Expression and Visualization of Red Fluorescent Protein (RFP) in Neurospora crassa

Abstract

We report the expression of Discosoma red fluorescent protein (RFP) and RFP fusion proteins in Neurospora crassa. RFP was expressed under the control of the Neurospora ccg-1 promoter in transformants with single copies integrated at the his-3 locus by gene targeting. Because this RFP gene, tdimer2(12), contains a 677 bp direct tandem repeat of dsRed, RFP constructs underwent RIP at high frequency in rid strains. Fusion proteins of RFP to the amino terminus of Neurospora heterochromatin protein 1 (HP1) +
