| Subcellular_localization | DYF-6::GFP was also expressed in the cell and dendritic bodies of the phasmid neurons in the six dauer larvae (the dendritic bodies were often kinked, as though their linearity had been affected by shrinkage of the body during formation of the dauer state). In four of the animals, DYF-6::GFP indicated that the phasmid neurons had proper dendritic endings, and IFT of the GFP could be easily seen in the endings. In the other two animals, however, DYF-6::GFP did not provide evidence for the existence of dendritic endings for the phasmid neurons, indicating that the endings might occasionally be severely retracted or modified in dauer larvae. | |||
| For both the amphid and phasmid neurons, the greatest intensity of DYF-6::GFP was in the transition zone between the dendritic bodies and their ciliary endings. Of particular note, anterograde and, to a lesser extent, retrograde movement of GFP particles could be seen along the length of the dendritic endings of both the amphid and phasmid neurons. In the amphid neurons, the particles moved in the anterograde direction over the combined middle and distal segments of the ciliary axoneme at 0.9 +/- 0.1 m/sec. IFT could be seen prior to hatching and throughout postembryonic development and adulthood. | ||||
| IFT of DYF-6::GFP in dauer larvae: Six dauer larvae from SP2730 were picked from plates exhausted of bacteria to NGM plates without bacteria, followed by a further incubation of 3 days. DYF-6::GFP was expressed in the cell bodies and in the dendritic bodies and endings of the dye-filling amphid neurons. Moreover, IFT could be easily seen in the dendritic endings, but there appeared to be fewer GFP particles undergoing IFT in the amphid bundles relative to that seen in non-dauer animals. | ||||

| Pattern | Expression of DYF-6::GFP is restricted to a few cells from hatching to adulthood. Of particular note, DYF-6::GFP is consistently expressed in the cell bodies, dendritic bodies, and dendritic endings of the phasmid neurons. Expression was also very evident in the dendritic bodies and endings of the amphid sensilla. DYF-6::GFP was faintly and irregularly expressed in the cell bodies of the dye-filling amphid neurons. Expression of DYF-6::GFP was also seen in the hypodermis and in several neuronal cell bodies in the region of the inner labial cell bodies. Finally, expression can be seen in a lateral neuronal cell body in the region of the PDE cell body in older larvae and adults. | |||
