Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Multiomics Reveal Associations Between CpG Methylation, Histone Modifications and Transcription in a Species That has Lost DNMT3, the Colorado Potato Beetle

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Despite lacking DNMT3, EM‐seq revealed CpG methylation in the Colorado potato beetle. CUT&Tag analysis showed an association of H3K36me3 and H3K27ac with transcription, with H3K36me3 mirroring CpG methylation, demonstrating epigenetic flexibility.

Ecological comparison of native (Apis mellifera mellifera) and hybrid (Buckfast) honeybee drones in southwestern Sweden indicates local adaptation.

PLoS ONE
Honeybee drones' only known task is to mate with a virgin queen. Apart from their mating behaviour, their ecology has been little studied, especially in comparison to honeybee females.

Wild bee toxicity data for pesticide risk assessments [PDF]

, 2019
Pollination services are vital for agriculture, food security and biodiversity. Although many insect species provide pollination services, honeybees are thought to be the major provider of this service to agriculture. However, the importance of wild bees

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

First Detection of Nosema ceranae, a Microsporidian Protozoa of European Honey­bees (Apis mellifera) In Iran [PDF]

Iranian Journal of Parasitology, 2011
Background: Nosemosis of European honey bee (Apis mellifera) is present in bee colonies world­wide. Until recently, Nosema apis had been regarded as the causative agent of the disease, that causes heavy economic losses in apicultures.

A comprehensive transcriptome data of normal and Nosema ceranae-stressed midguts of Apis mellifera ligustica workers

Data in Brief, 2019
Honeybees are pivotal pollinators of crops and wild flora, and of great importance in supporting critical ecosystem balance. Nosema ceranae, a unicellular fungal parasite that infects midgut epithelial cells of honeybees, can dramatically reduce honeybee

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...
