Lateral gene transfer enables chemical protection of beetles against antagonistic fungi
Like all other living organisms, animals face the challenge of fending off enemies. Using chemical weaponry can be an effective strategy to stay alive. Instead of taking over this task themselves, many marine and terrestrial animals associate with microbial symbionts that can provide such protection. An international team of researchers led by scientists of Johannes Gutenberg University Mainz (JGU) and the Leibniz Institute for Natural Product Research and Infection Biology in Jena has discovered that bacteria associated to Lagria villosa beetles can produce an antifungal substance very similar to one found in tunicates living in the marine environment. The researchers revealed that this commonality is likely explained by the transfer of genes between unrelated microorganisms.
