Mp7g11720 MpDCL4 experimental subject Upregulated upon TMV infection. Proposed as the main antiviral DCL in Marchantia given the absence of a DCL2 gene. TMV-derived vsRNAs were enriched in 21-nt fragments consistent with DCL4-mediated processing.
Mp6g06230 MpJAZ experimental subject Mpjaz-1 KO plants (constitutively active jasmonate signaling) used for transcriptome comparison with TMV-infected plants; 238 genes downregulated in both, revealing overlap between jasmonate and antiviral responses.
Mp6g02620 MpNAC7 experimental subject Ortholog of Arabidopsis ATAF2; interacts with the helicase domain and full-length TMV p126 in yeast and in planta. Expression induced by TMV infection, wounding, dn-OPDA and SA. Transient expression in Nicotiana abrogates local and systemic TMV infection.
Mp6g05010 MpGDI2 missing sequence comparator Marchantia ortholog of Arabidopsis GDI2, a TMV p126-associated host factor; tested by Y2H but interaction not confirmed.
Mp7g09160 MpSERK sequence comparator Marchantia ortholog of Arabidopsis PRR co-receptor SERK1/BAK1.
Mp3g00660 MpTOM1 missing sequence comparator Marchantia ortholog of Arabidopsis TOM1, a TMV p126-associated host factor; tested by Y2H but interaction not confirmed.
Mp6g11010 MpACTIN7 experimental tool Used as the housekeeping reference gene for normalizing RT-qPCR expression (2^-DeltaCt method).
Mp8g08610 MpAGO9 experimental background Suppressed upon TMV infection; reported among RdDM/silencing genes.
Mp6g09830
MpDCL1b paper
MpDCL3 nomenclature
 experimental background Upregulated upon TMV infection (non-canonical DCL); reported among altered RNA-silencing genes.
Mp1g02840
MpDCL3 paper
MpDCL1a nomenclature
 experimental background Suppressed upon TMV infection (RdDM-associated DCL); reported in the silencing-gene expression analysis.
Mp2g07720 MpNAC1 experimental background Senescence marker gene induced upon TMV infection.
Mp6g00230 MpNRPE1b experimental background Suppressed upon TMV infection; reported among RdDM pathway genes.
Mp1g17090 MpNYE1 missing experimental background Senescence marker gene induced upon TMV infection.
Mp5g19050 MpR2R3-MYB14 experimental background Senescence marker gene induced upon TMV infection.
Mp8g14970 MpRDR5/6-2 experimental background Upregulated upon TMV infection, reported alongside other RNA-silencing pathway genes.
Mp3g17660 MpWRKY7 experimental background Senescence marker gene induced upon TMV infection.
