Summary

The PAR-1 kinase is required for the posterior localisation of the germline determinants in C. elegans and Drosophila, and localises to the posterior of the zygote and the oocyte in each case. We show that Drosophila PAR-1 is also required much earlier in oogenesis for the selection of one cell in a germline cyst to become the oocyte. Although the initial steps in oocyte determination are delayed, three markers for oocyte identity, the synaptonemal complex, the centrosomes and Orb protein, still become restricted to one cell in mutant clones. However, the centrosomes and Orb protein fail to translocate from the anterior to the posterior cortex of the presumptive oocyte in region 3 of the germarium, and the cell exits meiosis and becomes a nurse cell. Furthermore, markers for the minus ends of the microtubules also fail to move from the anterior to the posterior of the oocyte in mutant clones. Thus, PAR-1 is required for the maintenance of oocyte identity, and plays a role in microtubule-dependent localisation within the oocyte at two stages of oogenesis. Finally, we show that PAR-1 localises on the fusome, and provides a link between the asymmetry of the fusome and the selection of the oocyte.

An interview with Swathi Arur

Swathi Arur joined the team at Development as an Academic Editor in 2020. Her lab uses multidisciplinary approaches to understand female germline development and fertility. We met with her over Zoom to hear more about her life, her career and her love for C. elegans.


Jim Wells and Hanna Mikkola join our team of Editors

We are pleased to welcome James (Jim) Wells and Hanna Mikkola to our team of Editors. Jim joins us a new Academic Editor, taking over from Gordan Keller, and Hanna joins our team of Associate Editors. Find out more about their research interests and areas of expertise.


New funding scheme supports sustainable events

As part of our Sustainable Conferencing Initiative, we are pleased to announce funding for organisers that seek to reduce the environmental footprint of their event. The next deadline to apply for a Scientific Meeting grant is 26 March 2021.


Read & Publish participation continues to grow

“I’d heard of Read & Publish deals and knew that many universities, including mine, had signed up to them but I had not previously understood the benefits that these deals bring to authors who work at those universities.”

Professor Sally Lowell (University of Edinburgh) shares her experience of publishing Open Access as part of our growing Read & Publish initiative. We now have over 150 institutions in 15 countries and four library consortia taking part – find out more and view our full list of participating institutions.

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
