Figure 1.

Relative expression levels of the NPF and NPFR transcripts at different developmental stages (A) and in different body parts (B) of Acyrthosiphon pisum. For each sample, the transcript level was measured via qRT-PCR and normalized against RPL7. The data were statistically analyzed by one-way ANOVA followed by Duncan's multiple-range test. Different lowercase letters indicate significant differences at the 0.05 level.
