The evolution of insects has been marked by the appearance of key body plan innovations that promoted the outstanding ability of this lineage to adapt to new habitats, boosting the most successful radiation in animals. To understand the evolution of these new structures, it is essential to investigate which are the genes and gene regulatory networks participating during the embryonic development of insects. Great efforts have been made to fully understand gene expression and gene regulation during the development of holometabolous insects, in particular Drosophila melanogaster. Conversely, functional genomics resources and databases in other insect lineages are scarce. To provide a new platform to study gene regulation in insects, we generated ATAC-seq (Assay for transposase-Accessible Chromatin) for the first time during the development of the mayfly Cloeon dipterum, which belongs to Paleoptera, the sister group to all other winged insects. With these comprehensive datasets along six developmental stages, we characterised pronounced changes in accessible chromatin between early and late embryogenesis. The application of ATAC-seq in mayflies provides a fundamental resource to understand the evolution of gene regulation in insects.

Biologists @ 100 - join us in Liverpool in March 2025
We are excited to invite you to a unique scientific conference, celebrating the 100-year anniversary of The Company of Biologists, and bringing together our different communities. The conference will incorporate the Spring Meetings of the BSCB and the BSDB, the JEB Symposium Sensory Perception in a Changing World and a DMM programme on antimicrobial resistance. Find out more and register your interest to join us in March 2025 in Liverpool, UK.
Pathway to Independence Programme: our 2024 PI fellows
Following a successful pilot year in 2023 with a fantastic set of postdocs (several of whom are now establishing their own labs), we are delighted to be working with our second cohort of Pathway to Independence (PI) fellows, who we will be supporting with training, mentoring and networking opportunities over the coming years.
Development presents…
Development is excited to host a webinar series showcasing the latest developmental biology and stem cell research. The webinars are chaired each month by a different Development Editor, who invites talks from authors of exciting new papers and preprints. Visit Development presents... on the Node to see which topics are coming up and to catch up on recordings of past webinars.
40 years of the homeobox
2024 marks the 40th year since the discovery of the homeobox in 1984, a landmark that fundamentally impacted several fields including genetics, developmental biology, neuroscience and evolution. To celebrate this anniversary, Development has commissioned a series of articles from leaders in the field demonstrating the impact of the homeobox discovery on different disciplines.
