Relationships between growth, morphology and wall stress in the stalk of Acetabularia acetabulum
Planta, 2001With carbon particles we analyzed patterns of growth in Acetabularia acetabulum (Lam.) P.C. Silva, a giant unicell famous for classic development studies. We focused on the stalk apex, which generates the stalk, whorls of hairs, and whorls of gametophores.

Vegetative adults of Acetabularia acetabulum (L.) Silva were studied as a model system for subcellular patterning in plants, and a description of several phenotypic and physiological characteristics that reveal patterns of subcellular differentiation in this unicellular macroalga was undertaken. Initially, calcification patterns were studied.

Physical aspects of delayed luminescence inAcetabularia acetabulum
Experientia, 1993Delayed photo-induced luminescence has been studied inAcetabularia acetabulum individuals. The number of photons re-emitted when the wavelength, the intensity, or the duration of the incident radiation were varied are reported for 10 individuals. Reproducibility of the measurements in the same and in different individuals was good.

Three features of chloroplast DNA (cpDNA) in plastids isolated from Acetabularia mediterranea (acetabulum) were analyzed after staining the organelles with the fluorochrome 4′6-diamidino-2-phenyl indole (DAPI): (1) number of chloroplasts exhibiting DNA fluorescence, (2) number of nucleoids per plastid, and (3) nucleoid morphology.

Analogous features of delayed luminescence from Acetabularia acetabulum and some solid state systems
Journal of Photochemistry and Photobiology B: Biology, 2000This paper compares some features of the delayed luminescence in the seconds range emitted from an unicellular alga Acetabularia acetabulum and from some solid state systems. Results lead us to think that such delayed luminescence is connected to the dimension of the ordered structures present in both biological and solid state systems.

Abstract This article shows that the photoinduced delay luminescence in the seconds time range emitted from a unicellular alga Acetabuluria acetabulum is influenced in selective way by the presence of atrazine in the matrix. The presence of atrazine is noticeable up to a concentration of about 0.5 μg l −1 .

Abstract The endolithic activity of the green alga Acetabularia acetabulum (Linnaeus) P.C. Silva, 1952 (Ulvophyceae, Dasycladales, Polyphysaceae) was documented on different lithotypes recovered in the Underwater Archaeological Park of Baiae (Naples). The results show that rhizoids of A.

Abstract To facilitate genetic selections of Acetabularia acetabulum (Linnaeus) P.C. Silva (Dasycladales, Chlorophyta), two culture techniques which reduce the labour in handling large cell populations and the life-cycle duration of this giant alga are described and quantified.

AbstractMarine algae are one of the most important sources of high‐value compounds such as polar lipids, omega‐3 fatty acids, photosynthetic pigments, or secondary metabolites with interesting features for different niche markets. Acetabularia acetabulum is a macroscopic green single‐celled alga, with a single nucleus hosted in the rhizoid.

Protoplasma, 2003
Effects on morphology and microfilament structure caused by phalloidin, phallacidin, and some semisynthetic phalloidin derivatives were studied in vegetative cells of the green alga Acetabularia acetabulum (L.) Silva. All phalloidin derivatives (except for phalloidin itself) caused growth stop of the alga after 1 day and (except for the fluorescein ...
