This web site currently contains three versions of the Marchantia reference genome, JGI 3.1, MpTak1v5.1 (M. polymorpha subsp. ruderalis), and MpTak1_v6.1 (Standard genome for analytical use. Tak-1 autosome + Tak-1 V-chr + Tak-2 U-chr), as well as genomes from subsp. polymorpha (MppBR5) and subsp. montivagans (MpmSA2).
The data provided in this web site is freely available for academic purposes. Please cite our paper if you use the data obtained from the web site.
High-quality chromosome-level reference genomes asembled from PacBio HiFi sequencing reads.
The gene annotation have been lifted over from MpTak_v6.1 with some manual curation.
MpTak1_v7.1: chr1-8 and sex chromosome V derived from the male Tak-1 strain.
MpTak2_v7.1: chr1-8 and sex chromosome U derived from the female Tak-2 strain.
See README for more details.
Standard reference genome for analytical use.
Consists of a combination of chr1-8,V from male Tak-1 and chrU from female Tak-2
See README for more details.
Standard reference genome for analytical use. Created by combining the male Tak-1 genome (MpTak1v5.1) and the female Tak-2 U-chr sequence.
Some of the uplaced scaffolds of MpTak1_v5.1 were removed (bacterial contamination, organellar sequences) and updated.
Assembly and annotation version
The latest annotation version is Revision 2 (MpTak_v6.1r2, 20230601).

The paper describing Tak2 and the standard genome is also under preparation.
Chromosome-level genome assembly of the male Tak-1 strain obtained from PacBio long-read sequencing and Hi-C scaffolding. Consists of 9 chromosomal sequences and 435 unplaced scaffolds.
Assembly and annotation version
The latest annotation version is Revision 2 (MpTak1_v5.1r2).
Changes from Revision1 to Revisio2
The Genome Annotation Jamboree was held during Marchantia Workshop 2019 (Sendai, Japan) to improve gene annotation.
We have incorporated the improved gene models curated by the participitants to create the Revision2 annotation. We would like to thank all the participitants in the Jamboree.
This update also includes newly-identified gene models, removal of spurious gene models, merging of wrongly-separated gene models.
Please note that the genome sequences of revision2 are the same as those of revision1. (Only annotations have been updated.)
