Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Downregulation of BmSTAT transcription factor promoted nucleopolyhedrovirus replication in Bombyx mori

Frontiers in Microbiology
The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway plays a crucial role in the viral immune processes of organisms, with STAT being a key transcription factor downstream in this pathway. The STAT gene of Bombyx

New Evidence for Early Silk in the Indus Civilization [PDF]

, 2008
Silk is an important economic fiber, and is generally considered to have been the exclusive cultural heritage of China. Silk weaving is evident from the Shang period, though the earliest evidence for silk textiles in ancient China dates to more than a ...

Neuromuscular systems in the fifth instar larva of silkworm Bombyx mori (Lepidoptera: Bombycidae): II- Abdominal musculature and its innervation [PDF]

, 2009
The gross organisation of abdominal musculature and its innervation by segmental ganglionic nerves were studied in the fifth instar larva of Bombyx mori. The musculature comprises dorsal, ventral and lateral groups of muscles, represented as external and

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

Insect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

N6-Methyladenosine Level in Silkworm Midgut/Ovary Cell Line Is Associated With Bombyx mori Nucleopolyhedrovirus Infection

Frontiers in Microbiology, 2020
Bombyx mori nucleopolyhedrovirus (BmNPV) is one of the most serious pathogens in sericulture and causes huge economic loss annually. The roles of N6-methyladenosine (m6A) modification in silkworms following BmNPV infection are currently unclear.

Energetics of pupal-adult metamorphosis in the silkworm, Bombyx mori : An analysis of transdeamination parameters in the fat body and haemolymph [PDF]

, 2018
Transdeamination seems to be an important alternative energy-intensive gluconeogenesis mechanism that generates glucose from non-carbohydrate sources during pupal-adult metamorphosis in Bombyx mori. Studies on four transdeamination parameters, viz., free

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

Insect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Photoperiod-modulated instar-specific clock-shifting in the circadian protein and amino acid rhythms in the larval segmental muscle of Bombyx mori [PDF]

, 2011
The photoperiod-modulated clock-shifting in the circadian protein rhythm was studied in the segmental muscle of Bombyx mori. The analysis of phase response curves of the fourth instar rhythm revealed that the muscle tissue completes six protein synthetic

The plasticisation model of dye diffusion: Part 8

Coloration Technology, EarlyView.
Abstract Re‐evaluation using the Williams–Landel–Ferry equation, of exhaustion/rate of dyeing/fixation data previously reported for and acid dye, natural dye and two reactive dyes on three different types of silk substrate revealed that thermally activated dye diffusivity is governed by the thermally regulated structural relaxation times of the ...
