Abstract
BACKGROUND Bees (Apis mellifera), as important pollinators of agricultural crops, are at risk when pesticides are used. Sulfoxaflor is a new insecticide which acts on the nicotinic acetylcholine receptor (nAChR) in a similar way to neonicotinoids. The goal of this study is to evaluate the toxicity of sulfoxaflor and its effect on the A. mellifera exposure. RESULTS Initially, developmental indicators such as larval survival, pupation, and eclosion were inhibited by 5.0 mg/L (field concentration) sulfoxaflor. In the pupal stage, fat content was significantly increased, while the glycogen content decreased. In addition, A. mellifera heads were treated with 2.0 mg/L (sublethal concentration) of sulfoxaflor and analyzed by RNA sequencing. The transcriptome results indicated that 2.0 mg/L amounts of sulfoxaflor have adverse effects on the immune, digestive, and nervous systems. Sulfoxaflor down-regulated the expression of many genes involved in immunity, detoxification, the myosin cytoskeleton, sensory neurons, and odor-binding proteins. CONCLUSION Field concentration and sublethal concentration were used for the combined analysis of honeybees. The effect of sublethal concentration of sulfoxaflor on honeybees was studied for the first time from the perspective of transcriptome sequencing of honeybee head. A preliminary study was carried out on the stress of sulfoxaflor at sublethal concentration on honeybee workers, which has certain research significance and can provide theoretical basis for the use of sulfoxaflor in the field environment. © 2024 Society of Chemical Industry.

Chao Y, Wang C, Jia H, Zhai N, Wang H, Xu B, Li H, Guo X. Identification of an Apis cerana cerana MAP kinase phosphatase 3 gene (AccMKP3) in response to environmental stress. Cell Stress Chaperones 2019; 24:1137-1149. [PMID: 31664697 PMCID: PMC6882995 DOI: 10.1007/s12192-019-01036-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 08/23/2019] [Accepted: 09/23/2019] [Indexed: 12/26/2022] Open
Abstract
MAP kinase phosphatase 3 (MKP3), a member of the dual-specificity protein phosphatase (DUSP) superfamily, has been widely studied for its role in development, cancer, and environmental stress in many organisms. However, the functions of MKP3 in various insects have not been well studied, including honeybees. In this study, we isolated an MKP3 gene from Apis cerana cerana and explored the role of this gene in the resistance to oxidation. We found that AccMKP3 is highly conserved in different species and shares the closest evolutionary relationship with AmMKP3. We determined the expression patterns of AccMKP3 under various stresses. qRT-PCR results showed that AccMKP3 was highly expressed during the pupal stages and in adult muscles. We further found that AccMKP3 was induced in all the stress treatments. Moreover, we discovered that the enzymatic activities of peroxidase, superoxide dismutase, and catalase increased and that the expression levels of several antioxidant genes were affected after AccMKP3 was knocked down. Collectively, these results suggest that AccMKP3 may be associated with antioxidant processes involved in response to various environmental stresses.

Molecular mechanism by which Apis cerana cerana MKK6 ( AccMKK6)-mediated MAPK cascades regulate the oxidative stress response. Biosci Rep 2018; 38:BSR20181301. [PMID: 30442872 PMCID: PMC6294647 DOI: 10.1042/bsr20181301] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 11/08/2018] [Accepted: 11/11/2018] [Indexed: 01/30/2023] Open
Abstract
Mitogen-activated protein kinase kinases (MKKs) are important components of the MAPK signaling pathways, which play a key role in responding to stress and inflammatory stimuli. Here, a new MKK gene, AccMKK6, was identified and functionally analyzed in Apis cerana cerana. Real-time quantitative PCR (qPCR) and Western blot analysis demonstrated that the AccMKK6 expression level was up-regulated by several environmental stresses. Moreover, the knockdown of AccMKK6 by RNA interference technology altered the expression levels of some antioxidant genes. In addition, the knockdown of AccMKK6 resulted in increased malonyldialdehyde (MDA) concentration and decreased antioxidant-related enzymes activity in honeybees. To explore the MAPK signaling pathways involved in AccMKK6, we identified the transcription factor kayak in A. cerana cerana. We analyzed the interactions of AccMKK6, Accp38b, and Acckayak using the yeast two-hybrid system. AccMKK6 and Acckayak showed similar expression profiles after several stress treatments. In addition, the expression level of Acckayak was significantly increased when AccMKK6 was silenced. Therefore, we speculate that AccMKK6 may be involved in the MAPK cascades, which play a crucial role in counteracting oxidative stress caused by external stimuli.

Abstract
DnaJ, also known as Hsp40, plays important roles in maintaining the normal physiological state of an organism under stress conditions by mediating essential processes, such as protein synthesis, degradation, folding and metabolism. However, the exact functions of most DnaJ members are not fully understood in insects. Here, we identified three genes, AccDnaJA1, AccDnaJB12, and AccDnaJC8, in Apis cerana cerana and explored their connection with the environmental stress response. Quantitative real-time PCR results showed that the mRNA levels of AccDnaJA1, AccDnaJB12, and AccDnaJC8 were all induced under cold, UV, H2O2 and different pesticides treatment. The expression patterns of AccDnaJB12 and AccDnaJC8 were upregulated by CdCl2 and HgCl2 stress, while the transcriptional levels of AccDnaJA1 were downregulated by CdCl2 and HgCl2 stress. Western blot findings further indicated that AccDnaJB12 protein levels were increased by some stress conditions. Knockdown of each of these three genes downregulated the transcriptional patterns of several stress response-related genes at different levels. Functional analysis further demonstrated that the resistance of A. cerana cerana to lambda-cyhalothrin stress was reduced with knockdown of AccDnaJA1, AccDnaJB12, or AccDnaJC8, indicating that these three genes may be involved in the tolerance to this pesticide. Taken together, these findings indicate that AccDnaJA1, AccDnaJB12, and AccDnaJC8 may play pivotal roles in the stress response by facilitating honeybee survival under some adverse circumstances. To our knowledge, this is the first report that reveals the roles of DnaJ family proteins under different adverse circumstances in A. cerana cerana.

Abstract
As one of the predominant pollinator, honeybees provide important ecosystem service to crops and wild plants, and generate great economic benefit for humans. Unfortunately, there is clear evidence of recent catastrophic honeybee colony failure in some areas, resulting in markedly negative environmental and economic effects. It has been demonstrated that various environmental stresses, including both abiotic and biotic stresses, functioning singly or synergistically, are the potential drivers of colony collapse. Honeybees can use many defense mechanisms to decrease the damage from environmental stress to some extent. Here, we synthesize and summarize recent advances regarding the effects of environmental stress on honeybees and the wisdom of honeybees to respond to external environmental stress. Furthermore, we provide possible future research directions about the response of honeybees to various form of stressors.
