Joint Genome Institute (JGI) has sequenced the genome of Physcomitrella patens
to about 8.6x coverage. Sequencing was done using whole genome shotgun (WGS) strategy and the genome was assembled using the JAZZ genome assembly system. None of the contigs have been placed on chromosomes in this first version of the WGS assembly.
The P. patens genome is approximately 480 Mb organized as 27 pairs of chromosomes. The genome assembly consists of 2106 scaffolds, 1443 of which are annotated. The sequence contains 35,938 predicted and annotated gene models. Details regarding sequencing, annotation, and analysis of the genome can be found at Rensing et al. Science 319(5859):245-50, 2007.
The NCBI Map Viewer provides graphical displays of features on the Physcomitrella patens genome sequence assembly. Some of the map features that can be seen along the sequence include NCBI contigs (the Contig map), the WGS sequences (the Component map), and the location of aligned transcripts from P. patens (rnaPpa) and Arabidopsis thaliana (rnaAt). The genes on sequence map include both known genes and putative genes based on JGI submission. The complete set of Gnomon predicted gene models can be viewed on the ab initio map.
