Planta, 2004
The subcellular distribution of membrane-bound ATPases was compared among terrestrial plants, seagrasses and marine algae by cytochemical techniques. High ATPase activity was detected in the copiously invaginated plsma membrane that was characteristic of transfer cells but not in the tonoplast of epidermal cells in mature leaves of seagrasses ...

Mating System and Clonal Architecture: A Comparative Study in Two Marine Angiosperms
Evolutionary Ecology, 2005In the present study, we compared the clonal architecture between two seagrass species, the dioecious Cymodocea nodosa and the hermaphroditic, self-compatible Zostera noltii, in order to verify the hypothesis that clonal growth strategies and resulting genet architecture are associated with mating system in clonal plants.

An underlying mechanism of qE deficiency in marine angiosperm Zostera marina
Photosynthesis Research, 2021Non-photochemical quenching (NPQ) of photosystem II (PSII) fluorescence is one of the most important protective mechanisms enabling the survival of phototropic organisms under high-light conditions. A low-efficiency NPQ, characterized by weak NPQ induction capacity and a low level of protective NPQ, was observed in the marine angiosperm Zostera marina,

Plant Systematics and Evolution, 1990
Somatic chromosome numbers of 2n = 20 are reported for all eight species of AustralianPosidonia: P. angustifolia, P. australis, P. coriacea, P. denhartogii, P. kirkmanii, P. ostenfeldii, P. robertsonae, andP. sinuosa. All species apparently have five larger and five smaller pairs of chromosomes.

Phylogenetic Studies in Alismatidae, II: Evolution of Marine Angiosperms (Seagrasses) and Hydrophily
Systematic Botany, 1997Aquatic species represent fewer than two percent of all flowering plants, and only 18 aquatic genera have acquired true hydrophily (water-pollination) which is associated with an unusually high incidence of unisexual flowers. From the subset of submersed, hydrophilous angiosperms, only 13 genera have colonized marine habitats.

POLLEN WALL AND STIGMA SURFACE IN THE MARINE ANGIOSPERMS THALASSIA AND THALASSODENDRON.
Micron (1969), 1976Abstract The pollen wall and stigma surface of two tropical sea-grasses, Thalassia hemprichii and Thalassodendron ciliatum , have been investigated by electron microscopy and optical cytochemistry. In the spherical inaperturate pollen of Thalassia the exine consists of free bacula with a rudimentary foot layer and endexine. Non-specific esterase

Population biomass and metabolic rates of marine angiosperms on the northwestern Cuban shelf
Aquatic Botany, 1975Abstract Data on population biomass of turtle grass ( Thalassia testudinum ), manatee grass ( Syringodium filiforme ), and two species of the genus Halophila (H. decipiens and H. engelmanni ) from the northwestern Cuban shelf, as well as on metabolic rates of these and Halodule beaudettei , are given in this paper.

Polymorphic microsatellite loci for the marine angiosperm Cymodocea nodosa
Molecular Ecology Notes, 2004AbstractThe seagrass Cymodocea nodosa (UCRIA) Ascherson represents a good model to assess the relative contribution of clonal and sexual reproduction to genetic structure in marine plant populations. Seven microsatellite loci with repeat units consisting of one trinucleotide, four simple dinucleotides and two complex dinucleotides are described here ...
