title: De novo genome assembly of the bagworm species Eumeta crameri
organism: Eumeta cramerii
description: Bagworms are commonly known for the well-organized case or bag surrounding them constructed using their silk and plant materials. To understand the genetic basis of these unique characteristics in bagworms, we performed multi-omics analyses of a bagworm species, Eumeta crameri. The genome and transcriptome sequencing of E. crameri were used to construct the nuclear genome with a size of 668.2 Mb, N50 value of 6.6 Mb, and 13,554 coding genes, which was further assembled into 31 pseudochromosomes. The mitochondrial genome had a size of 15.6 Kb. We established the phylogenetic position of E. crameri with respect to 54 other insect species. The comparative analyses of E. crameri with other Lepidopterans revealed the adaptive evolution of genes related to primary metabolic pathways, defense, molting and metamorphosis, and silk formation in the bagworm species. We also showed the ultrafine nature of the E. crameri silk fibers. Further, we performed the gut microbiome sequencing for E. crameri and constructed a gut microbial gene catalog, which revealed the unique composition of the gut microbiome and its significance for host metabolism and defense. Together, the results provide multi-faceted insights into the biological processes that support the well-organized holometabolous metamorphosis inside the bags of E. crameri.
