“…In crustaceans, NO/cGMP signaling plays a role in neuronal development and neuron, skeletal muscle and cardiac muscle regulation (Aonuma et al, 2000;Newland, 2001, 2002;Erxleben and Hermann, 2001;Hermann and Erxleben, 2001;Johansson and Mellon, 1998;Mahadevan et al, 2004;Scholz, 1999Scholz, , 2001Scholz et al, 1998Scholz et al, , 2001. NOS is expressed in neurons of the cerebral, stomatogastric, eyestalk, abdominal terminal and cardiac ganglia (Christie et al, 2003;Johansson and Carlberg, 1994;Johansson and Mellon, 1998;Lee et al, 2000;Scholz et al, 2002;Schuppe et al, 2001aSchuppe et al, ,b, 2002Talavera et al, 1995;Zou et al, 2002).…”
