# Marchantia polymorpha standard reference genome ver. 6.1 revision2 (MpTak_v6.1r2) ## Overview 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. ## Citation Please site the following paper. Chromatin organization in early land plants reveals an ancestral association between H3K27me3, transposons, and constitutive heterochromatin (Montgomery, Tanizawa, Galic, et al. [Current Biology, 30(4) P573-588, 2020](https://www.cell.com/current-biology/fulltext/S0960-9822(19)31610-0). The paper describing Tak2 and the standard genome is also under preparation. ## Statistics - __Number of chromosomal sequences__: 10 (8 autosomes, U and V sex chromosomes) + 29 unplaced scaffolds - __Total length__: 220,358,409 bp (chromosomes) and 488,250 bp (unplaced scaffolds) - __Number of protein coding genes__: 18042 - __NUmber of transcripts (including splicing variants)__: 22674 ## Change Log The first version (MpTak_v6.1r1) was constructed based on MpTak1_v5.1 and the U chromosome sequence from Tak-2. The gene annotation was based on MpTak1_v5.1r2. As of revision 2 (MpTak_v6.1r2), some of the unplaced scaffolds have been removed/updated (repetitive or redundant sequences), and some of the spurious gene models have been removed. __The following
