Mutant sensory cilia in the nematode Caenorhabditis elegans
Eight classes of chemosensory neurons in C. elegans fill with fluorescein when living animals are placed in a dye solution. Fluorescein enters the neurons through their exposed sensory cilia. Mutations in 14 genes prevent dye uptake and disrupt chemosensory behaviors. Each of these genes affects the...

description | Eight classes of chemosensory neurons in
C. elegans fill with fluorescein when living animals are placed in a dye solution. Fluorescein enters the neurons through their exposed sensory cilia. Mutations in 14 genes prevent dye uptake and disrupt chemosensory behaviors. Each of these genes affects the ultrastructure of the chemosensory cilia or their accessory cells. In each case, the cilia are shorter or less exposed than normal, suggesting that dye contact is the principal factor under selection. Ten genes affect many or all of the sensory cilia in the head. The
daf-19 (m86) mutation eliminates all cilia, leaving only occasional centrioles in the dendrites. The cilia in
che-13 (e1805), osm-1 (p808), osm-5 (p813), and
osm-6 (p811) mutants have normal transition zones and severely shortened axonemes. Doublet-microtubules, attached to the membrane by Y links, assemble ectopically proximal to the cilia in these mutants. The amphid cilia in
che-11 (e1810) are irregular in diameter and contain dark ground material in the middle of the axonemes. Certain mechanocilia are also affected. The amphid cilia in
che-10 (e1809) apparently degenerate, leaving dendrites with bulb-shaped endings filled with dark ground material. The mechanocilia lack striated rootlets. Cilia defects have also been found in
che-2, che-3, and
daf-10 mutants. The
osm-3 (p802) mutation specifically eliminates the distal segment of the amphid cilia. Mutations in three genes affect sensillar support cells. The
che-12 (e1812) mutation eliminates matrix material normally secreted by the amphid sheath cell. The
che-14 (e1960) mutation disrupts the joining of the amphid sheath and socket cells to form the receptor channel. A similar defect has been observed in
daf-6 mutants. Four additional genes affect specific classes of ciliated sensory neurons. The
mec-1 and
mec-8 (e398) mutations disrupt the fasciculation of the amphid cilia. The
cat-6 (e1861) mutation disrupts the tubular bodies of the CEP mechanocilia. A cryophilic thermotaxis mutant,
ttx-1 (p767), lacks fingers on the AFD dendrite, suggesting this neuron is thermosensory. |
