Developmental profile of apoLTP-II/I (A) and apoLTP-III (B) gene expression. Total RNA was prepared from the fat body of fourth and fifth instar larvae, pupae, and adults. Quantification of transcripts was carried out by qPCR. The y-axis (relative amount) indicates the fold-increase in mRNA expression compared with that of fourth instar larvae at day 0 (L4-0). The y-axis bars on L4-0 in both (A) and (B) are set to one. Results shown are the mean ± SEM (n = 3). Stages are shown as L4, fourth instar larval stage; L5, fifth instar larval stage; S, spinning cocoon stage; P, pupal stage; A, adult stage.
