Terminology and the Fundamentals of Classification of Light-induced Behaviour in Freely Motile Microorganisms

Zusammenfassung

The problems concerning terminology and classification of the phenomena associated with the motile properties of microorganisms have been studied by a number of researchers [Halldal,1958; Jahn and Bovee, 1968; Nultsch, 1973, 1975, 1980; Diehn et al., 1977; Feinleib, 1977, 1978, 1980; Lenci and Colombetti, 1978; Diehn, 1979; Häder, 1979, 1987a, 1987b, 1987c, 1996a, 1996b; Nultsch and Häder, 1979; Posudin, 1982, 1985; Sineschekov and Litvin, 1982; Colombetti and Lenci, 1982; Colombetti et al., 1982; Lenci, 1982; Haupt, 1983; Burr, 1984; Lenci et al., 1984; Burr, 1984; Posudin et al., 1988, 1990, 1991, 1992a, 1992b, 1993, 1995, 1996a,b,c; Massjuk et al.,1988; Massjuk and Posudin,1991a; Kawai and Kreimer, 1992; Witman, 1994; Kreimer, 1994; Martynenko et al., 1996; Posudin and Massjuk, 1996; Lenci et al., 1997; Hegemann and Harz, 1998; Sineschekov and Govorunova, 1999; Lebert and Häder, 2000; Gualtieri, 2001; Häder and Lebert, 2001; Hegemann and Fisher, 2001; Hegemann et al., 2001; Massjuk and Posudin, 2002]. The definition of terms and concepts, however, remains unacceptably ambiguous. On occasion a new meaning is attached to an old term, e.g., “phototaxis” or “photokinesis” which is interpreted differently by various authors (e.g., compare Diehn et al., 1977; Nultsch and Häder, 1979). Likewise, terms with different meanings are used as synonyms (e.g. “behavioural light response”, “behavioural response”, “light controlled cell motility”, “light controlled movement”, “light response”, “light-induced behavioural response”, “light-induced responses of freely moving organisms”, “locomotive and motile response”, “motile behaviour”, “motile response to light”, “movement behaviour”, “photobehaviour”, “photobehaviour response”, “photoinduced behaviour”, “photomotile response”, “photomotion”, “photomovement response”, “photomovement”, “photoreaction”, “photoregulation of movement”, “photoresponse”) – see Posudin, 1982, 1985; Sineschekov and Litvin, 1982; Wayne, 1991; Kreimer, 1994; Hegemann, 1997; Holland et al., 1997; Matsuda, 1998; Horigushi et al., 1999; Sineschekov, Govorunova, 1999; Lebert and Häder, 2000; Govorunova et al., 2000, 2001; Haupt, 2001; Häder and Lebert, 2001; Tahedl and Häder, 2001.
