Aquatic ferns from Viçosa (MG, Brazil): Salviniales (Filicopsida; Tracheophyta)
Brazilian Journal of Botany, 2016This work presents the species of Salviniales occurring in the region of Vicosa, MG, Brazil. There, two species occur naturally (Azolla microphylla Kaulf. and Salvinia auriculata Aubl.), three spontaneously (Marsilea ancylopoda A. Braun, S. minima Baker, and S. molesta D.S. Mitch.), and one in cultivation (S. biloba Raddi). Both S.

Devonian Spores of Kryshtofovichia africani Nikitin (Tracheophyta): Morphology and Ultrastructure
Paleontological Journal, 2018The morphology and ultrastructure of spores of the Devonian plant Kryshtofovichia africani Nikitin are examined. The structure of ultrathin exine megaspores of K. africani is established. The exine consists of two layers: granular ectexine and lamellate endexine. Microspores have a lamellate ultrastructure with a trend toward loosening and formation of

Cyanogenic Compounds as Systematic Markers in Tracheophyta
1977A short chronological review of cyanogenesis (Fig. 1) in vascular plants is given (Table 1). Subsequently the chemistry (Tables 2–4; Fig. 2) and biochemistry (Figs. 3–9) of cyanogenic plant constituents are summarized. Five biogenetical groups (A-E) of cyanogenetic compounds are presently known from vascular plants. The occurrence and function (Fig. 10)

Plant-TypeN-Glycans Containing Fucose and Xylose in Bryophyta (Mosses) and Tracheophyta (Ferns)
Bioscience, Biotechnology, and Biochemistry, 2007The presence of typical plant-type N-glycans (eg, M3FX, Gn2M3FX, and Le(a)2M3FX) in mosses, ferns, and other organisms was examined to determine which plant initially acquired glycosyltransferases to produce plant-type N-glycans during organic evolution. No M3FX-type N-glycan was detected in lichens (Cladonia humilis) or in any one of the three preland

Syringodium filiforme Kützing 1860 is the second species of marine angiosperm in importance due its abundance of the Caribbean Sea and Cuba. The presence of a patch of this species with an unusual length on the leaves and vertical rhizome was detected at the north coast of Villa Clara, Cuba. The measurements made on a sample are presented, which showed
