We report the draft genome sequence of the model moss Physcomitrella patens and compare its features with those of flowering plants, from which it is separated by more than 400 million years, and unicellular aquatic algae. This comparison reveals genomic changes concomitant with the evolutionary movement to land, including a general increase in gene family complexity; loss of genes associated with aquatic environments (e.g., flagellar arms); acquisition of genes for tolerating terrestrial… Expand

Studies of Physcomitrella patens reveal that ethylene-mediated submergence responses arose relatively early in land-plant evolution.
TLDR
It is shown that extant bryophytes exhibit submergence-induced developmental plasticity, suggesting that submergence responses evolved relatively early in the evolution of land plants. Expand
Physcomitrella patens: A Model Bryophyte
TLDR
Genomic comparisons and other studies suggest that there are many similarities in the ways in which mosses and angiosperms use environmental cues to develop, indicating conserved evolution; however, mosses also possess some unique sequences which might present novel gene functions. Expand
The Genome of the Model Moss Physcomitrella patens
TLDR
The duplicated parts of the moss genome, like the paralogous genes that were retained after ancestral, large-scale to whole-genome duplication events and can be used to gain insights into the evolutionary history of Physcomitrella. Expand

TLDR
The draft genome sequence of the filamentous terrestrial alga Klebsormidium flaccidum is reported to elucidate the early transition step from aquatic algae to land plants and suggests that, during evolution, this alga acquired the fundamental machinery required for adaptation to terrestrial environments.

Physcomitrella patens: mosses enter the genomic age.
TLDR
Transgenic studies show that the regulatory factors ABSCISIC ACID INSENSITIVE3 (ABI3) and LEAFY (LFY) have molecular functions that are conserved between moss and angiosperms, in spite of the fact that they function in non-homologous tissues. Expand
An ancient genome duplication contributed to the abundance of metabolic genes in the moss Physcomitrella patens
TLDR
Based on a large collection of EST sequences, evidence is provided that the haploid moss Physcomitrella patens is a paleopolyploid as well and metabolic genes seem to have been retained in excess following the genome duplication in P. patens. Expand
The organization of Physcomitrella patens RAD51 genes is unique among eukaryotic organisms
TLDR
The presence of duplicated intronless RAD51 genes is unique among eukaryotes, and studies of further members of this lineage are needed to determine whether this feature may be typical of lower plants. Expand
The Ancestral Developmental Tool Kit of Land Plants
TLDR
The genome of the earliest embryophytes encoded homologues of many of the important developmental genes that have been identified in model angiosperm taxa, but the roles of these were probably somewhat different than the roles attributed to them in Arabidopsis and maize. Expand
A dehydrin gene in Physcomitrella patens is required for salt and osmotic stress tolerance.
TLDR
Direct genetic evidence in any plant species for a DHN exerting a protective role during cellular dehydration allowing recovery when returned to optimal growth conditions is provided. Expand
The Genome of Black Cottonwood, Populus trichocarpa (Torr. & Gray)
TLDR
Analyzing the draft genome of the black cottonwood tree, Populus trichocarpa, revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. Expand
Physcomitrella patens is highly tolerant against drought, salt and osmotic stress
TLDR
A set of genes are identified that encode proteins exerting their function in maintaining the integrity of the plant cell as well as proteins that are known to be members of signaling networks that will serve as molecular markers and potential targets for future functional analyses. Expand
Desiccation Tolerance in Bryophytes: A Reflection of the Primitive Strategy for Plant Survival in Dehydrating Habitats?1
TLDR
A new phylogenetic analysis suggests that the basic mechanisms of tolerance seen in modern day bryophytes have changed little from the earliest manifestations of desiccation tolerance in land plants, and vegetative desiccence tolerance in the early land plants may have evolved from a mechanism present first in spores.

PlanTAPDB, a Phylogeny-Based Resource of Plant Transcription-Associated Proteins1[C][W][OA]
TLDR
A substantial set of TAPs that are focused on, but not limited to, land plants are determined using PSI-BLAST searches and subsequent filtering and clustering steps, and initial analyses of selected gene families revealed that PlanTAPDB can easily be exerted for knowledge discovery. Expand
The mechanism of gene targeting in Physcomitrella patens: homologous recombination, concatenation and multiple integration
TLDR
Molecular analysis of TI at a single locus reinforces the view that HR is the major pathway by which transforming DNA is integrated in Physcomitrella, as a consequence of concatenation of the transforming DNA prior to integration. Expand
