We show that the moss sex chromosomes evolved over 300 million years ago and expanded via two chromosomal fusions. Ceratodon purpureus (Ditrichaceae) Description This striking moss likes to grow on recently burned ground. Commonly known as fire moss, Ceratodon purpureus has been used as a model system to discover novel genes because it can tolerate induced mutations. The genome of C. purpureus is estimated to be smaller than that of P. patens (∼360 Mbs vs 514 Mbs; Voglmayr, 2000 ), and the chromosome number is approximately half as well (n = 13 vs n = 27; Crum & Anderson, 1981 ). The mature purple stalks have oblong purple capsules, some still with straw-colored protective sheaths (calyptra) covering a lighter purple operculum (B). Unreviewed (356) TrEMBL. Info; Download; HELP! Here we test for degeneration in the bryophyte UV sex chromosome system through genomic comparisons with new female and male chromosome-scale reference genomes of the moss Ceratodon purpureus. Thornton LE(1), Keren N, Ohad I, Pakrasi HB. conicus + Stems usually greater than 1 cm; distal leaves more open, usually crisped when dry, not forming a comal tuft, spreading when wet, 1.2-1.8 mm, margins often toothed; costa percurrent to slightly excurrent : 2c Ceratodon purpureus subsp. Physcomitrella patens and Ceratodon purpureus, mosses as model organisms in photosynthesis studies. Redshank Moss - Ceratodon purpureus. Ceratodon purpureus, commonly know as the fire moss or the purple horned moss, is a short weed like moss that forms dense often-forked tuffs or cushions.The peristome teeth, which aid in spore dispersal, are also forked. It is one of the most common cosmopolitan mosses, occurring on a wide variety of substrata, particularly those that are well-drained and acidic. Habitat. Thank you. Description. . The fire moss also thrives in a variety of habitats from urban environments to metal contaminated soils such as near mining operations. This very variable species forms cushions or patches which vary from yellow to mid-green through red to purplish-brown, with shoots to 3 cm.

Ceratodon purpureus is typically found growing in areas that are frequently disturbed or on soils that are sterile. Taxonomy - Ceratodon purpureus (Fire moss) (Dicranum purpureum) (SPECIES) ))) Map to UniProtKB (360) Reviewed (4) Swiss-Prot. Author information: (1)Department of Biology, Washington University, St. Louis, MO 63130, USA. Proposal Name: The moss Ceratodon purpureus (Proposal ID: 156 / 300506) Proposal PI: Stuart McDaniel . Ceratodon purpureus is the second moss, after the laboratory model Physcomitrella patens, chosen for whole genome sequencing. The most abundant of the species, C. purpureus, has a worldwide distribution and is conspicuous because of its purple capsule (spore case), especially when growing on bare, acidic soil or burned areas. Other articles where Ceratodon purpureus is discussed: horn-tooth moss: …any plant of the genus Ceratodon (about 5 species) in the subclass Bryidae. Format. 2b Ceratodon purpureus subsp.
