چکیده

The nucleotide sequence of tRNA1Gly isolated from the posterior silk gland of Bombyx mori has been determined. This transfer RNA is present in high amounts in the posterior silk gland during the fifth larval instar. It has a GCC anticodon, capable of decoding a major glycine codon in the fibroin messenger RNA, GGU. Structural features of Bombyx tRNA1Gly and its homology to other eukaryotic glycine tRNAs are discussed.

Alteration in the primary metabolites in three different tissues of silkworm, Bombyx mori L. under the influence of a Juvenoid, R394

A bivoltine silkworm hybrid, KA x NB4D2 was treated with the juvenoid R394 (Ethyl-9 cyclohexyl-3,7-dimethyl-2,4-nonadienoate) at a dose of 0.039 nl/larva at 24, 48, 72 and 96 h of 5th instar for silk yield improvement. Treatment specific significant increase was observed in the cocoon and shell weight with no such marked variation in the shell percentage. Notable changes were also seen in tr...

Circular transcriptome sequencing of the middle silk gland and posterior silk gland in the Bombyx mori

Circular transcriptome sequencing of the middle silk gland (MSG) and posterior silk gland (PSG) in the Bombyx mori are presented. The middle silk gland and posterior silk gland were collected from the third day of fifth-instar B.mori larvae. The circular RNAs enriched by using RNase R to degrade the linear RNA molecules, and circular RNA sequencing (circRNA-seq) was performed using an Illumina ...

Clone and functional analysis of Seryl-tRNA synthetase and Tyrosyl-tRNA synthetase from silkworm, Bombyx mori

Aminoacyl-tRNA synthetases are the key enzymes for protein synthesis. Glycine, alanine, serine and tyrosine are the major amino acids composing fibroin of silkworm. Among them, the genes of alanyl-tRNA synthetase (AlaRS) and glycyl-tRNA synthetase (GlyRS) have been cloned. In this study, the seryl-tRNA synthetase (SerRS) and tyrosyl-tRNA synthetase (TyrRS) genes from silkworm were cloned. Their...
