Comparison of the membrane composition of Spiroplasma citri and the corn stunt Spiroplasma.
Components of membranes isolated from Spiroplasma citri and corn stunt spiroplasma grown at 28 degrees C were analyzed. On a protein basis, lipid phosphorus was lower and cholesterol was higher in S. citri. Only minor differences between the two species were found in fatty acid composition, reduced nicotinamide adenine dinucleotide diaphorase, and adenosine triphosphatase.
متن کاملAntigenic relatedness between the spiralins of Spiroplasma citri and Spiroplasma melliferum.
Four spiralins were compared by rocket immunoelectrophoresis, quantitative immunoblotting techniques, and the spiroplasma deformation test with the use of antispiralin (polyclonal) monospecific antibodies. This investigation revealed that the spiralins of Spiroplasma citri and S. melliferum are antigenically related and that probably no more than two epitopes simultaneously saturable with antib...
متن کاملViruses of Spiroplasma citri and their possible effects on pathogenicity.
Strains of Spiroplasma citri are persistently infected by viruses which have been separated into three groups on the basis of their morphology. The properties of each group are reviewed. Viruses normally only appear in spiroplasma cultures but recently all three types of particle have been identified in cells of a single strain of S. citri within an infected plant. Replication of a short-tailed...
متن کاملSpiroplasmas of Group I: the Spiroplasma citri cluster.
We propose that Group I spiroplasmas be subdivided into seven, rather than four, subgroups. The seven subgroups showed remarkable homogeneity when several representative strains were compared. Hybridization reactions between DNAs of representative strains within subgroups were generally at least 90 percent, and usually at least 80 percent co-migrating cell proteins were found. In addition, when...
متن کاملEvaluation of Biochemical Composition and Enzyme Activities in Browned Arils of Pomegranate Fruits
Aril browning threatens production, consumption, and exports of pomegranates, because affected fruit cannot be externally distinguished from healthy fruit. This study compared the mineral, biochemical composition, and related enzyme activities in affected brown arils with healthy ones in ‘Malase Saveh’ pomegranates. The results indicated that concentrations of Cu in the aril and K, Mg, and Mn i...
