Nuclear receptors EcR-A/RXR and HR3 control early embryogenesis in the short-germ hemimetabolous insect Blattella germanica

iScience, 2023
Summary: The role of steroid hormone signaling during insect post-embryonic development has been extensively characterized. However, its function during embryonic development is less understood, particularly in short-germ band hemimetabolous insects.

Environmental influence on Pristionchus pacificus mouth form through different culture methods

Scientific Reports, 2017
Environmental cues can impact development to elicit distinct phenotypes in the adult. The consequences of phenotypic plasticity can have profound effects on morphology, life cycle, and behavior to increase the fitness of the organism.

Chromatin remodelling and antisense-mediated up-regulation of the developmental switch gene eud-1 control predatory feeding plasticity

Nature Communications, 2016
In the nematode Pristionchus pacificus, a developmental switch, the sulfatase eud-1, controls mouth-form plasticity. Here, the authors show that mutations in two conserved histone modifying enzymes mimic the eud-1 phenotype, in part mediated by an ...

Compression Fractures and Partial Phenotype Rescue With a Low Phosphorus Diet in the Chihuahua Zebrafish Osteogenesis Imperfecta Model

Frontiers in Endocrinology, 2022
Osteogenesis imperfecta (OI) is a group of heritable disorders affecting bone and other connective tissues. Dominant OI forms are mainly caused by mutations in collagen type I.

Adult Influence on Juvenile Phenotypes by Stage-Specific Pheromone Production

iScience, 2018
Summary: Many animal and plant species respond to population density by phenotypic plasticity. To investigate if specific age classes and/or cross-generational signaling affect density-dependent plasticity, we developed a dye-based method to ...

Beyond the whole-mount phenotype: high-resolution imaging in fluorescence-based applications on zebrafish

Biology Open, 2019
Zebrafish is now widely used in biomedical research as a model for human diseases, but the relevance of the model depends on a rigorous analysis of the phenotypes obtained.

Cells at the Edge: The Dentin–Bone Interface in Zebrafish Teeth

Frontiers in Physiology, 2021
Bone-producing osteoblasts and dentin-producing odontoblasts are closely related cell types, a result from their shared evolutionary history in the ancient dermal skeleton.

Notch signaling generates the “cut here line” on the cuticle of the puparium in Drosophila melanogaster

iScience, 2023
Summary: During a molt or eclosion, insects shed their cuticle, an extracellular matrix made by underlying epidermal cells, by cleavage along a defined line.

Evolutionary crossroads in developmental biology: amphioxus [PDF]

Development, 2011
The phylogenetic position of amphioxus, together with its relatively simple and evolutionarily conserved morphology and genome structure, has led to its use as a model for studies of vertebrate evolution. In particular, the recent development of technical approaches, as well as access to the complete amphioxus genome sequence, has provided the ...

Tachykinin-related peptides modulate immune-gene expression in the mealworm beetle Tenebrio molitor L.

Scientific Reports, 2022
Tachykinins (TKs) are a group of conserved neuropeptides. In insects, tachykinin-related peptides (TRPs) are important modulators of several functions such as nociception and lipid metabolism.
