Table 3 The presence of Fib-H, Fib-L,fibrohexamerin, p25 and sericin genes in 5
lepidopteran genomes.
The numbers in the column of S. ricini and B. mori stand
for copy number of each genes. The accession numbers in the column ofP. xuthus were derived from the transcripts of the corresponding
genes, registered at Genbank. Circles in the columns of P.
xylostella and D. plexippus indicate that genome assembly of
each species has at least one genomic region showing high similarity to
the B. mori silk proteins with an e-value less than 1e-5.
Question marks means BLAST search failed to identify any region with
high similarity.

Amount (bp; A) and proportion (%; B) of repetitive sequences in five
lepidopteran species, including S. ricini , B. mori ,D. plexippus , P. xuthus and P. xylostella .
Fig 3. Comparison between S. ricini and B.
mori genome
(A) Left side of ideogram represents chromosomes of B. mori and
right side represents scaffolds of S. ricini . ‘bm_1’ to ‘bm_28’
corresponds to the chromosomes of B. mori . As for S.
ricini , 35 scaffolds, ‘Sr_HGAP_ JL_scaf_1 (sr_1)’ to ‘Sr_HGAP_
JL_scaf_35 (sr_35)’ are shown. Outer ring (black) indicates putative
chromosomes of S. ricini . The chromosome numbers of S.
ricini are given according to Yoshido et al. (2011).
(B) Venn diagram of protein orthogroups in five lepidopteran species.
Number in each section indicates the number of orthogroups.
(C) Phylogenetic tree of five lepidopteran species based on alignments
of 3,907 single copy orthologs. Plutella xylostella was used as
the outgroup for rooting the tree. Bootstrap values are shown on the
branches.
(D) Phylogenetic tree of S. ricini chorion proteins (SrCho),B. mori chorion proteins (BmCho), P. xylostella chorion proteins
(PxyCho), P. xuthus chorion proteins (PxuCho) and D.
plexippus chorion proteins (DpCho). Branch colors are: Red– BmCho;
Blue–SrCho; Purple–PxyCho; Green–PxuCho; Orange–DpCho.
