Additional file 4 of Stage-specific expression of an odorant receptor underlies olfactory behavioral plasticity in Spodoptera littoralis larvae

Additional file 4: Figure S1. RT-PCR gel images of PCR-amplified ORs at different developmental stages of Spodoptera littoralis. Comparison included negative-control (control), first instar heads (Slit_1), fourth instar heads (Slit_4), male antennae (Slit_���) and female antennae (Slit_���) with 1kb gene ruler ladder (Thermo Fischer Scientific). Red rectangles around SlitOR4 and SlitOR40 represent differential expression in the first and fourth instar, respectively, supported by RT-PCR and transcriptomic analysis.
