Since a plant miRNA (miR168) cross-regulating a mammalian transcript was reported, miRNA-mediated cross-kingdom communication has become one of the most compelling but controversial topics. In the present study, we used silkworm and mulberry, which is a model for studies on the interactions between the insect and its host plant, to address whether miRNA-mediated cross-kingdom communication is a...

Although the photoperiodic reactions of insects and mites have been studied quite extensively (Lees, 1955; de Wilde, 1962), the site of the photoreceptors is still unknown. The light pathway does not seem to involve the eyes. Thus Tanaka (1950) observed that the photoperiodic control of diapause in the silkworm Antheraea pernyi was not affected by cauterizing the lateral ocelli of the 4th-insta...

The silkworm, Bombyx mori, uses a complex olfactory system to determine whether the food is edible. As an odor degrading enzyme, UDP-glycosyltransferase (UGT) participates in degradation of molecules silkworm. By sequencing whole genome silkworm NB and using comparative genomics methods, we found that UGT46A1 unique species eat mulberry leaves. Bioinformatics shows its function may be related f...

The Study was carried out at Department of Sericulture, UAS, GKVK, Bengaluru under irrigated condition during the 2020-21 to study effect soil application liquid organic manures in mulberry and its on larval cocoon traits silkworm, V-1 variety planted 90+150 × 60 cm spacing. Three different were tested against recommended dose fertilizer (control), leaf quality assessed via feeding silkworm. Si...

The domesticated silkworm, Bombyx mori serves as an ideal representative of lepidopteran species for a variety of scientific studies. As a result, databases have been created to organize information pertaining to the silkworm genome that is subject to constant updating. Of these, four main databases are important for store nucleotide information in the form of genomic data, ESTs and microsateli...

Establishment of efficient genome editing tools is essential for fundamental research, genetic engineering, and gene therapy. Successful construction and application of transcription activator-like effector nucleases (TALENs) in several organisms herald an exciting new era for genome editing. We describe the production of two active TALENs and their successful application in the targeted mutage...

Nuclear polyhedrosis, that is jaundice, is distinguished among other mulberry silkworm diseases by its pathogenicity. It is a powerful viral, hereditary disease of mulberry silkworm that results in mass destruction of mulberry silkworm. Polyhedrose is spread in all silk manufacturer countries and incurs the losses to sericulture more than any infectious diseases of mulberry silkworm. Viruses wh...

Ganciclovir, foscarnet, vidarabine and ribavirin, which are used to treat viral infections in humans, inhibited the proliferation of a baculovirus (Bombyx mori nucleopolyhedrovirus) in BmN4 cells, a cultured silkworm cell line. These antiviral agents inhibited the proliferation of baculovirus in silkworm body fluid and had therapeutic effects. Using the silkworm infection model, the antiviral a...

The present study has been aimed at examining severe perturbations in the Cholinergic system in different tissues like Silk Gland, Hemolymph, Fat body and Muscle of silkworm larvae treated with Zinc, vitamin, Pyridoxine and hormone, Methoprene. The experimental worms were divided in to four groups and fed with mulberry leaves soaked in the selected compounds i.e. Zinc chloride, Pyridoxine, Meth...
