A gain-of-function T-DNA insertion mutant of Marchantia polymorpha hyper-accumulates flavonoid riccionidin A.

ABSTRACT: Marchantia polymorpha is a model liverwort for which many molecular biological techniques are now available. We previously developed the S-AgarTrap method for easy genetic transformation of M. polymorpha using spores. In this study, we report production of a T-DNA insertion mutant library (approx. 10,000 lines) for M. polymorpha using the S-AgarTrap method. We further isolate and characterize a gain-of-function mutant that hyper-accumulates the flavonoid riccionidin A. The present study demonstrates that the S-AgarTrap-mediated production of a T-DNA insertion mutant library is a powerful tool for molecular biology in M. polymorpha.
