Summary Because of their large sizes and simple shapes, giant-celled algae have been used to study how the structural and mechanical properties of cell walls influence cell growth. Here we review known relationships between cell wall and cell growth

Cellulose microfibrils from Valonia ventricosa cell-wall fragments were immersed into molten N-methylmorpholine-N-oxide monohydrate (NMMO·H2O), stabilized with n-propyl gallate and kept at 80 °C. The resulting ultrastructural modifications, which w

The fine structures of the highly crystalline cellulose microfibrils from the cell walls of the marine algae Valonia ventricosa, and the extra cellular chitin spines of the euryhaline diatoms Thalassiosira fluviatilis, have been investigated by obser

Ornamental crabs of the genus Mithraculus (Decapoda: Brachyura: Majidae) are utilized in reef aquaria to control nuisance algae, particularly bubble algae. Although Mithraculus have modified, spooned-shaped chelae to feed on both fleshy and filamento

By injuring cells ofValonia ventricosa, one of two survival strategies — wound-healing and protoplast formation — is induced. The present study revealed that turgor pressure, as well as Ca2+ in bathing medium, is involved in the choice between th

The greater resolution afforded by the second-derivative mode has enabled differences previously observed in bands near 3240, 750, and 710 cm −1 in the FTIR spectra of Valonia and tunicin celluloses to be confirmed, and revealed new differences nea

The classical problem of chain-packing polarity in native cellulose fibres is approached by electron-diffraction analysis in fibrils of the alga Valonia ventricosa. Meridional reflections up to the 12th layer line were registered and compared with th

The structure of putative cellulose synthesizing complexes (TCs) has been studied in giant marine algae and is discussed in relation to the assembly of cellulose microfibrils. Including previous work, 14 species belonging to nine genera in the Siphon

Ventricaria ventricosa and its relatives have intrigued cell biologists and electrophysiologists for over a hundred years. Historically, electrophysiologists have regarded V. ventricosa as a large single plant cell with unusual characteristics includ
