Gene ID Name Evidence / Role Function (this paper)
Mp1g12750 MpARF1 experimental subject microRNA knockdown line (amiR-MpARF1) reduces auxin sensitivity and attenuates the amplitude of rhythmic waving without altering its period.
Mp4g21220 MpLUX experimental subject Two independent mutant alleles (Mpluxge-9, Mpluxge-19) show arrhythmic phenotypes with dampened rhythm and elevated MpPRR; free IAA oscillations are lost in the mutant.
Mp2g16560 MpPRR experimental subject Knockout mutant (Mpprrko) loses rhythmic thallus movement in continuous light and shows arrhythmic clock gene expression. Forms part of a core transcriptional feedback loop; repressed by MpTOC1 and activated by MpRVE.
Mp2g14310 MpRVE experimental subject Knockout mutant (Mprveko) shows an arrhythmic phenotype. Acts as a transcriptional activator of MpPRR and other clock genes within the core feedback loop.
Mp5g14320 MpTAA experimental subject Encodes the first-step auxin biosynthesis enzyme; qRT-PCR shows a circadian expression pattern in wild-type that is disrupted in clock mutants, linking the clock to auxin output.
Mp3g09460 MpTOC1 experimental subject Knockout mutant (Mptoc1ko) loses rhythmic movement in continuous light. Acts as a repressor of MpPRR and is itself repressed by MpRVE, forming the core feedback loop.
Mp8g08780 MpYUC2 experimental subject Auxin biosynthesis enzyme; qRT-PCR detected no rhythmic expression in constant light, while overexpression produces an epinastic growth phenotype.
Mp3g19510 MpSHI experimental tool Apical-notch-active promoter used to drive iaaL expression (MpSHIpro:iaaL) to deplete auxin locally.
Mp1g10870 MpELF3 sequence background Reported as a homolog present in the M. polymorpha genome; not experimentally characterized here.
Mp1g16510 MpELF4 sequence background Reported as a homolog present in the M. polymorpha genome; not experimentally characterized here.
Mp1g13750 MpGI sequence background Reported as a homolog in the M. polymorpha genome, noted as a large protein of unclear biochemical function; not experimentally characterized here.
MpZTL missing sequence background Reported as a homolog present in the M. polymorpha genome; not experimentally characterized here.
