediated by Nod factors (LCO, lipo-chitooligosaccharides). To assess the effects of application of Nod factors on symbiotic activity and yield of pea, a two-year field experiment was conducted on a Haplic Luvisol developed from loess. Nod factors were isolated from Rhizobium leguminosarum bv. viciae strain GR09. Pea seeds were treated with the Nod fa...
متن کاملRhizobium symbiosis: nod factors in perspective.
Rhizobium and its allies (Azorhizobium, Bradyrhizobium, and Sinorhizobium) are Gram-negative bacteria that cause the development of root (and sometimes stem) nodules on plant hosts, which the bacteria inhabit as nitrogen-fixing endosymbionts. The early stages of this process, including gene expression in the bacterium and cell growth, division, and differentiation in the host, are mediated by s...
متن کاملEffect of Amino Acid Substitutions on Biological Activity of Antimicrobial Peptide: Design, Recombinant Production, and Biological Activity
Recently, antimicrobial peptides have been introduced as potent antibiotics with a wide rangeof antimicrobial activities. They have also exhibited other biological activities, including antiinflammatory,growth stimulating, and anti-cancer activities. In this study, an analog of MagaininII was designed and produced as a recombinant fusion protein. The designed sequence containe...
