npr-1 is necessary and sufficient in RMG to promote
srh-234 expression. A strong reduction was found in
srh-234 expression in ADL in lf mutants of
npr-1 (alleles
ad609,
ky13 and
ok1447), and in a reduction-of-function
npr-1 allele,
g320, in fed conditions, with the
g320 allele having the weakest effect.
