Transcriptomic analysis of Bombyx mori corpora allata with comparison to prothoracic glands in the final instar larvae.

The corpus allatum (CA) is an endocrine organ of insects that synthesizes juvenile hormone (JH). Yet little is known regarding the global gene expression profile for the CA, although JH signaling pathway has been well-studied in insects. Here, we report the availability of the transcriptome resource of the isolated CA from the final (fifth) instar larvae of the silkworm, Bombyx mori when the JH titer is low.

Transcriptomic analysis of the prothoracic gland from two lepidopteran insects, domesticated silkmoth Bombyx mori and wild silkmoth Antheraea pernyi.

The prothoracic gland (PG) is an important endocrine organ of synthesis and secretion of ecdysteroids that play critical roles in insects. Here, we used a comparative transcriptomic approach to characterize some common features of PGs from two lepidopteran species Bombyx mori and Antheraea pernyi. Functional and pathway annotations revealed an overall similarity in gene profile between the two PG transcriptomes.

Comparative mitochondrial genomes provide new insights into the true wild progenitor and origin of domestic silkworm Bombyx mori.

The domestication of domestic silkworm Bombyx mori, the only truly domesticated insect, is a distinctive event in agricultural history. The domestication and origin of domestic silkworm remains unclear, although it has connected with human for ~5500 years. In the present study, we would like to highlight our evidence from whole mitochondrial genome for the presence of two genetically distinctive subtypes in Chinese B.

The Complete Mitochondrial Genome of the Longhorn Beetle Dorysthenes paradoxus (Coleoptera: Cerambycidae: Prionini) and the Implication for the Phylogenetic Relationships of the Cerambycidae Species.

The longhorn beetle Dorysthenes paradoxus (Faldermann, 1833) (Coleoptera: Cerambycidae) is not only a serious agricultural pest but also a traditionally edible insect in China. However, no genetic information on this species has been acquired. In the present study, we report the mitochondrial genome (mitogenome) of Do.
