An antisense RNA expression vector for Neurospora crassa

Natural Antisense Transcripts and Long Non-Coding RNA in Neurospora crassa

The prevalence of long non-coding RNAs (lncRNA) and natural antisense transcripts (NATs) has been reported in a variety of organisms. While a consensus has yet to be reached on their global importance, an increasing number of examples have been shown to be functional, regulating gene expression at the transcriptional and post-transcriptional level. Here, we use RNA sequencing data from the ABI ...

Activator-independent gene expression in Neurospora crassa.

A transgenic position effect that causes activator-independent gene expression has been described previously for three Neurospora crassa phosphate-repressible genes. We report analogous findings for two additional positively regulated genes, qa-2+ and ars-1+, indicating that such position effects are not limited to genes involved in phosphorus metabolism. In addition, we have characterized a nu...

Biotransformation of Hydrocortisone by Neurospora crassa

The ability of Neurospora crassa FGSC 4335 in the biotransformation of hydrocortisone was investigated. The microorganism produced two major metabolites after incubation with the substrate for seven days. Each microbial product was purified chromatographically and identified on the basis of spectral data. The products were identified as 11?,17?,20?,21-tetrahydroxypregn-4-en-3-one (II) and 11?-h...

Light-Inducible System for Tunable Protein Expression in Neurospora crassa

Filamentous fungi are important model systems for understanding eukaryotic cellular processes, including the study of protein expression. A salient feature of fungi is the ability of the protein-processing machinery to perform all of the extensive posttranslational modifications needed in the complex world of eukaryotic organisms, making them great hosts for production of eukaryotic proteins. I...
