Streptomyces symbiont reaction to host NO defense
Reaction of the symbiotic Streptomyces philanthi versus free-living Streptomyces coelicolor to host produces nitric oxide. Experiments in vitro on solid grace agar cultures of S. philanthi and S.coelicolor exposed to N2 or 1% NO in N2, measured 2h or 6h, and S. philanthi after exposure to beewolf eggs emitting NO in vivo or controls without the egg present, measured 24h after egg laying.
