HOMOTHALLIC AUXOSPORULATION IN PSEUDO‐NITZSCHIA BRASILIANA (BACILLARIOPHYTA)¹ [PDF]

Journal of Phycology, 2009
Most pennate diatoms are allogamous, and various types of mating systems have been described. In Pseudo‐nitzschia, reproductive stages have been identified in some species, and it is generally accepted that the genus is mainly heterothallic. Here we report homothallic auxosporulation of Pseudo‐nitzschia brasiliana Lundholm, Hasle et G. A. Fryxell.

Gene expression studies for the analysis of domoic acid production in the marine diatom Pseudo-nitzschia multiseries [PDF]

, 2013
Background: Pseudo-nitzschia multiseries Hasle (Hasle) (Ps-n) is distinctive among the ecologically important marine diatoms because it produces the neurotoxin domoic acid.

Biolistic Transformation of Pseudo-nitzschia multistriata and Pseudo-nitzschia arenysensis v1

, 2017
This protocol allows transformation of two species of Pseudo-nitzschia through biolistic method. With this method it is possible to insert one (transformation) or two (co-transformation) plasmids in the cells.

Modelling Pseudo-nitzschia events off southwest Ireland

Journal of Sea Research, 2015
Abstract Toxic and non-toxic Pseudo-nitzschia blooms are common in coastal waters worldwide including Ireland. Off southwest Ireland, the timing of blooms on a weekly scale is highly variable, while the seasonal pattern is more regular with a bimodal distribution. Upwelling conditions are closely linked to Pseudo-nitzschia blooms.

Identification and characterisation of the dominant Pseudo-nitzschia species (Bacillariophyceae) along the NE Spanish coast (Catalonia, NW Mediterranean)

Scientia Marina, 2008
Potentially toxic species of the genus Pseudo-nitzschia were studied along the Spanish NW Mediterranean coast from January 2005 to May 2006. Observation in electron microscopy revealed the presence of Pseudo-nitzschia brasiliana, P.

Monitoring bacterial composition and assemblage in the Gulf of Corcovado, southern Chile: Bacteria associated with harmful algae

Current Research in Microbial Sciences, 2023
Harmful Algal Blooms (HABs) have caused damage to the marine environment in Isla San Pedro in the Gulf of Corcovado, Chile. While rising water temperature and artificial eutrophication are the most discussed topics as a cause, marine bacteria is a recent

Toxic Pseudo-nitzschia multistriata (Bacillariophyceae) from the Gulf of Naples: morphology, toxin analysis and phylogenetic relationships with other Pseudo-nitzschia species [PDF]

European Journal of Phycology, 2002
The genus Pseudo-nitzschia includes several species capable of producing domoic acid, the causative agent of Amnesic Shellfish Poisoning. Some of these species have been recorded frequently in the Gulf of Naples. For one of the species, P. multistriata, which has been recurrently found in our sampling area since 1995, this is the first report for ...

Florecimiento de la diatomea potencialmente tóxica Pseudo-nitzschia cf. multistriata en aguas cubanas.

Revista de Investigaciones Marinas, 2023
Algunas especies de diatomeas del género Pseudo-nitzschia producen toxinas que causan envenenamiento amnésico por mariscos. En abril de 2009, se observó un florecimiento de diatomeas en un área semicerrada de la bahía de Cienfuegos, Cuba, en el que se ...
