Abstract
RNA silencing represents a powerful approach to test gene function, especially when essential genes with a lethal deletion phenotype are investigated. This phenomenon can be triggered by different systems. One of them gives rise to the formation of double-stranded RNA molecules by means of plasmid pJL43-RNAi (J Microbiol Methods 75:209–218, 2008), which has proven its efficiency in the beta-lactam producing fungi, Penicillium chrysogenum and Acremonium chrysogenum.
