Gut bacterial communities assist host animals with numerous functions such as food digestion, nutritional provision, or immunity. Some social mammals and insects are unique in that their gut microbial communities are stable among individuals. In this

Integrative and conjugative elements (ICEs) are widespread mobile DNA elements in the prokaryotic world. ICEs are usually retained within the bacterial chromosome, but can be excised and transferred from a donor to a new recipient cell, even of anoth

Social insects frequently engage in oral fluid exchange – trophallaxis – between adults, and between adults and larvae. Although trophallaxis is widely considered a food-sharing mechanism, we hypothesized that endogenous components of this fluid

Significance Inotocin, the oxytocin/vasopressin-like peptide, is widely conserved in arthropods; however, little is known about its molecular function. Here, we show that, in ants, the expression levels of inotocin and its receptor are correlated wit

Dynamics of bacterial cell proliferation inhibited by specific proteins for effective horizontal transmission of the integrative and conjugative element ICEclc

Autor: Akiko Koto, Ryo Miyazaki, Sotaro Takano

The integrative and conjugative element ICEclc, a prevalent mobile element in proteobacteria, is one of the experimental models for horizontal gene transfer. ICEclc is usually retained in a bacterial chromosome, but can be excised and transferred fro
