Summary

The dachshund gene of Drosophila encodes a putative transcriptional regulator required for eye and leg development. We show here that dachshund is also required for normal brain development. The mushroom bodies of dachshund mutants exhibit a marked reduction in the number of (α) lobe axons, a disorganization of axons extending into horizontal lobes, and aberrant projections into brain areas normally unoccupied by mushroom body processes. The phenotypes become pronounced during pupariation, suggesting that dachshund function is required during this period. GAL4-mediated expression of dachshund in the mushroom bodies rescues the mushroom body phenotypes. Moreover, dachshund mutant mushroom body clones in an otherwise wild-type brain exhibit the phenotypes, indicating an autonomous role for dachshund. Although eyeless, like dachshund, is preferentially expressed in the mushroom body and is genetically upstream of dachshund for eye development, no interaction of these genes was detected for mushroom body development. Thus, dachshund functions in the developing mushroom body neurons to ensure their proper differentiation.

A new society for regenerative biologists

Kenneth Poss and Elly Tanaka announce the launch of the International Society for Regenerative Biology (ISRB), which will promote research and education in the field of regenerative biology.

Upcoming special issue: call for papers

The Immune System in Development and Regeneration
Guest editors: Florent Ginhoux and Paul Martin
Submission deadline: 1 September 2021
Publication: Spring 2022

The special issue welcomes Review articles as well as Research articles, and will be widely promoted online and at key global conferences.

An interview with Cagney Coomer

Over a virtual chat, we spoke to Cagney Coomer about her experiences in the lab, the classroom and the community centre, and why she thinks outreach and role models are vital to science.

Development presents...

Our successful webinar series continues into 2021, with early-career researchers presenting their papers and a chance to virtually network with the developmental biology community afterwards. Here, Michèle Romanos talks about her new preprint, which mixes experimentation in quail embryos and computational modelling to understand how heterogeneity in a tissue influences cell rate.

Save your spot at our next session:

10 March
Time: 9:00 (GMT)
Chaired by: Thomas Lecuit

Join our mailing list to receive news and updates on the series.
