DNA sequencing of 1.3 kb of rDNA containing both internal transcribed spacers (ITS1, ITS2) and adjoining rRNA coding regions in each of 11 Echinococcus multilocularis isolates from Germany, Japan, and Alaska resulted in identical nucleotide sequences except for a single polymorphic locus 54 bp upstream of the 3' end of the 18S coding region, separating Eurasian isolates from an Alaskan isolate....

Intraand interspecific variation of the nu­ clear ribosomal internal transcribed spacers (ITS) of 77 Smittium isolates and related genera was studied using RFLP. Due to the sequence and length varia­ tion encountered, the ITS is unsuitable for compar­ ison at the species level within Smittium, as presently delimited. Intraand interspecific variation of 18S rDNA was also analyzed. Cladistic anal...

We developed a DNA microarray for identification of Bacillus anthracis and other phylogenetic groupings within the "Bacillus cereus group". Nucleotide sequences of 16S-23S ribosomal DNA internal transcribed spacers containing genes for tRNA(Ile) from 52 B. anthracis strains were found to be identical to sequences from seven strains published previously and different from all other bacteria. Whe...

Scutellaria wuana, a new species discovered from a xeric valley in Muli County of Sichuan Province in southwest China, is described and illustrated. Morphologically, the new species shares similarities with S. mairei, but can be readily distinguished by a suite of morphological characters including a white-pubescent erect stem, conspicuous leaf petioles, and a yellow corolla with a trapeziform ...

The genus Phyllanthus (Phyllanthaceae) is distributed in tropical and subtropical regions, and its members are widely used as medicinal plants in many countries. We analyzed the nucleotide sequences of the internal transcribed spacers of ribosomal DNA of 56 plant samples covering 23 Phyllanthus species collected from various habitats in Thailand. Based on the sequence alignment, we constructed ...

A method is described to prepare total DNA from single cells of dinoflagellates, which can be used for PCR amplification. As model organisms, we used a stock strain of Alexandrium catenella and cells of Dinophysis acuminata harvested from the Atlantic Ocean. Fresh grown cells or cells maintained in different preservatives were tested as sources for DNA preparation. The method used to prepare DN...

Saprolegnia bulbosa sp. nov. was isolated from floating and decaying twigs and leaves in El Gato stream, Partido de La Plata, Buenos Aires Province, Argentina. The distinctive characteristics of S. bulbosa are the product of smooth oogonia and predominantly contorted monoclinous, androgynous and diclinous antheridia. The oogonial stalks are usually bent, curved or once coiled; oospores are subc...
