14C 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 NaH14CO3 in seawater under controlled laboratory conditions. Over a 90‐min period roots and rhizomes absorbed very little 14C compared to leaves.

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 ...

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.

Marine Environmental Research, 2012
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

Mid‐Cretaceous Hothouse Climate and the Expansion of Early Angiosperms
Acta Geologica Sinica - English Edition, 2018The remarkable transition of early angiosperms from a small to a dominant group characterized the terrestrial ecosystem of the Cretaceous. This transition was instigated and promoted by environmental changes.

Disturbance‐related heterogeneity in the seed banks of a marine angiosperm
Journal of Ecology, 2000Summary 1 Patterns in the distribution of seeds of the marine angiosperm Halodule uninervis were described over spatial scales ranging from a few centimetres to meadows separated by more than 120 km along the north‐eastern coast of Queensland, Australia. Separate surveys examined how seed bank densities were related to: (i) the distribution of male and

Fitness-consequences of geitonogamous selfing in a clonal marine angiosperm (Zostera marina)
Journal of Evolutionary Biology, 2001Abstract Plant mating systems have received considerable attention because the proportion of selfed vs. outcrossed progeny is an important evolutionary factor. In clonally reproducing plants, geitonogamous selfing between distant ramets belonging to the same genet is expected to be widespread, yet empirical data are sparse.

Pollen germination and pollen tube growth in the marine angiosperm, Zostera marina L.
Aquatic Botany, 1993Abstract The marine angiosperms have adapted to a hydrophilous pollination mode, in which pollen is released and captured underwater. There has been some misunderstanding as to the fate of pollen following capture on stigmas. To address this question, naturally shed pollen grains were transferred to stigmas of carpellate flowers of Zostera marina L.
