Synthetic dauer-constitutive phenotype of flr-1

Genotype	Percentage dauer larvae (n)*
flr-1(ut11) unc-3(el51)	63%  (347)
flr-1(ut11) unc-3(cn4146)	40%  (446)
flr-1(ut1) unc-3(el51)	46%  (180)
flr-1(ut1) unc-3(cn4146)	49%  (284)
flr-2(ut5); unc-3(el51)	5%  (301)
flr-5(ut73); unc-3(el51)	2%  (808)
flr-2(ut5); flr-1(ut11) unc-3(el51)	0%  (236)
flr-5(ut73); flr-1(ut11) unc-3(el51)	3%  (256)

Shown is the percentage of dauer larvae produced at 20°C under non-dauer-forming conditions, i.e., plenty of food and sparse population. All of the flr-1 unc-3 strains produced fewer dauer larvae (5–19%) at 25°C than 20°C. Wild-type animals, all the single-mutants except unc-3(cn4146), and the double mutants flr-2; flr-1 and flr-5; flr-1 produced less than 1% dauer larvae (n > 100), while unc-3(cn4146) produced 8% dauer larvae (n = 218).
