Morphology of Mosses (Phylum Bryophyta)
With over 12,000 species recognized worldwide (M. R. Crosby et al. 1999), the Bryophyta, or mosses, are the most speciose of the three phyla of bryophytes. The other two phyla are Marchantiophyta or liverworts and Anthocerotophyta or hornworts. The term “bryophytes” is a general, inclusive term for these three groups though they are only superficially related. Mosses are widely distributed from...
متن کاملEndogenous auxin and ethylene in pellia (bryophyta).
The occurrence of endogenous indole-3-acetic acid and ethylene in bryophyte tissue was tentatively demonstrated using gas chromatography, high performance liquid chromatography, and double-standard isotope dilution techniques. Rapidly elongating stalks (or setae) of Pellia epiphylla (L.) Corda sporophytes contain approximately 2.5 to 2.9 micrograms per gram fresh weight of putative free IAA. Et...
متن کاملChemical and structural characterization of copper adsorbed on mosses (Bryophyta).
The adsorption of copper on passive biomonitors (devitalized mosses Hypnum sp., Sphagnum denticulatum, Pseudoscleropodium purum and Brachythecium rutabulum) was studied under different experimental conditions such as a function of pH and Cu concentration in solution. Cu assimilation by living Physcomitrella patents was also investigated. Molecular structure of surface adsorbed and incorporated ...
متن کاملMacula densa cell signaling.
Macula densa cells are renal sensor elements that detect changes in distal tubular fluid composition and transmit signals to the glomerular vascular elements. This tubuloglomerular feedback mechanism plays an important role in regulating glomerular filtration rate and blood flow. Macula densa cells detect changes in luminal sodium chloride concentration through a complex series of ion transport...
