A fully funded PhD position is open in the lab, to work on figuring out what are the photosynthetic "organelles" in the protist Meringosphaera. The overarching goals of this four-year PhD project are to identify the closest free-living relatives to the endosymbionts, and to characterize the levels of cellular, genetic, and metabolic integration of the endosymbionts to pinpoint the nature of this endosymbiosis. A suite of single cell methods will be employed, including single-cell genomics and metagenomics, and we have also planned for confocal scanning microscopy, transmission electron microscopy, and focused ion beam-secondary electron microscopy (FIB-SEM). This is a collaboration with the lab of Rachel Foster at Stockholm University.

The Editors’ Highlights pages aim to showcase the 50 best papers recently published in an area. The highlights can be accessed at www.nature.com/collections/jadchbbhdi.  We are delighted that the Swedish Research Council has granted us funding for four years to continue our work on characterising the endosymbiotic relationship in the marine protist Meringosphaera. This work started off with a scholarship from Carl Tryggers that supported Dr. Vasily Zlatogursky (see here for the paper), and is now being carried out by Megan Sorensen in collaboration with the lab of Dr. Rachel Foster at Stockholm University with a postdoc grant from SciLifeLab. With this new grant, we will be seeking soon a PhD student; stay tuned.  We recently welcomed two new members of the lab: Christina who is visiting us from Aalborg University to develop an environment specific database using long-read amplicon sequencing, and Thomas as a master student who will explore metagenomic datasets for plastid genomes.
But we are also getting ready to see Mahwash graduate with PhD, which will be a very special moment for us (first PhD student of the lab) but also sad because it means that she will soon leave. We are happy to announce the publication of two papers, now available at:
