J. Microbiol. Biotechnol.2016 ; 26(11):
|Abstract||Antimicrobial peptides/proteins (AMPs) are present in all types of organisms, from microbes
and plants to vertebrates and invertebrates such as insects. The grasshopper Oxya chinensis
sinuosa is an insect species that is widely consumed around the world for its broad medicinal
value. However, the lack of available genetic information for this species is an obstacle to
understanding the full potential of its AMPs. Analysis of the O. chinensis sinuosa transcriptome
and expression profile is essential for extending the available genetic information resources. In
this study, we determined the whole-body transcriptome of O. chinensis sinuosa and analyzed
the potential AMPs induced by bacterial immunization. A high-throughput RNA-Seq
approach generated 94,348 contigs and 66,555 unigenes. Of these unigenes, 36,032 (54.14%)
matched known proteins in the NCBI database in a BLAST search. Functional analysis
demonstrated that 38,219 unigenes were clustered into 5,499 gene ontology terms. In addition,
26 cDNAs encoding novel AMPs were identified by an in silico approach using public
databases. Our transcriptome dataset and AMP profile greatly improve our understanding of
O. chinensis sinuosa genetics and provide a huge number of gene sequences for further study,
including genes of known importance and genes of unknown function.|
