Morphological diversity of coiled planktonic types of the genus Anabaena (cyanobacteria) in natural populations ? taxonomic consequences

Morphology of 61 planktonic populations of the genus Anabaena with coiled trichomes was studied under natural conditions. The samples were collected from Czech water bodies, representing all morphospecies that have previously been reported f...

Polyphasic characterization of three strains of Anabaena reniformis and Aphanizomenon aphanizomenoides (cyanobacteria) and their re-classification to Sphaerospermum gen. nov. (incl. Anabaena

Occurrences of rare cyanobacteria Anabaena reniformis and Aphanizomenon aphanizomenoides were found in the Czech Republic. Clonal strains were isolated from distant localities and different sampling years. They were characterized by combined...

Phylogenetic and morphological evaluation of the genera Anabaena, Aphanizomenon, Trichormus and Nostoc (Nostocales, Cyanobacteria)

This study was investigated the taxonomy of the genera Anabaena, Aphanizomenon, rpoB and rbcLX sequences. Data showed that benthic and planktic Anabaena strains were intermixed, confirmed that Anabaena and Aphanizomenon str...

A detailed morphological, phylogenetic and ecophysiological analysis of four benthic Anabaena (Nostocales, Cyanobacteria) strains confirms deep heterogeneity within the genus

Four benthic Anabaena strains isolated from different localities in the Czech is the first of its kind to be applied to benthic Anabaena strains. Our results indicate that the benthic Anabaena genus is much more complex tha...

Construction of Antisense RNA-mediated Gene Knock-down Strains in the Cyanobacterium Anabaena sp. PCC 7120

Anabaena sp. PCC 7120 (hereafter Anabaena) is a model cyanobacterium to study nitrogen fixation, cellular differentiation and several other key biological functions that are analogous in plants. As with any other organism, many gene...

Polyphasic characterization of eight planktonic Anabaena strains (Cyanobacteria) with reference to the variability of 61 Anabaena populations observed in the field

The plasticity of morphological features used for morphospecies identification was studied under varied experimental conditions in eight planktonic Anabaena strains. Significant effects of the growth conditions, mostly P concentration, on ve...

POLYPHASIC CHARACTERIZATION OF THREE STRAINS OF ANABAENA RENIFORMIS AND APHANIZOMENON APHANIZOMENOIDES (CYANOBACTERIA) AND THEIR RECLASSIFICATION TO SPHAEROSPERMUM GEN. NOV (INCL. ANABAENA

Occurrences of rare cyanobacteria Anabaena reniformis Lemmerm. and Aphanizomenon aphanizomenoides (Forti) Horecka et Komarek were recently detected at several localities in the Czech Republic. Two monoclonal strains of An. reniformis and one...
