Gene ID	Name	Evidence / Role	Function (this paper)
Mp8g13070	MpABCG1	experimental subject	An oil-body-localized ABC transporter studied via loss-of-function mutants. Mpabcg1 mutants showed reduced sesquiterpene (thujopsene, chamigrene, himachalane) and bisbibenzyl (marchantins C and A) accumulation and fewer BODIPY-stained oil bodies, indicating MpABCG1 is involved in sequestering specialized metabolites in oil bodies.
Mp2g14210	MpABCG36	experimental subject	An oil-body-localized ABC transporter studied via loss-of-function mutants. Mpabcg36 mutants showed reduced sesquiterpene accumulation (but not bisbibenzyls), implicating MpABCG36 in accumulation of specialized metabolites/precursors in oil bodies.
Mp4g20670	MpSYP12B	experimental tool	Used as an mCitrine-fused oil body membrane marker to quantify oil bodies in mutant versus wild-type lines.
