Abstract Pseudo-nitzschia americana and the two closely related species P. brasiliana Lundholm, Hasle & G.A. Fryxell sp. nov. and P. linea Lundholm, Hasle & G.A. Fryxell sp. nov. are described, based on morphology. The phylogenetic positions of P. americana and P. brasiliana are inferred from partial nuclear-encoded large-subunit ribosomal DNA and their toxin production is assessed. The new species P. brasiliana and P. linea form stepped colonies, whereas P. americana is single celled. Pseudo…

MORPHOLOGY AND MOLECULAR CHARACTERIZATION OF PSEUDO‐NITZSCHIA (BACILLARIOPHYCEAE) FROM MALAYSIAN BORNEO, INCLUDING THE NEW SPECIES PSEUDO‐NITZSCHIA CIRCUMPORA SP. NOV

One morphotype from Sarawak, while somewhat similar to P. caciantha, showed significant morphological distinction from this and any other of the currently described species, and is here described as a new species, Pseudo‐nitzschia circumpora sp.

Phylogeny of the Bacillariaceae with emphasis on the genus Pseudo-nitzschia (Bacillariophyceae) based on partial LSU rDNA

A phylogenetic analysis of 42 species based on the first 872 base pairs of nuclear-encoded large subunit (LSU) rDNA suggested that Nitzschia is not monophyletic, as expected from the great morphological diversity within the genus.

Description of Pseudo-nitzschia cuspidata var. manzanillensis var. nov. (Bacillariophyceae): morphology and molecular characterization of a variety from the central Mexican pacific

A new pseudo-cryptic taxon is described within the Pseudo-nitzschia/pseudodelicatissima/cuspidata complex, as a variety of P. cuspidata.

The genus Pseudo-nitzschia (Bacillariophyceae) in Manzanillo and Santiago Bays, Colima, Mexico

Abstract In this study, morphological characters were used to describe the diversity and seasonal variability of the genus Pseudo-nitzschia in a coastal region of the Mexican tropical Pacific Ocean.

A polyphasic approach to the study of the genus Nitzschia (Bacillariophyta): three new planktonic species from the Adriatic Sea

Morphological analyses included LM, SEM, and TEM observations, which, along with specific morphometric features, allowed us to distinguish three new Nitzschia species, contributing to the overall diversity of genus NitzSchia, especially in identifying some deep branches within the Bacillariaceae, and highlight under‐scoring of this genus in marine plankton.

The genus Pseudo-nitzschia (Bacillariophyceae) in Malaysia, including new records and a key to species inferred from morphology-based phylogeny

For the first time high species richness of Pseudo-nitzschia is recorded in the confined coasts of Malaysia, with a special emphasis on the poroid structure of the striae to aid in species identification.

Inter- and intra-specific diversity of Pseudo-nitzschia (Bacillariophyceae) in the northeastern Mediterranean

Morphology and ITS2 phylogeny indicated that the level of diversity within the genus is higher than previously estimated (e.g. among P. delicatissima and P. galaxiae).

18S rDNA phylogeny of Pseudo-nitzschia (Bacillariophyceae) inferred from sequence-structure information

The 18S rDNA sequences of Pseudo-nitzschia and its close relatives, together with their individual secondary structure information to reconstruct phylogenies, yielded a more highly resolved phylogenetic framework for the Pseudo/Fragilariopsis clade than did the character-based analyses.

A new diatom species P. hallegraeffii sp. nov. belonging to the toxic genus Pseudo-nitzschia (Bacillariophyceae) from the East Australian Current

A new species belonging to the toxin producing diatom genus Pseudo-nitzschia, P. hallegraeffii sp. nov., is delineated and described from the East Australian Current (EAC). Clonal cultures were

IDENTIFICATION OF CULTURED PSEUDO‐NITZSCHIA (BACILLARIOPHYCEAE) USING SPECIES‐SPECIFIC LSU rRNA‐TARGETED FLUORESCENT PROBES 1

Whole‐cell hybridization is a rapid, simple, and cost‐effective technique for discriminating among cultured Pseudo‐nitzschia species.

Ribosomal DNA sequences discriminate among toxic and non-toxic Pseudonitzschia species.

The restriction test provides a rapid and convenient method for screening isolates' LsrDNA, facilitating further tests of the apparent positive correlation between Pseudonitzschia species' ribosomal gene signatures, morphology, and capacity to produce domoic acid.

Species of the planktonic diatom genus Pseudo-nitzschia of the Pacific coasts of Mexico

Net plankton samples obtained during several cruises and seasons from the Pacific coasts of Mexico were analyzed to study the species of the diatom genus Pseudo-nitzschia, finding the most common species was P. pungens, widely distributed along the Pacific coast of Mexico.

Identification of Pseudo-nitzschia australis (Bacillariophyceae) using rRNA-targeted probes in whole cell and sandwich hybridization formats

Large-subunit ribosomal RNA (LSU rRNA)-targeted oligonucleotides specific for Pseudo-nitzschia australis Frenguelli were used to discriminate that species from cultured isolates of P. pungens using whole cell (in situ) and sandwich hybridization.

On detection of pseudo‐nitzschia (bacillariophyceae) species using whole cell hybridization: sample fixation and stability 

Results indicate a wider window of opportunity for Pseudo‐nitzschia analysis using whole cell hybridization than previously reported and suggest large subunit ribosomal RNA (LSU rRNA)‐targeted fluorescent DNA probes could be adopted in the future to increase the rate of sample processing and decrease the cost of sample analysis.

PSEUDO‐NITZSCHIA AS A GENUS DISTINCT FROM NITZSCHIA (BACILLARIOPHYCEAE) 1

Characteristics including Colony formation by overlap of cell ends; weakly silicified, shallow, and flattened valves; an extremely eccentric raphe, not elevated above the general level of the valve; lack of con‐opea; and striated girdle bands characterize Pseudo‐nitzschia as a natural group and a genus separate from NitzSchia.

The morphology of the two forms is very similar, with overlapping measure­ ments of lengths, width, and number of costae in 10 pm, however, number of rows of poroid areolae or striae between costae are consistently different in culture when the two form are grown under similar conditions.
