Meet the lab of Chema Martín-Durán @Chema_MD, based at Queen Mary University of London, UK.

The lab studies segmented worms with spiral cleavage to understand how development is controlled and evolves to generate new phenotypes #EvoDevo

For our #MidweekMovie, we are recommending that you catch up with the #DevPres talks on @the_node. The speakers, Hannah Gruner, Seth Donoughe & @allan_littlecar all use microscopy to address research questions in #evodevo.

Genomic Analysis of a Scale Worm Provides Insights into Its Adaptation to Deep-Sea Hydrothermal Vents https://doi.org/10.1093/gbe/evad125 #science #evolution #biology #genome #evolgen_paper

We published a new preprint on nitric oxide (NO) signalling in #Platynereis. In the paper Kei Jokura et al. described how NO is required for UV-avoidance behaviour by mediating retrograde signalling to brain ciliary photoreceptors.

🚨The Martín-Durán Lab is recruiting a PostDoc and a PhD to investigate how larvae evolved! Supported by Leverhulme Trust at Queen Mary University of London, join a terrific group of people to investigate fascinating marine 🪱🪱!

DM/e-mail (chema.martin@qmul.ac.uk) for more info!

In our new preprint we characterise neuropeptide signalling in the cnidarian #Nematostella.
https://www.biorxiv.org/content/10.1101/2023.07.03.547448v1
Daniel Thiel and Luis Yanez-Guerra screened 64 neuropeptides against 161 G-protein coupled receptors (#GPCR) and found activating peptide ligands for 31 receptors.

Last, but by no means least, at #GRCdevbio23 is @Honghao_Song from @redmakeda's lab at @Harvard

Together, the Extavour lab investigates the evolution of the reproductive system.

@redmakeda is also a @Dev_journal Editor and Chair of our next #DevPres webinar on 2 August.

Take a look at the #DevPres programme of speakers on @the_node

@albertcardona Nice work. I reached a similar conclusion when looking at engrailed expression across metazoans. From https://doi.org/10.1038/srep32387

But I don't think the conserved genetic boundary suggests the homology of brains. To me, it supports the homology of a head-trunk distinction in early development.

The brain of protostomes and deuterostomes could well have evolved independently using this common genetic basis.

Spatial transcriptomics sheds light on the #echinoderm body plan!

#preLight from Rodrigo Senovilla-Ganzo.

Rodrigo covers a #preprint from #lab_lowe showing that the bilaterian antero-lateral axis shifts to medio-lateral in the #ectoderm of adult echinoderms.

My first contribution/collaboration in the lab of Jordi Solana is out!

First cell type atlas of the annelid Pristina leidyi uncovering a bunch old and new cell types, generating networks of gene coexpression, and identifying piwi-positive cells as pluripotent lineage giving rise of all cell types.

It was so fun to develop and learn graph methods for this work. Congrats to all the authors!

Thrilled to see our latest work highlighted on the cover of Science 🤩. Our discoveries challenge our understanding of nervous systems and their evolution. Link to the paper here:

In a month I'll be heading to my alma mater University of Costa Rica to present some of our work on axial specification in annelids 🪱

En un mes estaré presentando nuestro trabajo en especificación de ejes en anélidos en mi alma mater Universidad de Costa Rica

#EvoDevo #WormWednesday #CienciaCriolla

We are really excited to share the news that for the first time, EuroEvoDevo will have five satellite meetings @EED2024 Helsinki! Endless #EvoDevo most beautiful!
Save the dates:
📅June 24 & 25, 2024: Satellites
📅June 25 – 28, 2024: Main EED Meeting

Thanks to the organizers! More info soon on http://www.euroevodevo2024.fi

@Chema_MD presenting our work at the Gene Regulatory Networks meeting #EvoDevo #GRN2023

Thanks to Bernard and Sandie Degnan for including our annelid life cycle paper in their spotlight for Trends in Genetics

"How larvae and life cycles evolve"

Good that our work keeps on making a contribution to the community

I'm excited to announce that our cephalic furrow paper is out! We investigated the function of this enigmatic invagination using live imaging and modeling and found that it plays a mechanical role during fly gastrulation https://www.biorxiv.org/content/10.1101/2023.03.30.534554

Featuring awesome contributions form a load of great researchers.

#FluorescentFriday

Some antibodies arrived a few weeks ago, so we tested in Capitella. Looking forward to testing them in Owenia 🪱

Very excited to see the launch of the 1st cohort of @Dev_journal Pathway to Independence (PI) Fellows

8 postdocs we'll follow & support as they navigate the academic job market

You'll be hearing more from them & about the PI programme in the near future

This #WormWednesday we welcomed a box full of possibilities 💪🏼

Owenia is back 🪱!!!, plus some extra spiralian friends 🐌

Thanks to the Roscoff Marine Station for the package 🏴󠁧󠁢󠁥󠁮󠁧󠁿🤝🏼🇫🇷
