    ..These results suggest that daf-11 is directly involved in chemosensory transduction essential for dauer formation, while the other Daf-c genes play roles downstream of the chemosensory step. ..

    ..The EGL-4 cGMP-dependent protein kinase functions downstream of insulin and TGF-beta in sensory neurons including ASI to control quiescence in response to food intake. ..

    ..Hence, the daf-1 product appears to be a cell-surface receptor required for transduction of environmental signals into an appropriate developmental response. ..

    ..These mutations appear to indirectly result in a ts phenotype by enhancing the expression of a wild-type ts developmental process. ..
  5. Thatcher J, Haun C, Okkema P. The DAF-3 Smad binds DNA and represses gene expression in the Caenorhabditis elegans pharynx. Development. 1999;126:97-107 pubmed
    ..We have examined expression of this gfp reporter in dauer larvae and have observed no daf-3-dependent repression of C activity. These results suggest daf-3 directly regulates pharyngeal gene expression during non-dauer development. ..
  6. Inoue T, Thomas J. Targets of TGF-beta signaling in Caenorhabditis elegans dauer formation. Dev Biol. 2000;217:192-204 pubmed
    ..Instead, these experiments suggest the nervous system as a target of DAF-7 signaling and that the nervous system in turn regulates dauer formation by other tissues. ..

  8. Gunther C, Georgi L, Riddle D. A Caenorhabditis elegans type I TGF beta receptor can function in the absence of type II kinase to promote larval development. Development. 2000;127:3337-47 pubmed
    ..Signaling from a strong DAF-1/DAF-4 receptor complex or a weaker DAF-1 receptor alone may provide larvae with more precise control of the dauer/nondauer decision in a range of environmental conditions. ..
  9. Shaw W, Luo S, Landis J, Ashraf J, Murphy C. The C. elegans TGF-beta Dauer pathway regulates longevity via insulin signaling. Curr Biol. 2007;17:1635-45 pubmed
    ..Together, our results suggest there are TGF-beta-specific downstream targets and functions, but that the TGF-beta and IIS pathways might be more tightly linked in the regulation of longevity than has been previously appreciated. ..
