Gene ID Name Evidence / Role Function (this paper)
Mp4g20380 MpPP2C_E experimental subject Identified as the single M. polymorpha ortholog of Arabidopsis clade L PP2C19. CRISPR/Cas9 knockout lines (Mppp2c19ge) failed to show the chloroplast accumulation response under weak blue light while retaining normal dark positioning and the avoidance response, indicating MpPP2C19 is specifically required for the accumulation response and that this function is evolutionarily conserved among land plants.
Mp5g03810 MpPHOT experimental background M. polymorpha phototropin; a previously described knockout line (Mpphotko) referenced in the Marchantia chloroplast photorelocation experiments.
