Morphology of Mosses (Phylum Bryophyta) - eFloras.org
WEBIn Sphagnum, leaf shape and cell pattern differ between the main stem and branches. In Tetrodontium protonema produce leaflike flaps and in Schistostega dimorphic shoots arise from the light-reflecting protonema.

WEBSome species of Sphagnum have retort cells (elongate cells with a pore terminating the upper end) associated with the surface of the stem. The leaves are very interesting organs because they can show a great degree of specialization between different species of moss.
How does moss photosynthesis relate to leaf and canopy …
WEBOct 23, 2009 · In Pyrrhobryum pungens, the leaf is primarily made up of a large costa lacking lamina, with chlorophyllous cells making up the outer layer of the costa. We first hypothesized that mosses would show traits associated with …
PpSCARECROW1 (PpSCR1) regulates leaf blade and mid-vein
WEBFeb 7, 2024 · RNA-Seq analyses revealed that genes responsible for cell division and differentiation are expressed differentially in the mutant. PpSCR1 overexpression lines exhibited significantly wider leaf lamina, further reconfirming the role in leaf development.

WEBSep 10, 2018 · Mosses (division Bryophyta) are characterized by the dominance of haploid, poikilohydric gametophytes, and relatively persistent sporophytes that are dependent on the gametophyte generation.
Development of the sphagnoid areolation pattern in leaves of …
WEBApr 11, 2018 · Having the general morphology of the Bryopsida, some have leaves with an areolation pattern characteristic of modern Sphagna. This study describes the structure and variation of these patterns in protosphagnalean mosses and provides a comparison with those of modern Sphagna.

WEBDec 1, 2003 · Most species of Sphagnum have extensive cell wall resorption near the leaf apices, and Eddy (1977) considered the cuspidate apices of S. sericeum leaves, lacking wall resorption, as plesiomorphic. The apiculae of stem leaves consist of uniformly thick-walled cells in S. sericeum ( Fig. 3B ).
