The moss Physcomitrella patens is a model organism for studying the evolution of land plants. As a Bryophyte this organism sits midway along the evolutionary path between unicellular aquatic algae and flowering land plants.

Physcomitrella patens has a very efficient mechanism of homologous recombination which can be used to create targeted genetic modifications. It also shows alternation of generations, with the haploid phase of the life-cycle being dominant. These characteristics make it an excellent experimental material. It is used to examine the key genetic changes involved in adaptation to water stress and temperature variation, associated with life on land, and the loss of flagellae, associated with aquatic life.

The reference proteome for Physcomitrella patens is derived from the genome published in 2008 ( ). The genome has a haploid chromosome number of 27 containing nearly 500 Mb, with 35,000 protein-coding genes. Further details of the genome assembly are available at the 'Physcomitrella patens resource' (
