TranscriptomicsResponse of Blastocladiella emersonii to hypoxia, iron deprivation and geldanamycin treatment followed by hypoxia.
Due to its aquatic saprophytic lifestyle, the fungus Blastocladiella emersonii seems to be adapted to low aerated environments and thus can be an interesting model of study of the hypoxic stress response. Iron deprivation, a hypoxia-mimicking stimulus due to HIF-1 stabilization, and geldanamycin, th...

TranscriptomicsGlobal gene expression analysis during sporulation of the aquatic fungus Blastocladiella emersonii
Blastocladiella emersonii life cycle presents a number of drastic biochemical and morphological changes, mainly during two cell differentiation stages: the germination and the sporulation. To investigate the transcriptional changes taking place during the sporulation phase, which culminates with the...

TranscriptomicsGene expression during germination in the Chytridiomycete Blastocladiella emersonii
To investigate global changes in gene expression during B. emersonii germination process, we constructed cDNA microarrays containing 3,563 putative unique genes. Analyses were carried out during germination induced under various environmental conditions. Microarray data revealed that 26% of them are...

TranscriptomicsRole of σ54 in the regulation of genes involved in biogenesis of type I and type IV pili in Xylella fastidiosa
The phytopathogen Xylella fastidiosa produces two classes of pili, long type IV pili and short type I pili, which are involved in motility and adhesion. In this work, we have investigated the role of σ54 factor and its involvement in the regulation of fimbrial biogenesis in X. fastidiosa. An rpoN n...

TranscriptomicsTranscriptome analysis of the phytopathogen Xylella fastidiosa in response to salt and osmotic stress
The global transcriptional response of the phytopathogenic bacterium X. fastidiosa to a sudden increase in salinity and osmolarity of the medium was investigated using DNA microarrays. Time-course experiments were carried out by exposing bacterial cells to high salinity (250 mM NaCl) and high osmola...

TranscriptomicsGlobal gene expression under nitrogen starvation in Xylella fastidiosa: contribution of the ?54 regulon
Background: Xylella fastidiosa, a Gram-negative fastidious bacterium, grows exclusively in the xylem of several plants, causing diseases such as citrus variegated chlorosis. As the xylem sap contains low concentrations of amino acids and other compounds, X. fastidiosa needs to cope with nitrogen lim...
