Gene ID	Name	Evidence / Role	Function (this paper)
Mp1g12750	MpARF1	experimental subject	One of three Marchantia auxin response factors; transient transactivation assays showed distinct transcriptional activity, and MpARF proteins interacted with MpIAA with differing affinities, defining a minimal auxin-responsive transcription system.
Mp4g11820	MpARF2	experimental subject	One of three Marchantia auxin response factors; characterized alongside MpARF1/MpARF3 by transactivation assays as part of the minimal ARF set governing auxin-mediated transcription.
Mp1g07070	MpARF3	experimental subject	One of three Marchantia auxin response factors; transactivation assays showed activity consistent with its phylogenetic class within the minimal auxin-signaling component set.
Mp6g05000	MpIAA	experimental subject	The single Marchantia AUX/IAA; a stabilized degron-mutant allele (MpIAA mDII) conferred auxin resistance, and DEX-inducible repression caused severe developmental defects, demonstrating its central role in auxin-mediated transcription.
Mp6g02750	MpTIR1	sequence subject	Identified by BLAST as the single Marchantia TIR1/AFB auxin receptor (~54% identity to Arabidopsis TIR1). Named as a component of the minimal auxin module but not functionally assayed in this study.
Mp3g23400	MpEF1	experimental tool	Used as a molecular tool: the constitutive proMpEF1alpha promoter drove the modified auxin-signaling constructs (e.g. proMpEF1α:MpIAA mDII) in transgenic Marchantia, rather than being a subject of study here.
Mp2g26590	MpCOI1	sequence background	Jasmonate (COI1) receptor homolog identified in the M. polymorpha genome during the search for hormone-signaling components; reported on sequence/phylogenetic grounds only, not functionally studied here.
Mp7g17410	MpTPL	citation background	TOPLESS (TPL) co-repressor homolog cited as the likely partner recruited by the MpIAA domain-I (EAR-like) motif in auxin-mediated transcriptional repression; not directly assayed in this paper.
