Faithful allies since the CretaceousMunich, Germany (SPX) Apr 17, 2014 Like humans, many animals depend on beneficial microbes for survival. Although such symbioses can persist for millions of years, the factors maintaining their long-term stability remain, in most cases, unknown. Scientists from the Max Planck Institute for Chemical Ecology and the University of Regensburg, in collaboration with researchers in the USA, now discovered that certain wasps tightly control mother-to-offspring transmission of their bacterial symbionts. This stabilizes the symbiotic allian ... read more |
