TGF beta dauer pathway read out

Does anyone know of a gene or reporter strain that is regulated by the daf-7 (TGF beta) dauer pathway? I wished to test a gene that is known to be downstream of the TGFbeta dauer pathway with loss of my gene of intesrest.
Thank you

I suspect there are other, more recently developed reagents - but have you looked at Thatcher, Haun, and Okkema?
