| Gene ID | Name | Evidence / Role | Function (this paper) |
|---|---|---|---|
| Mp5g06600 | MpDDP1 | experimental subject | Characterized as an inositol 1-pyrophosphate phosphatase cleaving 1-InsP7, clustering with AtNUDT17/18/21 and yeast Ddp1. Mutants show only mild growth defects with slightly reduced thallus surface and elevated 1-InsP7 and 1,5-InsP8; double mutants with MpPFA-DSP1 are not viable. |
| Mp3g10950 | MpPFA-DSP1 missing | experimental subject | Characterized as a specific inositol 5-pyrophosphate phosphatase preferring 5-InsP7 over 1,5-InsP8, clustering phylogenetically with Arabidopsis PFA-DSPs and yeast Siw14. Loss-of-function mutants show vertical thallus growth, reduced surface area, more rhizoids, fewer gemma cups, elevated 5-InsP7, and altered cell wall and PSI gene expression. |
| Mp8g06840 | MpVIH | experimental subject | Single PPIP5K gene encoding a bifunctional kinase/phosphatase. Mutants resemble Mppfa-dsp1 with vertical growth, reduced thallus, more rhizoids, fewer gemma cups, lower 1,5-InsP8 and higher 5-InsP7; the Mppfa-dsp1 Mpvip1 double mutant is severely stunted with high nitrate. |
| Mp4g19710 | MpPHO1;H4 missing | experimental tool | Used as a PSI marker gene; decreased in Mppfa-dsp1ge/Mpvip1ge and increased in Mpnudt1ge mutants. |
| Mp2g20620 | MpPHT1;4 missing | experimental tool | Pi transporter used as a PSI marker gene; elevated in Mppfa-dsp1ge and Mpvip1ge mutants. |
| Mp1g27550 | MpSPX | experimental tool | Used as a phosphate-starvation-induced (PSI) marker gene; its transcript decreased in Mppfa-dsp1ge and Mpvip1ge mutants. |
| Mp1g22660 | MpIPMK | sequence background | A PP-InsP biosynthetic enzyme whose transcript was quantified by RNA-seq; no loss-of-function mutant generated. |
| Mp2g24850 | MpITPK1 | sequence background | A PP-InsP biosynthetic enzyme whose transcript was quantified by RNA-seq; no loss-of-function mutant generated. |
