(Submitter supplied) Legumes interact with nodulating bacteria that convert atmospheric nitrogen into ammonia for plant use. This nitrogen fixation takes place within root nodules that form after infection of root hairs by compatible rhizobia. Using cDNA microarrays, we monitored gene expression in soybean (Glycine max) inoculated with the nodulating bacterium Bradyrhizobium japonicum 4, 8, and 16 days after inoculation (dai), time points that coincided with nodule development and the onset of nitrogen fixation. more...

(Submitter supplied) The ability of Bradyrhizobium japonicum and B. elkanii strains to utilize alkane and aromatic sulfonates as sole sources of sulfur for growth was investigated. All of the strains tested were able to utilize alkane sulfonates, but not aromatic sulfonates for growth. Whole-genome transcriptional profiling was used to assess B. japonicum USDA 110 genes involved in growth on alkane sulfonates, as compared to growth on sulfate and cysteine. more...

(Submitter supplied) The growth and persistence of rhizobia and bradyrhizobia in soils are negatively impacted by drought conditions. In this study, we used genome-wide transcriptional analyses to obtain a comprehensive understanding of the response of Bradyrhizobium japonicum to drought. Desiccation of cells resulted in the differential expression of 15 to 20% of the 8,480 B. japonicum open reading frames, with considerable differentiation between early (after 4 h) and late (after 24 and 72 h) expressed genes. more...

(Submitter supplied) PhyR is an unusual type of response regulator consisting of a receiver domain and an extracytoplasmic function (ECF) sigma factor-like domain. It was recently described as a master regulator of general stress response in Methylobacterium extorquens. Orthologues of this regulator are present in essentially all free-living Alphaproteobacteria. In most of them, phyR is genetically closely linked to a gene encoding an ECF sigma factor. more...

(Submitter supplied) The temporal expression of the 23 CfMNPV genes representing all four temporal classes including its 7 unique genes were determined by a modified oligonucleotide-based two-channel DNA microarray. Transcription of the non-coding (antisense) strands of some of the CfMNPV select genes including the polyhedrin gene was also detected by the array analysis. The expression of four host genes varied several fold throughout virus infection. more...

(Submitter supplied) The genome-wide transcriptional responses of the strictly aerobic -proteobacterium Gluconobacter oxydans 621H to oxygen limitation, to the absence of the cytochrome bc1 complex, and to low pH were studied using DNA microarray analyses. Oxygen limitation caused expression changes of 486 genes, representing 20% of the chromosomal genes. Genes with an increased mRNA level included those for terminal oxidases, the cytochrome bc1 complex, transhydrogenase, two alcohol dehydrogenases, heme biosynthesis, PTS proteins, proteins involved in cyclic diGMP synthesis and degradation, two sigma factors, flagella and chemotaxis proteins, several stress proteins, and a putative exporter protein. more...

(Submitter supplied) The euryhaline marine yeast Debaromyces hansenii is a model system for the study of genes related to osmotic stress. To study the transcriptional response of this organism to osmotic stress we have used the two color microarray based gene expression analysis of 6211 genes which constitutes the whole genome. Analysis was done at three time points after induction with salt (0.5h, 3h and 6h.) The mRNA level of 64 genes significantly increased at least 3-fold after induction with 2M NaCl whereas that of 45 genes was 3-fold diminished. more...

(Submitter supplied) Invasion of host tissue by the human fungal pathogen, Candida albicans is an important step during many forms of candidosis. However, not all C. albicans strains possess the same invasive and virulence properties. It is known for example that the two clinical isolates SC5314 and ATCC10231 differ in their ability to invade into host tissue and to cause infections. Strain SC5314 is invasive whereas strain ATCC10231 is non-invasive and strongly attenuated in virulence as compared to SC5314. more...
