Evidence Snippets

Here we report on the role of two other photoreceptors in U. maydis, namely White collar 1 (Wco1) and Phytochrome 1 (Phy1).

Linked Claims

Claim 1biochemical propertysupports2021Source 1DOI PubMed

Phy1 binds biliverdin as a chromophore.

Claim 2coregulationsupports2021Source 1DOI PubMed

Most red and far-red light-controlled genes depend on both Phy1 and Wco1, indicating partial coregulation of gene expression by the two photoreceptors.

Claim 3gene regulation rolesupports2021Source 1DOI PubMed

Ustilago maydis responds to red and far-red light, but fewer genes are controlled by red or far-red light than by blue light.

Claim 4interaction inferencesupports2021Source 1DOI PubMed

The localization data provide no hint that Wco1 and Phy1 directly interact or operate within the same complex.

Claim 5noveltysupports2021Source 1DOI PubMed

This study is the first report of functional characterization and coaction of White collar 1 and phytochrome orthologs in basidiomycetes.

Claim 6photocycle activitysupports2021Source 1DOI PubMed

Both Wco1 and Phy1 undergo a photocycle in vitro.

Claim 7subcellular localizationsupports2021Source 1DOI PubMed

GFP-fused Wco1 is preferentially localized in the nucleus, whereas Phy1 is localized in the cytosol.
