Gene ID	Name	Evidence / Role	Function (this paper)
Mp2g24850	MpITPK1	experimental subject	Overexpression in Marchantia raised 5-InsP7 and InsP8 and weakened the Pi-starvation response (fewer/shorter rhizoids, lower PSI gene expression); MpITPK1 also complemented the Arabidopsis atitpk1-2 mutant. Identified as a kinase controlling Pi-responsive PP-InsP signaling.
Mp7g19050	MpPHO1a missing	experimental subject	Knockout lines over-accumulated Pi in rhizoids relative to thallus and showed abnormal InsP/PP-InsP levels (notably elevated 1,5-InsP8) with PSI gene expression altered more in thallus than rhizoids. Acts as a Pi exporter critical for tissue Pi distribution and homeostasis.
Mp1g28440	MpMATE1	experimental tool	PSI marker gene used alongside MpSPX to read out reduced Pi-starvation response in transgenic lines.
Mp1g27550	MpSPX	experimental tool	PSI marker gene whose lower expression reports a dampened Pi-starvation response in MpITPK1 overexpression lines.
