The developmental profiles of
Cbr-puf-2 and
Cbr-puf-1.2 mRNA levels are qualitatively similar and are typical of germ line-expressed genes: low expression from embryo to L2 stages, slightly increasing expression at L3 and L4, and peak levels in adults. However,
Cbr-puf-2 is over 100-fold more abundant than
Cbr-puf-1.2.
