Project description:Honeybees are ecologically indispensable pollinators and an important resource for biologically active natural products. Among honeybee taxa, Apis dorsata (the giant Asian honeybee) is a wild, open-nesting species distributed across South and Southeast Asia that displays distinct behavioral and ecological traits compared with domesticated species such as Apis mellifera and Apis cerana. Despite its ecological prominence and frequent human–bee interactions, A. dorsata has received comparatively little molecular characterization, and its venom proteome remains poorly described. This work establishes a foundational molecular inventory for A. dorsata venom and underscores the species’ value as a source of novel bioactive compounds for future biochemical and pharmacological exploration.

Project description:To explore brain neuropeptidic functions in behavioral regulation, a label-free quantitative strategy was employed to compare neuropeptidomic variations between behavioral phenotypes (nurse bees, nectar foragers, and pollen foragers) and the two honeybee species (Apis mellifera ligustica and Apis cerana cerana).
Project description:Honeybee brain has distHoneybee brain has distinct anatomical and functional regions, knowledge on molecular underpinnings of sub-organ to achieve the distinct neural function and the difference between the eastern and western honeybees are still missing. Here, the proteomes of three sub-organs of eastern and western honeybee brains were compared. Mushroom bodies (MBs) and optical lobes (OLs) may by employed similar proteome architectures to drive their domain-specific neural activity in both bee species. In MBs, protein metabolism and Ca2+ transmembrane transport are the key role players in driving the learning and memory by modulating the synaptic structure and signal transduction to consolidate memory trace. In OLs, ribonucleoside metabolism and energy production play major roles to underpin visual system by maintaining G-protein cycle and membrane electrical charge potential. However, in antennal lobes (ALs), it has evolved distinct proteome settings to prime the olfactory learning and memory in two bee species. In ALs of Apis cerana cerana (Acc), actin cytoskeleton organization is key for plasticity of glomeruli and intracellular transport to sustain the olfactory signaling. Whereas, in ALs of Apis mellifera ligustica (Aml), hydrogen and hydrogen ion transport are vital to support olfactory process by supplying energy and maintaining molecule transport. Noticeably, in ALs of Acc, the exclusively enriched functional groups acting as second messenger and neurontransmitter of signal transduction, and the enhanced protein metabolism to regulate the plasticity of synaptic structure for formation of memory, suggest that Acc may have evolved a better sense of smell than that of Aml. Our first proteome data is helpful as starting point for further analysis of neural activity in brain sub-area of honeybee and other insects.inct anatomical and functional regions, knowledge on molecular underpinnings of sub-organ to achieve the distinct neural function and the difference between the eastern and western honeybees are still missing.

Project description:The proboscis of Apis cerana cerana is primarily recognized as a feeding organ; however, its potential role in close-range chemical perception during foraging remains insufficiently understood. While antennal olfaction has been extensively investigated, whether the proboscis contributes to volatile signal detection and how it responds transcriptionally under different foraging conditions are still unclear. This study aimed to integrate ultrastructural and transcriptomic analyses to elucidate the morphological basis and olfactory-related molecular responses of the proboscis under distinct foraging states.
