| Gene ID | Name | Evidence / Role | Function (this paper) |
|---|---|---|---|
| Mp5g12010 | MpCOP1 | experimental subject | E3 ubiquitin ligase; Mpcop1 mutants show a strong constitutive photomorphogenesis phenotype. COP1 function is much more independent of SPA in Marchantia than in Arabidopsis, and MpHY5 functions antagonistically to MpCOP1. |
| Mp1g16800 | MpHY5 paper
MpBZIP1 nomenclature |
experimental subject | Transcriptional regulator that functions antagonistically to MpCOP1, similar to Arabidopsis HY5/HYH, but with a more limited role in UV-B-mediated gene expression changes in Marchantia. |
| Mp2g18040 | MpRUP1 paper
MpRUP nomenclature |
experimental subject | WD40-repeat protein, a key component of M. polymorpha UV-B signaling studied as part of the conserved core UVR8 photocycle. |
| — | MpSPA missing | experimental subject | SPA component of the COP1/SPA complex; Mpspa mutants develop only a very weak constitutive photomorphogenesis phenotype but show enhanced UV-B acclimation and UV stress tolerance, indicating MpSPA is a negative regulator of MpUVR8 signaling. |
| Mp2g11590 | MpUVR8 | experimental subject | UV-B photoreceptor of M. polymorpha; the paper shows the core UVR8 photocycle is well conserved. MpSPA acts as a negative regulator of MpUVR8 signaling, with Mpspa showing enhanced UV-B acclimation and UV stress tolerance. |
