Circadian and light-induced expression of luciferase in Neurospora crassa. Academic Article uri icon


  • We have constructed a plasmid vector for expressing firefly luciferase in Neurospora crassa under control of the light- and clock-regulated ccg-2 (eas) promoter. The sequence of the luciferase gene in the vector has been modified to reflect the N. crassa codon bias. Both light-induced activity and circadian activity are demonstrated. Expression of luciferase in strains carrying mutant frequency alleles shows appropriate period length alterations. These data demonstrate that luciferase is a sensitive reporter of gene expression in N. crassa. Our results also show that the modified luciferase is expressed in Aspergillus nidulans.
