Since a nondirectional response is not a true taxis, I have proposed that the term “photophobic response” be used instead of “phobophototaxis” (Diehn, 1969 a, 1970 a), and will adhere to that terminology throughout this presentation.

How do bacteria detect the attractants? How is this sensed information translated into action; that

Phototaxis in , 1: Physiological Basis of Photoreception and Tactic Orientatione description of phototaxis defines it as orientation and subsequent oriented movement of freely motile organisms in response to light — towards the light in the case of positive, and away from it in the case of negative phototaxis. While in the past, some authors have distinguished between “topo-ph
