Fig. 3. The forkhead transcription factor UNC-130 is required for appropriate
repression of lag-2 expression during reproductive development.
(A) Expression in the head region of the various forkhead transcription
factors predicted from the C. elegans genome database during the
dauer stage in daf-7(e1372) mutants (Hope et al., 2004). (B)
Confocal images depicting the expression of the UNC-130::RFP translational
fusion protein in the daf-2(e1370); qIs56
(lag-2::GFP) background, and the merge of the two channels during the
dauer stage. (C) The percentage of L3 larvae kept at sub-threshold
temperature (20°C) that express lag-2::GFP in the IL2 neurons in
the mutant background is indicated.
