Marchantia polymorpha Assembly and Gene Annotation

Marchantia polymorpha is a liverwort from a basal land plant lineage. It is almost cosmopolitan and can be found around human habitats in temperate regions. It is a model plant which has been studied for nearly 200 years. It has a short life cycle, it’s easy to propagate, cross and transform and has a small haploid genome. Its life cycle alternates between multicellular haploid gametophyte and diploid sporophyte generations. Compared to other land plants exhibits low genetic redundancy.

The nuclear and organellar genomes of M. polymorpha subspecies ruderalis were sequenced using a whole-genome shotgun sequencing strategy with 27x mean coverage. A a single clonal female derived from backcross 4 between a male Tak-1 line and a female Tak-2 line, whose X chromosome was introgressed into a largely Tak-1 autosomal background. Nuclear genome v 3.1 assembly consists of 2,957 scaffolds (4,454 contigs) covering 225.8 Mb.
