Heat map of Stringent QT (quality threshold) clustering, the sequence BLAST results and the organization of the NPLP genes. A: Amino acid sequence BLAST analysis of Bombyx mori theoretical NPLPs (accession number: HQ386680-HQ386685) with those sequences from Sarcophaga Crassipalpis NPLP4 (accession number: EU526381.1), Drosophila Melanogaster NPLP4 (accession number: NM_144095.1). Amino acids conserved in NPLP are highlighted in dark and light gray. *. B: Genomic organization of NPLP genes. Triangles correspond to the exons. Arrows indicate transcriptional direction. Nscaf: Scaffold data assembled by Japanese and Chinese groups. C: Heat map of Stringent QT (quality threshold) clustering of six expressed NPLP genes. Clustering was done using Mev software and was displayed by rainbow scheme. The colors in the map display the relative values of all tiles within four selected developmental stages; Blue indicates the lowest expression and red indicates the highest expression. The numerical values give the actual values on a log 2 scale, which are associated with each color. The color scale bar is shown at the top corner of the figure. The names of genes are indicated.
