Project description:Microarray analysis was used to compare different developmental stages of the filamentous fungus Aspergillus nidulans. Cells were grown for various times and comparisons made between: 1. Isolated conidia (0 hours) and isotropically expanding cells (3 hours). 2. Isotropically expanding cells (3 hours) and polarly extending cells (5 hours). 3. Undifferentiated vegetative hyphae (18 hours) and synchronously conidiating cultures (42 hours). Keywords: Developmental stage comparison

Isotropically expanding cells (3 hours) and polarly extending cells (5 hours). 3. Undifferentiated vegetative hyphae (18 hours) and synchronously conidiating cultures (42 hours). A total of 4 hybridizations were performed for each microarray experiment described in the summary. The following replicates were carried out: 1. Two biological replicates were performed using cultures grown in parallel. 2. Two Technical ‘dye swap’ replicates were carried out for each biological replicate.
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.
