in biotechnology has been concentrated to review alternative routes for the production of natural compounds. plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. however, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

Iranian bactrian camel (Camelus bactrianus) is an endangered livestock breed with distribution in northwest of Iran. Microsatellites are a powerful marker for animal genetic and cell line identification and population genetic study. In this study, after producing more than 40 Camelus bactrianus fibroblast cell lines, microsatellites loci from the genome of Iranian Camelus bactrianus cell lines ...

The ncc and nre nickel resistance determinants from Ralstonia eutropha-like strain 31A were used to construct mini-Tn5 transposons. Broad host expression of nickel resistance was observed for the nre minitransposons in members of the alpha, beta, and gamma subclasses of the Proteobacteria, while the ncc minitransposons expressed nickel resistance only in R. eutropha-like strains.

Filamentous fungi are rich resources of secondary metabolites (SMs) with a variety of interesting biological activities. Recent advances in genome sequencing and techniques in genetic manipulation have enabled researchers to study the biosynthetic genes of these SMs. Aspergillus terreus is the well-known producer of lovastatin, a cholesterol-lowering drug. This fungus also produces other SMs, i...

Mycemycins A-E are new members of the dibenzoxazepinone (DBP) family, derived from the gntR gene-disrupted deep sea strain Streptomyces olivaceus FXJ8.012Δ1741 and the soil strain Streptomyces sp. FXJ1.235. In this paper, we report the identification of the gene clusters and pathways' inference for mycemycin biosynthesis in the two strains. Bioinformatics analyses of the genome sequences of S. ...
