A water soluble gum polysaccharide was isolated from Murraya paniculata fruits. Hydrolytic experiments, methylation analysis, periodate oxidation studies and NMR data revealed that the polysaccharide was extensively branched and it consisted of 1,3-, and 1,3,6-linked beta-D-galactopyranosyl units, terminal beta-D-galactopyranosyl units and terminal(More)
The water-soluble polysaccharides isolated from the vascular gel of Musa paradisiaca, were fractionated via anion exchange chromatography into four fractions. Fractionated polymers contained arabinose, xylose and galacturonic acid as major sugars, together with traces of galactose, rhamnose, mannose and glucose residues. Methylation analysis revealed the(More)
Bacteria and archaea have evolved with the ability to fix atmospheric dinitrogen in the form of ammonia, catalyzed by the nitrogenase enzyme complex which comprises three structural genes nifK, nifD and nifH. The nifK and nifD encodes for the beta and alpha subunits, respectively, of component 1, while nifH encodes for component 2 of nitrogenase. Phylogeny(More)
The MYB gene family represents one of the largest groups of transcription factors in plants. Recent evidences have also demonstrated key role of MYB transcription factors in regulating the expression of major genes involved in the biosynthesis of phenylpropanoid compounds which confer biotic and abiotic stress tolerance in plant species. However, no(More)
The rbcL (ribulose-1,5-biphosphate carboxylase oxygenase) gene plays a crucial role in carbon fixation. Previous studies shed light on its evolutionary relationship among different Phyla. Here, authors have done a comparative study of rbcL genes among proteobacteria, archaea, cyanobacteria and plants based on their compositional variations (GC%, amino acid(More)
