BACKGROUND Bryophytes represent a very diverse group of non-vascular plants such as mosses, liverworts and hornworts and the oldest extant lineage of land plants. Determination of endogenous phytohormone profiles in bryophytes can provide substantial information about early land plant evolution. In this study, we screened thirty bryophyte species including six liverworts and twenty-four mosses ...

Bryophytes mark a pivotal step in land plant evolution, and their significance in the regulation of ecosystems and the conservation of biodiversity is becoming increasingly acknowledged. This introductory textbook assumes no prior knowledge of bryophyte biology, making it ideal for advanced undergraduate and graduate students, as well as for amateur botanists. The authors expertly summarize the...

Since the availability of first complete DNA sequence of chloroplast genome of Marchantia polymorpha several studies to determine the structure and organization of chloroplast genomes of various plant groups have been made. However the lineage sampling of bryophytes are poorly represented in complete chloroplast genome sequences (only three liverworts, two mosses and one hornwort). This review ...

The pre-Cenozoic bryophyte fossil record is significantly sparser than that of vascular plants or Cenozoic bryophytes. This situation has been traditionally attributed to a hypothesized low preservation potential of the plants. However, instances of excellent pre-Cenozoic bryophyte preservation and the results of experiments simulating fossilization contradict this traditional interpretation, s...

Bryophytes are a group of plants generally with small sizes and spores as generative reproduction. There three main groups Bryophytes: liverworts or hepatics (Marchantiophyta), mosses (Bryophyta), hornworts (Anthocerophyta). They found in almost all ecosystems. Ecopark Cibinong Science Center-Botanical Garden (CSC-BG) is lowland ecosystem protection area located industrial cities. The bryophyte...

Bryophytes are small, photosynthetic plants, capable of growing on variety habitats, so pioneer ecological succession. In Nepal bryophytes have been studied floristically in different parts the country, but impact disturbance floristic composition was lacking. Therefore, present study aimed to determine especially disturbed habitat generated by recently established Cable Car facility Chandragir...

BACKGROUND Recent decades have seen a major surge in the study of interspecific variation in functional traits in comparative plant ecology, as a tool to understanding and predicting ecosystem functions and their responses to environmental change. However, this research has been biased almost exclusively towards vascular plants. Very little is known about the role and applicability of functiona...

Bryophytes and angiosperms exhibit similar intercontinental disjunct distributions that have traditionally been explained by continental drift. Such disjunct distributions are, however, typically observed at the species level in bryophytes, whereas they occur at much higher taxonomic level in angiosperms. The corollary of this observation is that morphological evolution in bryophytes is exceedi...

Bryophytes are a non-monophyletic group of three major lineages (liverworts, hornworts, and mosses) that descend from the earliest branching events in the phylogeny of land plants. We postulate that desiccation tolerance is a primitive trait, thus mechanisms by which the first land plants achieved tolerance may be reflected in how extant desiccation-tolerant bryophytes survive drying. Evidence ...
