Bryum is a genus of mosses in the family Bryaceae.It was considered the largest genus of mosses, in terms of the number of species (over 1000), until it was split into three separate genera in a 2005 publication. [1]
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.
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 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.
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.
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 costa are long, sometimes excurrent, and lack an adaxial pad of cells. They are narrow distally, with hexagonal distal laminal cells measuring 10-15 μm wide. These cells bear many papillae. The moss is autoicous, and its sporophytes are exerted. Its seta measure 0.6–1.5 cm (0.24–0.59 in). Its erect and cylindrical capsules are ...
Bryology (from Greek bryon, a moss, a liverwort) is the branch of botany concerned with the scientific study of bryophytes (mosses, liverworts, and hornworts). Bryologists are people who have an active interest in observing, recording, classifying or researching bryophytes. [1]
