Characterization of HSP70 expression in drones of Apis cerana (Hymenoptera: Apidae)

Heat shock proteins (HSPs) constitute a superfamily of molecular chaperones that are rapidly biosynthesized in response to various biotic and abiotic factors. In this study, we first cloned the full-length HSP70 gene of the Eastern honeybee Apis cerana. Then, using real-time quantitative PCR, we explored HSP70 expression profiles in drones at different developmental stages, ages, and reproductive statuses (with and without semen). The fulllength HSP70 cDNA is 2421 bp, including a 1953-bp open reading frame (ORF) that encodes a polypeptide of 650 amino acids. The HSP70 gene consists of one intron and two exons. The phylogenetic analysis revealed that the HSP70 genes of A. cerana and Apis mellifera are the most closely related. We observed HSP70 expression at all selected developmental stages and detected the highest expression in pupae with an unpigmented body cuticle and brown eyes (Pb) and much lower expression in larvae hatched within 72 h. In adult drones of different ages, the highest expression level of HSP70 was observed in 16-day-old drones; significantly lower accumulation of HSP70 mRNA was detected in 4-day-old drones. There was no significant difference in HSP70 expression be tween drones with and without semen captured at the entrance, while the HSP70 gene expression level strikingly differed between drones captured at the entrance and the drones collected within the hive. Our study suggests that HSP70 might play a critical role in drone development and during reproductive mating events.

Chinese sacbrood virus (CSBV) is a disastrous virus that fatally threatens honeybees (Apis cerana) in China. Here, we identified the complete genome of CSBV using the rapid amplification of cDNA ends (RACE) method and compared the obtained sequences with those of other SBVs through multiple sequence alignment. The results showed that the full-length of CSBV genome from Zhejiang Province (CSBV-ZJ) is 8824 bp and contains a single, large open reading frame (ORF) that encodes 2842 amino acids flanked by 190 nucleotides (nts) of the 5′-untranslated region (UTR) and 108 nts of the 3′-UTR. The multiple genome comparison showed that SBVs have five conserved domains and that CSBV-ZJ belong to SBV type II. The phylogenetic analysis demonstrated that the CSBV-ZJ strain was similar to the CSBV from Fuzhou (CSBV-FZ) strain. Colonies collected from most of the sampling sites in the area surrounding Qiandao Lake were carriers of CSBV. The haplotypes of the VP1 gene formed a network with radiated and reticular structures. In conclusion, this characterization of the CSBV-ZJ genome will help us understand the SBV prevalence mechanism and aid the protection of honeybees.
