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) were localized to heterochromatic foci in Neurospora nuclei, consistent with prior findings with carboxy-terminal HP1-GFP fusion proteins.
