ED Fig.10: Homeobox codes define neuronal subclasses.

(a) Homeobox codes subdivide neuron classes in the head. Pictures of head neuron classes are provided from WormAtlas.org. Homeobox genes expressed in each neuron are listed. Yellow color indicates the homeobox gene is expressed in all members of that neuron class. Orange and green colors indicate that the homeobox gene is expressed in only a subset of neuron class members.

(b) Tabular representation of homeobox gene expression subdividing members of the ventral nerve cord motor neurons. Red and blue boxes correspond to cholinergic and GABAergic neurotransmitter identity, respectively. Green boxes indicate the gene is a member of the HOX subfamily, gray boxes indicate that a gene is expressed in some neurons of the VNC, black boxes indicate that a gene is expressed in all neurons of the VNC.
