Dessi will now work 100% at the DEE. She will still be working at 40% for the Pannell group but will work 60% for the DEE. She will continue to coordinate and organize the 4th floor common lab and will support Anne-Lyse with the organization of the big 2nd floor lab and take-over some technical lab tasks and equipment to support the Lab Team. We are very pleased to have Dessi with us full time.

Prof. Cleo Bertelsmeier participated in a segment of the Micro Sciences podcast on the programme "CQFD" (RTS). Entitled "Why are there ants in my flat?", Cleo explains how and why ants invade city dwellings. Aired on Friday, 25.06.2021. Listen

Congratulations to Dr. Giulia Zancolli and Prof. Erica Van de Waal on obtaining a Pro-Femmes grant from the FBM!
|
Giulia obtained the grant for her project "Regulatory evolution of animal venom system" and it will allow her to establish spatial transcriptomics of cone snail venom glands, and will support her application to SNF funding for venom Evo-Devo.
|
|
Erica obtained the grant for her project "From the individual to the system: Understanding knowledge movement". The funding will allow her to employ a scientific manager at her field site in South Africa, as well as a data manager here at UNIL to work on the long-term (11 years) database of the project.

Congratulations to Prof. Robert Waterhouse who was awarded a grant for the extension of his SNSF assistant Professor fellowship to develop computational analysis methods for studying genomic innovations underlying arthropod success and diversity.

Using whole genome alignments across multiple mosquito species, highly variable loci flanked by highly conserved regions were identified and used to build a multilocus amplicon panel for very large-scale mosquito genetic surveillance and vector control. Prof. Robert Waterhouse, in collaboration with colleagues from the Wellcome Sanger Institute, developed these tools and protocols which are now published in Molecular Ecology Resources. The panel also contains loci from the Plasmodium mitochondrion, allowing for simultaneous identification of both the mosquito species and whether that mosquito carries malaria parasites!

By fertilising plants with more P the benefit of mycorrhizal fungi on plant growth also decreases. We call this the P inhibition paradigm because it has been clearly demonstrated in hundreds of greenhouse experiments. Because of this, agronomists assume that it's only useful to use mycorrhizal fungi when crops are not fertilised. In cassava cropping in Tanzania and Kenya we showed that the the paradigm does not hold true in field conditions and that responsiveness to inoculation can happen even when plants are given lots of P fertiliser. (Prof. Ian Sanders, in collaboration with IIITA, Kenya/Cameroon; NARI, Tanzania and National University of Colombia). Published in Frontiers.

Current members of the Sanders group (Ivan Mateus and Soon-Jae Lee) published a response in ISME Journal to a strong critique of the results of their previous publication. In this reply, they demonstrated that the re-analysis of their data, and the subsequent conclusions, contained in the critique were completely invalidated by fundamental bioinformatic errors. In the reply, Mateus and co-authors, confirm that upregulation of genes involved in a putative mating response have indeed been observed between mycorrhizal fungal genotypes specifically when co-exisiting in plant roots.

Arbuscular mycorrhizal fungi, which fossil records are dated back to 400 mya, have been called long lived asexual scandals because no sexual structures have ever been identified. Previous reports have shown: 1) AMF contain a complete meiosis machinery, 2) a putative MAT-locus and 3) the upregulation of genes related to mating when two isolates co-exist. In this bioRxiv preprint, members from Sanders group (Ivan Mateus, Joaquim Cruz, Soon-Jae Lee) and the First Step student Malick Ndiaye shown that AMF dikaryon genomes display signatures of reciprocal recombination between nuclei containing different putative MAT-types. These results suggest that AMF displays a sexual reproduction life style.
