Expression analysis of Aspergillus nidulans AN1599 (PbcR) overexpression mutant

ABSTRACT: Investigation of whole genome gene expression level changes in Aspergillus nidulans AN1599 (PbcR) overexpression mutant, compared to the FGSC A4 wild-type strain. Overexpression of the Zn(II)2Cys6 M-bM-^@M-^Stype transcription factor, AN1599.4 (PbcR, pimaradiene biosynthetic cluster regulator), activates a secondary metabolite gene cluster in Aspergillus nidulans. Activation of the pathway in Aspergillus nidulans lead to a production of ent-pimara-8(14),15-diene. 12x135K array of two separate cultures of FGSC A4 and two separate cultures of oe:AN1599(PbcR) with three separate RNA extractions from each culture. Each 135K array measures expression level of 10,546 genes with 6 probes/transcript. In addition, the array format contains tiling probes for 36 longer transcripts. All probes are in duplicates, giving the total number of 137,562 probes per array.

Expression analysis of Aspergillus nidulans OE::rsmA

Project description:Investigation of whole genome gene expression level changes in Aspergillus nidulans OE::rsmA compared to wild-type RDIT9.32 (veA). A twelve array study using total RNA recovered from six separate cultures of Aspergillus nidulans wild-type RDIT9.32 (veA) and six separate cultures of Aspergillus nidulans overexpressing rsmA (restorer of secondary metabolism A), using custom-designed, four-plex arrays. The experiment was divided into two runs. In the first run, three biological replicates each of Aspergillus nidulans wild-type RDIT9.32 (veA) and Aspergillus nidulans carrying a plasmid overexpressing rsmA under the control of the gpdA promoter were assayed. In the second run, three biological replicates each of Aspergillus nidulans wild-type RDIT9.32 (veA) and Aspergillus nidulans overexpressing rsmA at the native locus under the control of the gpdA promoter were assayed.

Expression analysis, A. actinomycetemcomitans wild type (JP2) vs CRP deletion mutant both grown anaerobically.

Project description:The goal of this analysis is to define the anaerobic regulon for the global transcription factor CRP (catabolite repressor protein) in the periodontal pathogen Aggregatibacter actinomycetemcomitans. The objectives were met by comparing the mRNA profile of a wild type strain, JP2, to that of an isogenic mutant deleted of the CRP gene. Both strains were grown anaerobically. A three biological replicates study using total RNA recovered from three separate cultures of wild-type Aggregatibacter actinomycetemcomitans strain JP2 and three separate cultures of strain AAM167, an isogenic deletion mutant in which the gene for cAMP-Receptor-Protein (CRP) has been replaced by a spectinomycin resistance gene cassette. The cells were grown anaerobically in pairs (wild type paired with mutant). Each chip measures the expression level of 2,116 genes from A. actinomycetemcomitans strain HK1651. There were 11 different 60-mer probes /gene for 94% of the genes, and the entire probe set (22,537 probes) was replicated (technical replicates) three times on each array. Each probe set is contained on a quarter of a chip and there were also 4,426 random probes per array. Wild type and mutant RNAs from cultures #1 and #2 were hybridized to the same chip and the RNAs from cultures #3 were hybridized in different quadrants of a second chip.

Expression analysis of Ralstonia solanacearum strain GMI1000 at 20°C and 28°C in rich medium (CPG) and in planta

Project description:Investigation of whole genome gene expression level changes in the bacterial wilt pathogen Ralstonia solanacearum, strain GMI1000 at 20°C and 28°C in culture and in planta. The tropical strain GMI1000 cannot wilt tomato plants at 20°C although it can cause full-blown disease at 28°C. A 16 array study using total RNA recovered from the following: 8 separate cultures of Ralstonia solanacearum strain GMI1000 grown in rich medium-CPG (4 grown at 20°C and 4 grown at 28°C) 8 separate in planta samples of Ralstonia solanacearum strain GMI1000 harvested from diseased tomato plants cv. BonnyBest (4 recovered from plants grown at 20°C and 4 from plants grown at 28°C) Each array (4-plex format) measures the expression level of 5061 genes from Ralstonia solanacearum strain GMI1000 with 2 to 6, 40-70 mer probes per gene, with two-fold technical redundancy. The arrays also contain probes for intergenic regions with no technical replicates.

Expression data from Aspergillus nidulans FGSCA26 and SirAdelta grown for 24,48, and 72h

Project description:The sirA gene encodes a member of sirtuin protein that is NAD(+)-dependent histone deacetylase (HDAC) and ubiquitous in eukaryote. DNA microarray analyses for Aspergillus nidulans FGSCA26 (WT) strain and Gene disruptant of sirA (SirAd) indicated that genes for synthesizing secondary metabolic products such as sterigmatocystin, penicillin G, emericellamide, aspernidine A, xanthone, austinol, and siderophores are down-regulated by SirA. Aspergillus nidulans WT and SirAd strains were cultured in 200 ml of GMM at 30Â°C for 24, 48, and 72 h, and their total RNA was purified as described above.
