Project description:Light is a major environmental signal regulating many different biological processes. In Aspergillus nidulans light controls asexual and sexual development as well as the production of secondary metabolites. In order to get a global view of genes regulated during asexual development and of genes involved in other light-regulated biological processes, a genome-wide approach was undertaken. Total RNA was isolated from surface-grown, developmentally competent mycelia of the wild-type strain FGSC4 exposed to white light (11 W/m2) for 30 minutes or grown in the dark, labelled, and hybridized to a spotted microarray of A. nidulans.
