Skeletal Muscles Do Not Undergo Apoptosis During Either Atrophy or Programmed Cell Death-Revisiting the Myonuclear Domain Hypothesis

Frontiers in Physiology, 2019
Skeletal muscles are the largest cells in the body and are one of the few syncytial ones. There is a longstanding belief that a given nucleus controls a defined volume of cytoplasm, so when a muscle grows (hypertrophy) or shrinks (atrophy), the number of

Waterlogging stress disarms nicotine‐mediated defense to herbivores through the bHLH1‐ERF1 transcriptional switch

The Plant Journal, Volume 128, Issue 3, November 2026.
SUMMARY Waterlogging stress reduces root jasmonic acid levels, downregulating the NbbHLH1‐NbERF1 signaling module. This suppression diminishes the expression of key biosynthetic genes (NbPMT and NbQPRT), leading to decreased nicotine accumulation in the leaves and increased susceptibility to chewing herbivores.

Spatial Representation of Feeding and Oviposition Odors in the Brain of a Hawkmoth

Cell Reports, 2018
Summary: Female hawkmoths, Manduca sexta, use olfactory cues to locate nectar sources and oviposition sites. We investigated if the behavioral significance of odorants is represented already in the antennal lobe, the first olfactory neuropil of the ...

A Tale of Two States: Similarities and Differences in Neuropeptide Signaling in Larval and Adult Drosophila

Journal of Comparative Neurology, Volume 534, Issue 10, October 2026.
Neurosecretory cells of the brain are mostly the same in larvae and adults of Drosophila melanogaster and they produce the same neuropeptides and peptide hormones (NPHs), yet their functional roles differ to a large extent between the two stages. Many other peptidergic neurons change both in numbers and function.

The potassium impermeable apical membrane of insect epithelia: a target for development of safe pesticides

Memorias do Instituto Oswaldo Cruz, 1987
Columnar cell apical membranes (CCAM) in series with goblet cell apical membranes (GCAM) form an electroosmotic barrier separating the midgut lumen from epithelial cell cytoplasm.

The oxygen and pressure physiology of upper elevational range limits in insects

Functional Ecology, Volume 40, Issue 10, Page 3020-3033, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is widely expected to cause montane insects to shift upslope, and there is good evidence that some populations are doing so. Nevertheless, patterns are mixed—with evidence supporting upslope, downslope or even no movement of both lower and upper range ...

Sex-specific odorant receptors of the Tobacco Hornworm Manduca sexta

Frontiers in Cellular Neuroscience, 2010
As odor information plays a vital role in the life of moths, their olfactory sense has evolved into a highly specific and sensitive apparatus relevant to reproduction and survival.

Extensive conserved synteny of genes between the karyotypes of Manduca sexta and Bombyx mori revealed by BAC-FISH mapping. [PDF]

PLoS ONE, 2009
BACKGROUND: Genome sequencing projects have been completed for several species representing four highly diverged holometabolous insect orders, Diptera, Hymenoptera, Coleoptera, and Lepidoptera. The striking evolutionary diversity of insects argues a need

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, Volume 33, Issue 5, Page 1845-1864, October 2026.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Paving the Way for Plant‐Based Bioproduction of (Z)‐13‐Octadecenoic Moth Pheromone Compounds

Plant Biotechnology Journal, Volume 24, Issue 10, Page 5554-5569, October 2026.
ABSTRACT Sex pheromones are eco‐friendly agents to control pest insects. Yet, the cost of synthetic pheromone production has restricted their use essentially to high value crops. Plant‐based bioproduction of pheromone compounds offers a promising and sustainable alternative, opening up for the deployment of pheromone‐mediated pest control also in row ...
