Low-resolution sequencing of Rhodobacter sphaeroides 2.41T: chromosome II is a true chromosome

Article Abstract:

Species of the facultative photoheterotroph Rhodobacter sphaeroides 2.4.1T is made up of the CI and CII chromosomes. These chromosomes were subjected to a low-redundancy sequencing strategy to generate an overview of the types of genes encoded by the CII. Findings showed that R. sphaeroides 2.4.1T has two circular chromosomes, ~3.0 and ~0.9 Mpb. This revealed that multiple chromosomes exist in a bacterial genera. Furthermore, the numerous isolates of R. sphaeroides show that most appear to have two chromosomes which vary in size and number of rnrn operons.

Genetic polymorphism and taxonomic infrastructure of the Pleurotus eryngii species-complex as determined by RAPD analysis, isozyme profiles and ecomorphological characters

Article Abstract:

Research has been conducted on the Pleurotus eryngii species-complex which includes edible mushroom populations growing in the Mediterranean area. The elucidation of the systematics and the assessment of the European Pleurotus taxa which is associated with the umbellifers have been investigated and reported.

New aspects of the glucose activation of the H (super)+ -ATPase in the yeast Saccharomyces cerevisiae

Article Abstract:

Research has been conducted on the plasma membrane ATPase from Saccharomyces cerevisiae. The glucose-induced activation of this ATPase has been investigated and the results confirm protein kinase C involvement.
