Bryum species generally have shorter laminal cells with short, thick, and rounded stems. [3] All Bryum species exhibit narrowed cells at the margins. Bryum species can be identified through patterns of asexual reproduction , coloration features of the stem and leaf base, and the strength of the leaf border.
Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
Bryum argenteum, the silvergreen bryum moss or silvery thread moss, [1] is a species of moss in the family Bryaceae. It is one of the most common mosses of urban areas and can be easily recognized without a microscope.
In hornworts, the meristem starts at the base where the foot ends, and the division of cells pushes the sporophyte body upwards. In mosses, the meristem is located between the capsule and the top of the stalk (seta), and produces cells downward, elongating the stalk and elevating the capsule.
The leaf cells are elongated at the leaf base and smooth, the top sheet portion extends to approximately square and smooth. The leaf wing cells are clearly differentiated. The spore capsule, at the end of the 7-16 millimeter-long seta is strumose and more or less inclined.
The targeted deletion or alteration of moss genes relies on the integration of a short DNA strand at a defined position in the genome of the host cell. Both ends of this DNA strand are engineered to be identical to this specific gene locus. The DNA construct is then incubated with moss protoplasts in the presence of polyethylene glycol.
Polytrichum commune (also known as common haircap, [2] great golden maidenhair, [2] great goldilocks, [2] common haircap moss, or common hair moss) is a species of moss found in many regions with high humidity and rainfall. The species can be exceptionally tall for a moss with stems often exceeding 30 cm (12 in) and rarely reaching 70 cm (27.5 ...
The GBIF also lists Morinia Cardot, [3] Saitoa, [4] Sebillea M.Bizot, 1974, [5] and Spruceella Müll.Hal., 1900 [6] but with no subfamily details.. Subfamily Timmielloideae (and its two genera of Timmiella and Luisierella) have been transferred to a new family Timmiellaceae, due to molecular phylogenetic analysis in 2014.
