Extracted Explainers

What the tool is doing

ZGT is described as a novel tobacco gene regulated by the circadian clock and light, with rhythmic expression and rapid light induction.

Source 1DOI

What problem it solves

The paper postulates that ZGT links the central circadian oscillator to rhythmic LHCB1*1 expression.

Source 1DOI

Evidence Snippets

We have identified and characterized a novel tobacco gene, called ZGT (from the Chinese phrase zhong guang tiaokong, or clock and light controlled), that is regulated by the circadian clock and light.

Linked Claims

Claim 1expression patternsupports2001Source 1DOI

ZGT is expressed rhythmically in light/dark cycles and in constant light.

Claim 2expression patternsupports2001Source 1DOI

ZGT transcripts have alternate forms that are differentially expressed in different tissues.

Claim 3functional effectsupports2001Source 1DOI

Constitutive expression of ZGT does not affect LHCB1*1 expression in constant light.

Claim 4functional effectsupports2001Source 1DOI

Constitutive expression of ZGT sustains LHCB1*1 expression in constant darkness where it would normally dampen.

Claim 5functional effectsupports2001Source 1DOI

Overexpression of ZGT increases the sensitivity of the circadian oscillator to brief light pulses.

Claim 6light responsesupports2001Source 1DOI

ZGT expression is induced rapidly by light.

Claim 7mechanistic hypothesissupports2001Source 1DOI

The authors postulate that light- and clock-regulated expression of ZGT acts as a coupling agent between the central circadian oscillator and rhythmic LHCB1*1 expression and may function in plant phototransduction pathways.

Claim 8promoter featuresupports2001Source 1DOI

The ZGT promoter includes a G-box motif and evening element motifs associated with light regulation and circadian control.

Claim 9regulationsupports2001Source 1DOI

ZGT is a novel tobacco gene regulated by the circadian clock and light.
