Characterization of the C -glycosyl flavones in Pr1 and pr1 silks. (A) HPLC chromatograms of silk methanolic extracts from Pr1 and pr1 silks measured at 340 nm. Maysin, apimaysin, and rhamnosylisoorientin elute at approximately 22 min, 23.5 min, and 16 min, respectively. (B) Maysin, apimaysin, and rhamnosylisoorientin levels in silks of homozygous pr1; P1-wr, Pr1; P1-wr, pr1; P1-rr, Pr1; P1-rr, pr1; p-del2, Pr1; p-del2, pr1; P1-ww, and Pr1; P1-ww were determined by HPLC analysis. All data are presented as mean of ten biological replicates. (C) Mean corn earworm larval weight and days to pupation on fresh silk from pr1; P1-wr, Pr1; P1-wr, pr1; P1-rr, Pr1; P1-rr, pr1; p-del2, Pr1; p-del2, pr1; P1-ww, and Pr1; P1-ww lines.
