Bee venom, which serves as a weapon to defend the colony from predator attacks, induces an immediate local inflammatory response that causes acute redness and swelling at the site of the sting. This venom-induced inflammation is a rapid anti-predatory defense strategy of the bee against vertebrate predators. Although acute inflammation by venom from venomous arthropods, including bees, is a typical response, how venom acutely elicits inflammatory responses remains unknown. Here, we identify a novel mechanism underlying acute inflammation and provide a rationale for the presence of superoxide dismutase (SOD3) in bee venom. In mouse models, paradoxically, SOD3 in bee venom (bvSOD3) acts as a reactive oxygen species (ROS)-based harm-inducing system to promote acute inflammation. Exogenous bvSOD3 rapidly induced overproduction of H2O2 through endogenously produced superoxide by venom components, such as melittin and phospholipase A2 (PLA2), which then upregulated the expression of proinflammatory genes and promoted the acute inflammatory response. Furthermore, a more severe noxious effect by bvSOD3 elevated a type 2 immune response, and bvSOD3 immunization protected against bvSOD3-mediated toxicity. Our findings that bvSOD3 promotes an acute inflammatory response and induces a protective immune response against inflammation may offer a new approach in venom therapy/immunotherapy.

In the present study, we make a first report on the complete mitochondrial DNA genome of Leptaulax koreanus, a Korean endemic species, in Passalidae. The mitogenome is 18,730 base pairs with 13 protein coding genes (PCGs), 22 tRNAs, two rRNAs and a 4240 bp long AT-rich region. The overall base composition is 78.4% AT and 21.6% GC. The maximum likelihood analysis inferred that L. koreanus is a sister to other Scarabaeoidea species. The phylogeny suggested that L. koreanus is the basal group of Scarabaeoidea.

Royal jelly (RJ) is a well-known functional and medicinal food for human health promotion. Major royal jelly proteins (MRJPs), which are the major protein components in RJ, exhibit antimicrobial activities. However, the identities of the MRJPs of RJ responsible for its antioxidant effects have remained unclear. Here, we report that honeybee (Apis cerana) MRJP 2 (AcMRJP2) acts as an antimicrobial and antioxidant agent in RJ. Using recombinant AcMRJP2, which was produced in baculovirus-infected insect cells, we established the antimicrobial and antioxidant roles of MRJP 2. AcMRJP2 bound to the surfaces of bacteria, fungi, and yeast, which then induced structural damage in the microbial cell walls and led to a broad spectrum of antimicrobial activities. AcMRJP2 protected mammalian and insect cells via the direct shielding of the cell against oxidative stress, which led to reduced levels of caspase-3 activity and oxidative stress-induced cell apoptosis, followed by increased cell viability. Moreover, AcMRJP2 exhibited DNA protection activity against reactive oxygen species (ROS). Our data indicate that AcMRJP2 could play a crucial role as an antimicrobial agent and antioxidant in RJ, suggesting that MRJP 2 is a component responsible for the antimicrobial and antioxidant activities of RJ.

Thrips from the genus Frankliniella (Thysanoptera, Thripidae) are a serious insect pest of various crops, including vegetables, fruits and ornamental plants. Thrips cause significant economic damage plants directly by feeding, and indirectly by acting as vectors for the tospoviruses such as Tomato spotted wilt virus (TSWV) and Chrysanthemum stem necrosis virus (CSNV) in chrysanthemum. To investigate the associations of thrips with tospoviruses and their ability to transmit, we have developed a protocol for identifying tospovirus and thrips species simultaneously in an individual thrips sample was successfully conducted. Total RNA was extracted from thrips according to manufacturer’s insturctions of RNeasy mini kit (Quiagen co.), and then TSWV was identified by reverse transcription-polymerase chain reaction (RT-PCR) using TSWV specific primers for the N genes. The residual genomic DNA in thrips RNA extract was used as a template to identify thrips species by PCR using universal primers for ITS2 region and subsequently digesting the PCR product by an restriction enzyme (RsaI) In addition, a classification into the species of thrips was confirmed using the nucleotide sequence of PCR products. The developed protocol was applied to investigate the occurrence of viruliferous thrips species in thrips populations collected from chrysanthemum fields. In this study, most of thrips were identified to Frankliniella spp. and thirps that acquire TSWV was 14 % of 65 thrips.

The red imported fire ants, Solenopsis invicta Buren are one of the serious pests in the world. Recently, S. invicta and S. germinata were found at Gamman pier, Pusan port in Korea by Animal and Plant Quarantine Agency. It is difficult to discriminate between S. invicta and S. germinata because of their morphology. Although DNA barcoding is an efficient method for species identification based on partial sequence of the mitochondrial cytochrome oxidase I gene(COI), amplification of non-target sequences or heteroplasmic COI sequences may result in the failure of Sanger sequencing. To overcome these limitations, application of next generation sequencing platforms is an alternative method. Here, we developed SNP markers using NGS technologies to distinguish two fire ants accurately and easily. For read mapping from high-throughput sequencing data, we used S. invicta reference genome version Si_gnG downloaded from NCBI database. Samtools were used for genotypes calling after mapping read to reference genome by BWA. After coding sequence SNPs that clearly distinguish S. invicta and S. geminata from one candidate gene were selected, the SNPs were validated additional Sanger sequencing using various accessions, including S. invicta and S. geminata. Our results demonstrated that detection of S. invicta from Solenopsis genus group could be accurately and quickly detected by these markers.

Insect-killing fungi have high potential in pest management. A deeper insight into the fungal genes at the whole genome level is necessary to understand the inter-species or intra-species genetic diversity of fungal genes, and to select excellent isolates. In this work, we conducted a whole genome sequencing of Beauveria bassiana (Bb) JEF-007 and characterized pathogenesis-related features and compared with other isolates including Bb ARSEF2860. A large number of Bb JEF-007 genes showed high identity with Bb ARSEF2860, but some genes showed moderate or low identity. The two Bb isolates showed a significant difference in vegetative growth, antibiotic-susceptibility, and virulence against Tenebrio molitor larvae. When highly identical genes between the two Bb isolates were subjected to real-time PCR, their transcription levels were different, particularly in heat shock protein 30 (hsp30) gene which is related to conidial thermotolerance. In several B. bassiana isolates, chitinases and trypsin-like protease genes involved in pathogenesis were highly conserved, but other genes showed noticeable sequence variation within the same species. Given the transcriptional and genetic diversity in B. bassiana, a selection of virulent isolates with industrial advantages is a pre-requisite, and this genetic approach could support the development of excellent biopesticides with intellectual property protection.

To control an external parasitic mite, a honey bee line possessing high hygienic behavior (HHB) against an external parasitic mite, Varroa destructor, has been bred in South Korea and an assessment method has been necessitated to diagnose HHB line from the low hygienic behavior (LHB) line. Thus, in this study, we developed single nucleotide polymorphism (SNP) markers from whole genome sequencing of each 20 worker bees from HHB and LHB lines of A. mellifera ligustica (Hymenoptera: Apidae). An average of 319,445,977 sequence reads was mapped to the known A. mellifera reference genome (an average of 87.46%). In 2,316,128 and 3,266,756 SNPs from each HHB and LHB line, an average of 93.6% and was located in the intergenic spacers and introns, whereas, the remaining 6.4% was located in the genic region, respectively. Among them 20 SNPs that were fixed at each line possessing within-individual homozygosity were selected and each four SNPs were used to diagnose the two honey bee lines either by typical PCR-restriction fragment length polymorphism method or allele-specific PCR. The remaining six SNPs had the size difference, enabling relatively easy differentiation between the two honey bee lines on typical agarose gel and another remaining six SNPs only has sequence difference including SNP sites. Thus, these SNP markers can be used to diagnose the honey bee line with HHB from LHB line against V. destructor.

The fruit fly, Drosophila melanogaster, is a good model organism in various areas of biological science. Since D. melanogaster has been thought to be adapted to the chemical stress environment caused by the overripen, decay and fermented fruits, identification of the genes involved in chemical tolerance and investigation of their expression patterns are essential for better understanding of the physiological evolution in D. melanogaster. For investigation of the gene expression level, quantitative real-time PCR (qRT-PCR) can be applied to quantify gene expression level and selection of reliable reference gene(s) for normalization is an accurate step. In the present study, therefore, we validated the expression stabilities of ten candidate reference genes using three softwares (geNorm, NormFinder and BestKeeper) in D. melanogaster exposed to different concentrations of acetic acid, ethanol and 2-phenylethanol. Although three programs resulted in slightly different gene stability ranks, but overall tbp encoding TATA box binding protein was most stable gene in acetic acid and ethanol exposed fly, while nd encoding NADH dehydrogenase was the most suitable reference gene in the case of 2-phenylethanol treatment. In the comparison of three chemical treatment condition, nd was also suggested to be most optimal reference gene. In addition, optimal number of reference gene for accurate normalization was calculated by geNorm pairwise analysis, and selection of multiple reference genes was suggested to be better for target gene normalization method than use of a single reference gene.

Virus-like particles (VLPs) are similar to pathogenic viruses, but because they have no nucleic acid, they have excellent safety and immunogenicity and are used as a good vaccine material. However, in the selection of various structural proteins of pathogenic viruses to form VLPs, all expression systems consume a lot of time in common. Among them, the baculovirus expression system causes additional time consumption to construct the recombinant baculovirus. Therefore, there is a need for a system that can rapidly determine the structural proteins required for effective VLP production. This study aims at solving this problem by constructing a BmNPV inducible expression platform through the construction of vectors induced by BmNPV. The platform was evaluated for overexpression using EGFP. We also confirmed the formation of virus-like particles through overexpression of canine parvovirus structural proteins.

Honey bee, Apis mellifera L., have been widely used as a model organism for biological science because of its highly developed sociality, specialized labor division and passive population management. In order to examine the expression patterns of genes putatively involved in social development in honey bee, quantitative real-time PCR (qRT-PCR) that has been widely used to investigate the expression level of target gene can be used in honey bee study. However, the selection and validation of optimal reference genes is a crucial step prior to running qRT-PCR. In the present study, therefore, the seasonal expression stability of five candidate reference genes in the abdomen of forager and nurse was investigated using three programs (geNorm, NormFinder and BestKeeper), and selected reference genes were validated by the normalization of expression level of vg encoding vitellogenin. Although three programs revealed slightly different gene stability values, overall the combination of two genes (rpS18 and gapdh encoding ribosomal protein S18 and glyceraldehyde-3-phosphate dehydrogenase, respectively) was resulted in the most suitable use for normalization of the target gene in forager. However, a single gene, either rpL32 or rpS18 in the nurse or either rpL32, rpS18, or gapdh in the comparison between foragers and nurses, were suggested to be applied for normalization of seasonal and labor-specific gene expression by qRT-PCR.
