Inbreeding depression influences genet size distribution in a marine angiosperm
Molecular Ecology, 2003AbstractAlthough inbreeding depression is a major genetic phenomena influencing individual fitness, it is difficult to measure in wild populations. An alternative approach is to correlate heterozygosity, measured using highly polymorphic markers, with a fitnessâcorrelated trait. In clonal plants, genet size is predicted to be fitness correlated.

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.

Studies of storage reserves in seeds of the marine angiosperm Zostera capricorni
Aquatic Botany, 1992Abstract The structure of Zostera capricorni Aschers, seeds was determined to be similar to that of Zostera marina L. Staining with Lugol's iodine revealed large quantities of starch in all tissues of the embryo. Other stains revealed smaller amounts of lipids and proteins. Electron-dense globoid crystals were present in all tissues of the embryo.

The Unusual Epidermis of the Marine Angiosperm Halophila Thou
Flora, 1974Summary Examination of the ring-like annuli, situated within the surface walls of the epidermis of Halophila ovalis , revealed that both the annulus, and a site beneath it on the inside of the exterior epidermal wall reacted strongly to silver nitrate. It is suggested that the annulus and associated vacuole may be important localised sites affecting

Mechanistic implications for pollination in the marine angiosperm Zostera marina
Aquatic Botany, 1986Abstract Zostera marina L. must pollinate underwater. In an attempt to understand this undescribed process, hydrophily, current-flow patterns were examined both around carpellate flowers in the laboratory and a community in the field. A description of these patterns of flow is essential as a first approximation to understanding actual pollen ...

14 C UPTAKE BY THE MARINE ANGIOSPERM PHYLLOSPADIX SCOULERP
American Journal of Botany, 1979Rhizomes and attached leaves of Phyllospadix scouleri Hook, were collected in the intertidal zone along the central California coast and exposed to a solution of NaH 14 CO 3 in seawater under controlled laboratory

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

In flowering plants, floral homeotic MADS-box genes, which constitute a large multigene family, play important roles in the specification of floral organs as defined by the ABCDE model. In this study, a MADS-box gene, ZjMADS1, was isolated and characterized from the marine angiosperm Zostera japonica. The predicted length of the ZjMADS1 protein was 246
