Functional expression and cellular localization of cercosporin-resistance proteins fused with the GFP in Cercospora nicotianae

Chung, K.-R., Ehrenshaft, M., & Daub, M. E. (2002, June 1). Current Genetics.

By: K. Chung n, M. Ehrenshaft n & M. Daub n

author keywords: photosensitizer; singlet oxygen; fungi; pyridoxine
MeSH headings : Ascomycota / drug effects; Ascomycota / genetics; Ascomycota / metabolism; Base Sequence; Blotting, Western; DNA Primers; Fungal Proteins / genetics; Fungal Proteins / metabolism; Green Fluorescent Proteins; Luminescent Proteins / metabolism; Microscopy, Confocal; Perylene / analogs & derivatives; Perylene / pharmacology; Recombinant Fusion Proteins / genetics; Recombinant Fusion Proteins / metabolism; Transformation, Genetic
topics (OpenAlex): Fungal and yeast genetics research; Mycotoxins in Agriculture and Food; Bacterial Genetics and Biotechnology
TL;DR: Transformation of these constructs into strains mutant in these respective genes resulted in green-fluorescent transformants complemented for the mutant phenotype, a result inconsistent with microscopic observation and computer sequence analysis, which suggests that CRG1 is a membrane protein.
