title: Variations in major toxin composition for six clones of Ptychodiscus brevis.
abstract: Extracts from six clones of Ptychodiscus brevis (formerly known as Gymnodinium breve) were analyzed by high performance liquid chromatography for the presence of brevetoxins PbTx-1, PbTx-2, and PbTx-3. Analyses indicated a wide clonal variability of the three toxin fractions in logarithmic phase cultures when normalized on a per cell basis. It appears that a much wider variability exists in toxin content for different P. brevis clones than exists in replicate extraction of multiple cultures of the diploid clone originally isolated by Wilson.
