A gain-of-function T-DNA insertion mutant of Marchantia polymorpha hyper-accumulates flavonoid riccionidin A.
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.
期刊介绍：
Plant Biotechnology is an international, open-access, and online journal, published every three months by the Japanese Society for Plant Biotechnology. The journal, first published in 1984 as the predecessor journal, “Plant Tissue Culture Letters” and became its present form in 1997 when the society name was renamed to Japanese Society for Plant Cell and Molecular Biology, publishes findings in the areas from basic- to application research of plant biotechnology. The aim of Plant Biotechnology is to publish original and high-impact papers, in the most rapid turnaround time for reviewing, on the plant biotechnology including tissue culture, production of specialized metabolites, transgenic technology, and genome editing technology, and also on the related research fields including molecular biology, cell biology, genetics, plant breeding, plant physiology and biochemistry, metabolic engineering, synthetic biology, and bioinformatics.
