GAMETE EXPRESSED PROTEIN1 ortholog in Marchantia polymorpha is essential for male pronucleus formation in fertilized egg cells

Abstract GAMETE EXPRESSED PROTEIN1 (GEX1) is a gamete nuclear membrane protein essential for nuclear fusion during sexual reproduction in Arabidopsis thaliana. GEX1 orthologs have been identified in several terrestrial plants. The liverwort Marchantia polymorpha, which uses motil...

REAP1/AtSWAP70 integrates RAB5 and ROP signalling during sexual reproduction

Small GTPases of the Ras superfamily are critical regulators of diverse cellular processes. While crosstalk between their signalling pathways has been documented in animals, similar mechanisms remain unexplored in plants, where small GTPases have undergone unique evolutionary div...

ABCG transporters are involved in the accumulation of specialized metabolites in the oil bodies of Marchantia polymorpha.

Bioactive specialized metabolites (SMs) are synthesized and sequestered in specific cellular compartments or organelles as a self-defense strategy against their intrinsic toxicity. Liverwort-specific oil bodies accumulate large amounts of SMs and contribute to chemical defense; h...
