Semi-quantitative RT-PCR amplification of total RNA with BmSPI-specific oligonucleotides. Te, testis; Ov, ovary; He, head; Fa, fat body; In, integument; Mi, midgut; Ha, haemocyte; Ma, Malpighian tubules; Si, silk gland. The silkworm cytoplasmic actin A3 gene (Bmactin3, GenBank accession No. U49854) was used as internal control, and denoted by Bmactin3.
