Bacteriocytes are specialized insect cells adapted to harbor symbionts. However, their low number in individual whiteflies makes obtaining enough for transcriptome sequencing challenging. Here, we present a protocol for the isolation of whitefly bacteriocytes. We describe steps for preparing the single bacteriocyte sample, cDNA amplification library construction, sequencing, and data analysis. Our protocol offers convenience and efficiency for conducting single-cell sequencing for bacteriocytes and has the potential to be applied to other insect cells. For complete details on the use and execution of this protocol, please refer to Li et al..

DNA repair systems are essential to maintain genome integrity and stability. Some obligate endosymbionts that experience long-term symbiosis with the insect hosts, however, have lost their key components for DNA repair. It is largely unexplored how the bacterial endosymbionts cope with the increased demand for mismatch repairs under heat stresses.

Bathymodioline mussels dominate deep-sea methane seep and hydrothermal vent habitats and obtain nutrients and energy primarily through chemosynthetic endosymbiotic bacteria in the bacteriocytes of their gill. However, the molecular mechanisms that orchestrate mussel host-symbiont interactions remain unclear. Here, we constructed a comprehensive cell atlas of the gill in the mussel from the South China Sea methane seeps (1100 m depth) using single-nucleus RNA-sequencing (snRNA-seq) and whole-mount in situ hybridisation.

The ultrastructural study on the female reproductive system of the beetle M. brevicauda (Mordellidae) confirmed the positive correlation between the length of the sperm and the size of the female seminal receptacle (Spermatheca). The spermatheca of the species is characterized by an apical bulb-like structure where the spermathecal duct forms numerous folds filled with sperm.

Objective: The principal delivery method for CRISPR-based genome editing in insects is now based on microinjection into single cells or embryos. The direct protein transduction systems cannot be employed in aphids because oogenesis occurs without apparent vitellogenesis. Given the limited timing of injection into the embryonic stage in oviparous aphids, a protein delivery system from the hemolymph to the germline and embryos would be a useful tool for genome editing.
