Microbispora rosea subsp. aerata; Microbispora rosea subsp. rosea; Vochysia; endophytes; genes; medicinal plants; multilocus sequence typing; nucleotide sequences; phylogeny; probability; ribosomal RNA; species identification; topology
Abstract:
... The genus Microbispora has been considered difficult to define taxonomically. While 16S rRNA gene analysis is required to determine phylogenetic relationships among species in this genus, most 16S rRNA gene-based phylogenetic tree topologies are not reliable. The genus Microbispora currently contains eight species along with six reclassified species (Microbispora chromogenes, Microbispora diastati ...

Abstract:
... Sediment underlying the oxygen minimum zone of the eastern Arabian Sea is rich in organic matter. Bacteria in this sediment-water interface are of great ecological importance as they are responsible for decomposing, mineralizing and subsequent recycling of organic matter. This study has for the first time addressed the phylogenetic and functional description of culturable bacteria of this region. ...

In healthy individuals, this organism resides as a part of the normal microbiota in equilibrium with the host. However, under certain conditions, particularly in immunocompromised patients, this opportunistic pathogen adheres to host cells causing serious systemic in ...

Abstract:
... Operons are an important feature of prokaryotic genomes. Evolution of operons is hypothesized to be adaptive and has contributed significantly towards coordinated optimization of functions. Two conflicting theories, based on (i) in situ formation to achieve co-regulation and (ii) horizontal gene transfer of functionally linked gene clusters, are generally considered to explain why and how operons ...
