Abstract:
Stenotrophomonas maltophilia strain R551-3 is a multiple-antibiotic-resistant opportunistic human pathogen involved in nosocomial infections. It has a widely distributed GC-rich (>66%) genome. Analysis of differential expression of the genes of this genome reveals that majority of genes belonging to highly expressed category are mostly present on lagging strand without showing any strand specific codon usage bias. Relatively small number of lowly expressed genes is equally distributed on both leading and lagging strands with a difference in codon usage pattern between them. Among several multi drug resistance genes of S. maltophilia involving lowly expressed category some are predicted as horizontally transferred. It can be inferred that horizontally transferred genes may have been imported into this genome for their pathogenic mode of living. Our study may help to modify the expression level of the target genes of this human pathogen in order to control its infection.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
