Bacterial Bioluminescence Regulates Expression of a Host Cryptochrome Gene in the Squid-Vibrio Symbiosis
ABSTRACT The symbiosis between the squid Euprymna scolopes and its luminous symbiont, Vibrio fischeri, is characterized by daily transcriptional nucleus ball toy rhythms in both partners and daily fluctuations in symbiont luminescence.In this study, we sought to determine whether symbionts affect host transcriptional rhythms.We identified two trans
