Parasites can alter behaviour of their hosts’ social environment

2018-06-21 Sticklebacks

Many parasites have evolved strategies to manipulate the behaviour of their host, e.g., risk-taking behaviour, to facilitate transmission to the next host. MGSE PhD student Nicolle Demandt was now involved in a study, which revealed that behavioural manipulation by parasites does not only affect the infected host, but also uninfected group members. Nicolle and her colleagues tested how three-spined sticklebacks, behaviourally altered by infections with the tapeworm Schistocephalus solidus, influenced the escape and risk-taking behaviour of uninfected group members after a simulated bird attack. Interestingly, uninfected individuals adjusted their risk-taking behaviour to the number of infected group members, taking more risk with an increasing number of infected group members. This result sheds new light on the social dynamics involved in host–parasite interactions. The results have been published in Proceedings of the Royal Society B: Demandt N, Saus B, Kurvers RHJM, Krause J, Kurtz J & Scharsack JP (2018) Parasite-infected sticklebacks increase the risk-taking behaviour of uninfected group members. Proceedings of the Royal Society B: Biological Sciences 285 10.1098/rspb.2018.0956.  The press release of the WWU can be found here. One of Nicolle’s supervisors, Dr. Jörn Scharsack, was also interviewed by the Deutschlandfunk about the findings of the study.

MGSE PIs demonstrate significant impact of transcriptional interference on gene expression

Proximal promoter regions in eukaryotes are heavily transcribed yielding different types of small RNAs. Their actual function has not been completely understood and it could not be ruled out that many of them are mere by-products of gene expression. MGSE PIs Prof. Dr. Wojciech Makalowski and Prof. Dr. Jürgen Brosius now investigated capped and polyadenylated small RNA transcripts within proximal promoter regions of human RefSeq genes and demonstrated that they regulate downstream gene expression via transcriptional interference. The small transcripts act via the occlusion of otherwise productive transcription factor/DNA interactions. The results have been published in Nucleic Acids Research: Pande A et al. (2018) Transcriptional interference by small transcripts in proximal promoter regions. Nucleic Acids Research 46: 1069-1088. Press release of the WWU

The 7th MGSE Symposium was held on 21 – 22 March 2018 at the Institute for Evolution and Biodiversity at the University of Münster. Around 60 participants attended the two-day event which again offered the graduate students the opportunity to present their research in an oral presentation or a poster. For the first time, also PhD students from the Research Training Group EvoPAD – who are associated to the MGSE – were invited to share their first results, to network with evolutionary biologists in and around Münster, and to gain presenting experience. The programme was completed by talks of four MGSE Principal Investigators and three excellent keynote speakers: On the first day, Michael Lynch – member of the National Academy of Sciences and famous for his work supporting neutral theories of evolution – focussed on evolution at the molecular level. On the second day, Leo Beukeboom and Paula Stockley gave insights into the evolution of sex determination systems and post-copulatory sexual selection.
We would like to thank all presenters and guests who helped making the MGSE symposium a great event again, showing off the diverse research within the graduate school. Programme and pictures...

ETT-Fellow Prof. Dr. Chris Smith has now published a study which was supported by the Evolution Think Tank of the MGSE. In their work, Prof. Smith and his co-authors identify a highly conserved expression pattern in an insect-only gene family, the Osiris genes, that is essential for development, but also plays a significant role in phenotypic plasticity and in immunity/ toxicity responses. Chris Smith has been a Fellow of the Evolution Think Tank from May to June 2017. The publication can be found here: Smith CR, Morandin C, Noureddine M & Pant S (2018) Conserved roles of osiris genes in insect development, polymorphism and protection.

Eyebrow First Issue
© WWU/MGSE

The MGSE PhD students proudly present the very first issue of The Eyebrow – a magazine for and by PhD students of the MGSE. “It is a magazine written, edited, formatted, and ultimately yielded by PhD students of the Münster Graduate School of Evolution. We do not aim to inform, yet we will. We aim not to elucidate, but we will. We do, however, aim to entertain, by letting thoughts run freely,” describes Editor-in-Chief April Snøfrid Kleppe the vision of the magazine in the issue’s editorial. The magazine features reportages from different MGSE groups, news of future and passed events, essays as well as cartoons and riddles, providing beautiful distraction for long days in the lab. The Eyebrow is currently the only student paper at the WWU and is planned to be published quarterly. The fact that the first issue turned out as well as it is shows the potential of the upcoming issues. To convince yourself, you can pick up your copy of The Eyebrow in the MGSE office building in Hüfferstr. 1a. A PDF version of The Eyebrow in colour can be downloaded from the website of the magazine: https://eyebrowevolution.wordpress.com/

Insights into molecular basis of termite eusociality

9359-qp6jpijo
© WWU/Peter Leßmann

Termites evolved eusociality - the reproductive division of labour with overlapping generations and cooperative brood care - independently from and long before social Hymenoptera. A team of researchers led by MGSE PI Prof. Dr. Erich Bornberg-Bauer could now show evolutionary signatures of termite eusociality by comparing the genomes and transcriptomes of three termites and the German cockroach against the background of 16 other eusocial and non-eusocial insects. Their result provide further evidence that major changes in gene regulation and the evolution of sophisticated chemical communication are fundamental to the transition to eusociality in insects. Although this parallels molecular mechanisms of eusocial evolution in Hymenoptera, the specific solutions are remarkably different, thus revealing a striking case of convergent evolution.
