Seasonal dynamics of the microbiota and nutritional composition in bee bread from Apis cerana and Apis mellifera colonies.

Bee bread is a product of honeybees, which collect and ferment pollen, that contains highly nutritious and easily digestible active substances. However, its nutritional composition varies significantly with fermentation strains and seasonal changes. To unveil the patterns of microbial community and nutritional component changes in bee bread across seasons, we employed high-throughput techniques to assess the diversity of bacteria and fungi in bee bread.

Glyphosate exposure affected longevity-related pathways and reduced survival in asian honey bees (Apis cerana).

Glyphosate (N-(phosphonomethyl)glycine, GLY) ranks among the most extensively used and effective herbicides globally. However, excessive GLY utilization poses a substantial threat to the survival of honey bees (Apis cerana). Here we monitored the survival status of A.

Gut microbiota-driven regulation of queen bee ovarian metabolism.

With the global prevalence of mites, more and more beekeepers resort to confining the queen bee in a queen cage to control mite infestation or to breed superior and robust queen bees. However, the impact of such practices on the queen bee remains largely unknown. Therefore, we subjected the queen bees to a 21-day egg-laying restriction treatment (from the egg stage to the emergence of adult worker bees) and analyzed the queen bees' ovarian metabolites and gut microbiota after 21 days, aiming to assess the queen bees' quality and assist beekeepers in better hive management.

Honeybee (Apis mellifera) resistance to deltamethrin exposure by Modulating the gut microbiota and improving immunity.

Honeybees (Apis mellifera) are important economic insects and play important roles in pollination and maintenance of ecological balance. However, the use of pesticides has posed a substantial threat to bees in recent years, with the more widely used deltamethrin being the most harmful. In this study, we found that deltamethrin exposure significantly reduced bee survival in a dose-dependent manner (p = 0.

The composition of bacteria in gut and beebread of stingless bees (Apidae: Meliponini) from tropics Yunnan, China.

Stingless bees are the main pollinators in tropical and subtropical regions. However, there are only a few studies on the structure and composition of bacteria in the gut and beebread of stingless bees, especially in China. To address this shortage of information, we characterized the microbiota of three common species of stingless bees (Lepidotrigona terminata, Lepidotrigona ventralis and Tetragonula pagdeni) and beebread samples of T.

The Succession of the Gut Microbiota in Insects: A Dynamic Alteration of the Gut Microbiota During the Whole Life Cycle of Honey Bees ().

The Asian honey bee is a valuable biological resource insect that plays an important role in the ecological environment and agricultural economy. The composition of the gut microbiota has a great influence on the health and development of the host. However, studies on the insect gut microbiota are rarely reported, especially studies on the dynamic succession of the insect gut microbiota.

Exposure to benzo[a]pyrene triggers distinct patterns of microRNA transcriptional profiles in aquatic firefly Aquatica wuhana (Coleoptera: Lampyridae).

Larval aquatic fireflies in fresh water are adversely affected by water pollutants such as benzo(a)pyrene (BaP). However, their response to BaP stress at the microRNA (miRNA)-regulatory level remains unknown. Here, transcriptomes containing 31,872 genes and six miRNA transcriptional profiles were obtained for Aquatica wuhana larvae, and comparative analysis was performed between larvae exposed to BaP (0.

Comparative analysis of the gut microbiota of Apis cerana in Yunnan using high-throughput sequencing.

Gut microbes play an important role in host disease and health. The Asian honey bee Apis cerana is an important pollinator of agricultural crops in China. However, there are still few studies on the structure and composition of the microbiota in the intestine of A.

Comparative transcriptomic analysis of fireflies (Coleoptera: Lampyridae) to explore the molecular adaptations to fresh water.

Aquatic insects are well adapted to freshwater environments, but the molecular basis of these adaptations remains largely unknown. Most firefly species (Coleoptera: Lampyridae) are terrestrial, but the larvae of several species are aquatic. Here, larval and adult transcriptomes from Aquatica leii (freshwater) and Lychnuris praetexta (terrestrial) were generated to test whether the genes associated with metabolic efficiency and morphology have undergone adaptive evolution to fresh water.

The impact of mercury on the genome-wide transcription profile of zebrafish intestine.

Mercury is a widely used heavy metal that causes pollution to aquatic environments and severely affects the health of fish. Little is known about how heavy metal pollutants affect fish, particularly for gene expression within important organs such as the intestine. Herein, whole transcriptome sequencing was performed on zebrafish (Danio rerio) intestine tissue after HgCl (HGC, 30 μg/L) exposure.

Colonization of the gut microbiota of honey bee (Apis mellifera) workers at different developmental stages.

The role of the gut microbiome in animal health has become increasingly evident. Although the structure of the gut microbiome of A. mellifera is well known, little is known about the dynamic change across different developmental stages.

MicroRNA profile of immune response in gills of zebrafish (Danio rerio) upon Staphylococcus aureus infection.

The gills of fish are large mucosal surfaces that are very important portals for pathogen entry. Investigations have shown that microRNAs (miRNAs) are key regulators of immune response to bacterial infections in the gills of fish; however, how miRNA expression changes in response to infection by Gram-positive bacteria remains largely unknown. To further investigate the immunological role of miRNAs in fish gills under pathogen stress induced by Gram-positive bacterial infection, this study investigated Staphylococcus aureus (SA)-induced changes in the miRNAs levels in gills of adult zebrafish (Danio rerio).

A Phylogenomic Framework and Divergence History of Cephalochordata Amphioxus.

Amphioxus, or cephalochordates, are often used as the living invertebrate proxy of vertebrate ancestors and are widely used as evolutionary biology models of chordates. However, their phylogeny, divergence history, and speciation characteristics remain poorly understood, and phylogenomic studies to explore these problems lacking entirely from the literature. Here, we determined a new transcriptome of .
