Gut bacteria and pheromones

Excerpt:

… their study highlights the previously overlooked effect of gut flora in communication among insects. Next, they plan to investigate whether gut bacteria contribute to the development of scent profiles that are unique within a particular colony of cockroaches.”

My comment: Gut microbes link the metabolic networks and genetic networks of all vertebrates and invertebrates to their morphological and behavioral phenotypes in the context of well-detailed models that link atoms to ecosystems via the nutrient-dependent pheromone-controlled physiology of reproduction.

Conserved molecular mechanisms of nutrient-dependent pheromone-controlled RNA-mediated cell type differentiation link the bioluminescent gut microbes of squid to symbiotic interactions in all living genera.

Overlooking the influence of gut bacteria is like overlooking the influence of food odors on foraging and the fact that “Feedback loops link odor and pheromone signaling with reproduction” in species from microbes to humans.
