A Proposal to Collect Bryophytes (mosses, Liverworts, and Hornworts) from the Jasper Ridge Biological Preserve
نویسنده
چکیده
Bryophytes are the first lands plants that include three distinct lineages: mosses, liverworts, and hornworts. They differ primarily from the flowering plants by lacking roots, flowers, seeds, and a defined system of tissues for transporting fluids throughout the plant. Bryophytes reproduce not by seeds, but rather, single-celled spores. Many bryophytes can also form new plants by vegetative means.

Chloroplast Genome Analysis to Detect Transition Link between Bryophytes and Pteridophytes: A Bioinformatics Approach
Bryophytes (mosses, liverworts and hornworts) are the most basal lineages among extant land plants. However, there is controversy regarding their monophyletic or paraphyletic origin. Moreover, the most basal group of bryophytes also remains questionable. Due to this it is a matter of debate which lineage of bryophytes acts as transition link between bryophytes and pteridophytes. In order to res...
متن کاملPhylogeny and diversification of bryophytes.
The bryophytes comprise three phyla of embryophytes that are well established to occupy the first nodes among extant lineages in the land-plant tree of life. The three bryophyte groups (hornworts, liverworts, mosses) may not form a monophyletic clade, but they share life history features including dominant free-living gametophytes and matrotrophic monosporangiate sporophytes. Because of their u...

متن کاملPhytohormone Profiling across the Bryophytes
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 ...
متن کاملThe Interrelationships of Land Plants and the Nature of the Ancestral Embryophyte
The evolutionary emergence of land plant body plans transformed the planet. However, our understanding of this formative episode is mired in the uncertainty associated with the phylogenetic relationships among bryophytes (hornworts, liverworts, and mosses) and tracheophytes (vascular plants). Here we attempt to clarify this problem by analyzing a large transcriptomic dataset with models that al...
