Open access · cc by · source: Europe PMC
Neurospora photoreceptors WC-1, WC-2 and VVD influence cellulase expression; light-modulated cellulase regulation is conserved in filamentous fungi.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Multiple empirical papers in this library examine circadian biology with mechanistic biological findings.
Evidence for the claim as stated.
WC-1, WC-2 and VVD affect cellulase gene expression; light modulation of cellulases appears conserved, likely advantageous in nature.
Evidence for the claim as stated.
Systems and scales differ across circadian biology studies (species, tissues, methods), so mechanisms should not be over-generalised.

Does light control fungal cellulase genes?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Which photoreceptors influence cellulase expression?
photoreceptors WC-1, WC-2 and VVD influence cellulase gene expression.
Is light-modulated cellulase expression unique?
light-modulated expression of cellulolytic enzymes is a conserved phenomenon, most probably providing an evolutionary advantage to filamentous fungi in their natural habitat.
Key findings
WC-1, WC-2 and VVD affect cellulase gene expression; light modulation of cellulases appears conserved, likely advantageous in nature.
Methodology
Profiled cellulase-related transcription in photoreceptor mutants and compared light effects on cellulolytic enzyme expression.
Limitations
Does not engineer industrial cellulase strains for bioreactors.
