Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Microarray analysis of a salamander hopeful monster reveals transcriptional signatures of paedomorphic brain development

BMC Evolutionary Biology, 2010
Background The Mexican axolotl (Ambystoma mexicanum) is considered a hopeful monster because it exhibits an adaptive and derived mode of development - paedomorphosis - that has evolved rapidly and independently among tiger salamanders.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

GameXPeptide synergistically enhances the control efficiency of Metarhizium anisopliae by inhibiting cotton aphid immunity

New Plant Protection, EarlyView.
In this research, GXP serves as a potent synergist for Metarhizium anisopliae in controlling cotton aphids. Its synergistic effect is achieved through two key mechanisms: first, by downregulating melanization protease 1 expression to inhibit phenoloxidase activity, thereby suppressing melanization; second, by reducing hypoxanthine levels, which ...

Diversity of Insect Sesquiterpenoid Regulation

Frontiers in Genetics, 2020
Insects are arguably the most successful group of animals in the world in terms of both species numbers and diverse habitats. The sesquiterpenoids juvenile hormone, methyl farnesoate, and farnesoic acid are well known to regulate metamorphosis ...

Plant and insect functional traits influence herbivore performance under climate change

Oikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

Investigating the impact of estetrol and 17α-ethinylestradiol on thyroid hormonal signaling during zebrafish (Danio rerio) metamorphosis

Ecotoxicology and Environmental Safety
The thyroid axis orchestrates key biological functions in fish, including metamorphosis. Disruption of thyroid signaling by endocrine disrupting compounds (EDCs), particularly estrogens, remains understudied during this sensitive period.

Peptidic product derived from trypsin autolysis modulates insect digestive proteases and supports plant biochemical defense

Pest Management Science, EarlyView.
XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...

Comprehensive assessment of chemical and microbial inducers for coral larval settlement across diverse coral species

Frontiers in Marine Science
IntroductionCoral restoration efforts increasingly focus on enhancing larval settlement and post-settlement survival. However, the species-specific efficacy of different settlement inducers remains inadequately understood, limiting optimization of ...
