The Rhodococcus strain WMMA185 was isolated from the marine sponge Chondrilla nucula as part of ongoing drug discovery efforts. Analysis of the 4.44-Mb genome provides information regarding interspecies interactions as pertains to regulation of secondary metabolism and natural product biosynthetic potentials.

A draft genome sequence of Cystobacter violaceus strain Cb vi76, which produces the eukaryotic protein synthesis inhibitor gephyronic acid, has been obtained. The genome contains numerous predicted secondary metabolite clusters, including the gephyronic acid biosynthetic pathway. This genome will contribute to the investigation of secondary metabolism in other Cystobacter strains.

Bacteria, which prey on other microorganisms, are commonly found in the environment. While some of these organisms act as solitary hunters, others band together in large consortia before they attack their prey. Anecdotal reports suggest that bacteria practicing such a wolfpack strategy utilize antibiotics as predatory weapons. Consistent with this hypothesis, genome sequencing revealed that the...

Streptomyces kanasensis ZX01 produces some antibiotics and a glycoprotein with antiviral activity. To further evaluate its biosynthetic potential, here we sequenced the 7,026,279 bp draft genome of S. kanasensis ZX01 and analyzed all identifiable secondary gene clusters for controlling natural products. More than 60 putative clusters were found in S. kanasensis ZX01, the majority of these biosy...

Fluorescence microscopy offers an important tool for the study of complex biological phenomena such as symbiosis. Here we identify a strategy that adapts the unique differences between the secondary metabolism in host and guest symbiotic species to selectively image endosymbiotic organisms. The method is demonstrated by application to the complex symbiotic relationships in toxic marine dinoflag...

Over the last two decades, the consumption of medicinal plants has increased in Mongolia. Once banned by the post-revolutionary government, it is now valued by the practitioners of orthodox medicine, government as well as by the society. Yet the scientific community has to give this major and crucial component of traditional Mongolian medicine the attention it deserves, scientific knowledge abo...

ATTENTION has been drawn to the possible adverse effects of anticonvulsant drugs on bone metabolism by a number of reports in recent years (Dent et al, 1970; Richens and Rowe, 1970; Hunter et al, 1971; Lifshitz and Maclaren, 1973; Stamp, 1974; British Medical Journal, 1976). The aim of the present study was to investigate this potentially serious side-effect of anticonvulsant therapy in the set...
