Journal of Phycology, 2009
As part of a long‐term study on the biology and ecology of the intertidal kelp Lessonia nigrescens Bory, we report on the occurrence of gall development on this alga, identified the possible causal agent, and assessed the extent of the phenomenon in two wild stands of the host.

Dictyota dichotoma (Phaeophyceae): Identification of the Sperm Attractant
Science, 1981Freshly released eggs of the marine brown alga Dictyota dichotoma secrete a substance that attracts spermatozoids. This compound has been identified as n -butyl-cyclohepta-2,5-diene. It is closely related to attractants in several other brown algae and confirms that a relation exists between ...

Plant regeneration from protoplasts of Sphacelaria (Phaeophyceae)
Planta, 1988Protoplast were isolated from a filamentous brown alga, Sphacelaria sp. (Sphacelariales, Phaeophyta), using alginate-lyases extracted from marine molluscs, and commercial pectinase and cellulase. Yields were about 4000 protoplasts per gram of fresh tissue.

Generic Circumscription in the Family Ectocarpaceae (Phaeophyceae)
Journal of the Marine Biological Association of the United Kingdom, 1978The family Ectocarpaceae currently contains the simplest, and probably also the most primitive, members of the Phaeophyceae. The thallus form of every species is a heterotrichous filament with little or no structural modification. Some species may possess quite extensive cortication of axial filaments by adventitious rhizoids but advanced ...
