CRISPR/Cas and related technologies in Drosophila cells and in vivo workshop


Stephanie Mohr, Harvard Medical School
Jonathan Zirin, Harvard Medical School
Justin Bosch, Harvard Medical School

CRISPR/Cas technologies are facilitating new and more precise studies in Drosophila. Through brief presentations, follow-up questions, and moderated discussion, we will engage the community in a conversation about new and emerging CRISPR/Cas and related technologies that facilitate small- and large-scale studies. The workshop will also increase awareness of relevant available fly stocks and other community resources. At the end of the online workshop, we will announce the time and place for an informal get-together for any attendees and presenters who will be on-site at the ADRC 2023 in Chicago.

The Ecdysone Workshop has a long and rich history at the Annual Drosophila Research Conference. Here we propose to continue this tradition by highlighting the diverse roles of insect hormones and small molecule metabolites in development, reproduction, metabolism, behavior, and disease. Most presentation slots will be reserved for trainees and new investigators.

The Neighborhoods Project: Leveraging cultural community connections to develop novel, collaborative genetics research projects

Alana O’Reilly, Fox Chase Cancer Center
Sarah Bay, Genetics Society of America

For many of us, a science career can be isolating, distancing us from the people we care about most. How would it feel to belong to a group of scientists who embrace our cultural connections and then join forces to build novel research projects founded on these deeply personal tenets?  In this workshop, “Neighborhoods” comprised of scientists committed to addressing genetics-related community challenges will be formed. Together, “neighbors” will 1) define a problem and 2) outline research plans to tackle the issue. We aim to foster a climate of friendship, mentoring, leadership, and discovery, built from a culturally-infused scientific foundation.

To participate in the Neighborhoods Workshop, please read the workshop information sheet as soon as possible and complete the Neighborhoods Worksheet by the end of February. password: #DROS21st0pSp@m

Developmental Mechanics

Rodrigo Fernandez-Gonzalez, University of Toronto
Guy Tanentzapf, University of British Columbia
Adam Martin, Massachusetts Institute of Technology

Developmental biology has undergone a revolution over the last two decades, largely as a result of work in Drosophila, that placed biomechanical, quantitative imaging, and mathematical modeling approaches at the forefront of the study of tissue morphogenesis. In particular, the establishment of tools to measure and manipulate mechanical forces in living organisms has demonstrated that mechanical forces profoundly shape animal development. In this workshop, we will review the most recent technical advances to visualize and quantify force generation in Drosophila, and we will discuss the latest results demonstrating the interplay between physical forces, molecular dynamics and tissue morphogenesis.

Non-traditional fly models: Contributions and research opportunities

Urs Schmidt-Ott, University of Chicago

The goals of the workshop are to foster the community of researchers that use non-traditional fly models as a natural laboratory for different purposes and to encourage young scientists to look beyond the wonderful Drosophila melanogaster model. The diversity of dipteran insects offers countless research opportunities to address questions that cannot be addressed in Drosophila melanogaster or that illuminate the phylogenetic roots of Drosophila melanogaster’s idiosyncrasies. The workshop will bring together researchers that explore this natural laboratory at the neural, behavioral, molecular, cellular, genetic, or genomic levels.

Immunometabolism: Flying 10 Years later

Francesca Di Cara, Delahousie
Jason S Karpac, Texas A&M University School of Medicine
Neal Silverman, UMass Chan Medical School

It took over 100 years before immunologists realized that metabolic pathways are not only “energy suppliers” but regulators of immune and inflammatory signaling.  Immune cells play major roles in metabolic homeostasis and the impact of metabolic pathways on immune cell function. Discoveries from studies in Drosophila helped to reveal the tangled links between immunology and metabolism. This workshop will cover works demonstrating how metabolic shifts within immune cells and extracellular effects on key target tissues are integrated to affect whole-body physiology. It will also focus on emerging technologies to study such systems in Drosophila.

9:00 p.m. Jason S Karpac, Texas A&M University, “Exploring the complex integration of life history and immunometabolic responses”.
9:15 p.m. Group Discussion

Evolutionary and Population -omics at the Scale of Model Clade Drosophilidae


Dmitri Petrov, Stanford University

Bernard Kim, Stanford University

Short summary:

The Family Drosophilidae is a premier model system for biology and genomics, and continued rapid technological improvements allow for these organisms to be studied with genomics at increasingly precise resolution. A foundational part of developing the entire >4,500 species family into a system for clade-scale genomics is cheap yet high quality genome assemblies, which we are now able to perform from single flies at a cost of <100 US dollars per genome. This makes it feasible to scale our efforts towards sequencing every species in this important group. As a next step, we aim to sequence the genomes of at least 1,000 drosophilid species but also to generate population sequencing data for 200 species by 2024, and ultimately the whole of Family Drosophilidae. Importantly, these data are generated in collaboration with many in the fly community and with the intent of building an open resource. Through a series of talks, this workshop will provide attendees with background on sampling and sequencing methods, bioinformatic tools, data access, and phylogenomic methods. Next, efforts utilizing these data to understand transposable elements, the evolution of phenotypes, and drosophilid-associated microbes at the scale of the entire family will be presented. Finally, the workshop will feature an interactive Q&A and discussion at the end to solicit feedback from attendees, and to provide ways to participate and contribute to this large collaborative effort.
