BACKGROUND Polyketides are natural products with a wide range of biological functions and pharmaceutical applications. Discovery and utilization of polyketides can be facilitated by understanding the evolutionary processes that gave rise to the biosynthetic machinery and the natural product potential of extant organisms. Gene duplication and subfunctionalization, as well as horizontal gene tran...

We report the genome of the facultative intracellular parasite Rhodococcus equi, the only animal pathogen within the biotechnologically important actinobacterial genus Rhodococcus. The 5.0-Mb R. equi 103S genome is significantly smaller than those of environmental rhodococci. This is due to genome expansion in nonpathogenic species, via a linear gain of paralogous genes and an accelerated genet...

Changes in a patient’s patterns of cocaine use are generally considered an important outcome measure of treatment efficacy. Other treatment outcome measures are important as well, but if a treatment does not stop or significantly decrease the intensity of a cocaine addict’s cocaine use, many would question the treatment’s efficacy. Examination of a patient’s urine for evidence of cocaine or coc...

The role of RbpA in the backdrop of M. smegmatis showed that it rescues mycobacterial RNA polymerase from rifampicin-mediated inhibition (Dey et al., 2010; Dey et al., 2011). Paget and co-workers (Paget et al., 2001; Newell et al., 2006) have revealed that RbpA homologs occur exclusively in actinobacteria. Newell et al. (2006) showed that MtbRbpA, when complemented in a ∆rbpA mutant of S. coeli...

Host-parasite associations are potentially shaped by evolutionary reciprocal selection dynamics, in which parasites evolve to overcome host defences and hosts are selected to counteract these through the evolution of new defences. This is expected to result in variation in parasite-defence interactions, and the evolution of resistant parasites causing increased virulence. Fungus-growing ants ma...

In Sumatra, Indonesia, increased oil palm production encourages land expansion for plantations. And soil Actinobacteria have a potential role in agriculture and plantations ecosystems. The use of fertilizer herbicide affects microbial diversity, including Actinobacteria. This research analyzed investigated the community composition diversity soils Jambi Sumatra. Amplicon-based analysis 16S rRNA...
