Expression of a human cDNA in moss results in spliced mRNAs and fragmentary protein isoforms [article]

Oguz Top, Stella W.L. Milferstaedt, Nico van Gessel, Sebastian N.W. Hoernstein, Bugra Oezdemir, Eva L. Decker, Ralf Reski
2020 bioRxiv   pre-print
Production of biopharmaceuticals relies on the expression of mammalian cDNAs in host organisms. Here we show that the expression of a human cDNA in the moss Physcomitrella patens generates the expected full-length and four additional transcripts due to unexpected splicing. This mRNA splicing results in non-functional protein isoforms, cellular misallocation of the proteins and low product yields. We integrated these results together with the results of our analysis of all 32,926
more » ... P. patens genes and their 87,533 annotated transcripts in a web application, physCO, for automatized codon-optimization. A thus optimized cDNA results in about eleven times more protein, which correctly localizes to the ER. An analysis of codon preferences of different production hosts suggests that similar effects also occur in non-plant hosts. We anticipate that the use of our methodology will prevent so far undetected mRNA heterosplicing resulting in maximized functional protein amounts for basic biology and biotechnology.

Selfing in Haploid Plants and Efficacy of Selection: Codon Usage Bias in the Model Moss Physcomitrella patens

Péter Szövényi, Kristian K. Ullrich, Stefan A. Rensing, Daniel Lang, Nico van Gessel, Hans K. Stenøien, Elena Conti, Ralf Reski
2017 Genome Biology and Evolution  
A long-term reduction in effective population size will lead to major shift in genome evolution. In particular, when effective population size is small, genetic drift becomes dominant over natural selection. The onset of self-fertilization is one evolutionary event considerably reducing effective size of populations. Theory predicts that this reduction should be more dramatic in organisms capable for haploid than for diploid selfing. Although theoretically well-grounded, this assertion received
more » ... mixed experimental support. Here, we test this hypothesis by analyzing synonymous codon usage bias of genes in the model moss Physcomitrella patens frequently undergoing haploid selfing. In line with population genetic theory, we found that the effect of natural selection on synonymous codon usage bias is very weak. Our conclusion is supported by four independent lines of evidence: 1) Very weak or nonsignificant correlation between gene expression and codon usage bias, 2) no increased codon usage bias in more broadly expressed genes, 3) no evidence that codon usage bias would constrain synonymous and nonsynonymous divergence, and 4) predominant role of genetic drift on synonymous codon usage predicted by a model-based analysis. These findings show striking similarity to those observed in AT-rich genomes with weak selection for optimal codon usage and GC content overall. Our finding is in contrast to a previous study reporting adaptive codon usage bias in the moss P. patens.

Change your Perspective: Exploration of a 3D Network created from Open Data in an Immersive Virtual Reality Environment

Nico Reski, Aris Alissandrakis
unpublished
This paper investigates an approach of how to naturally interact and explore information (based on open data) within an immersive virtual reality environment (VRE) using a head-mounted display and vision-based motion controls. We present the results of a user interaction study that investigated the acceptance of the developed prototype, estimated the workload as well as examined the participants' behavior. Additional discussions with experts provided further feedback towards the prototype's

The results indicate that the participants were enthusiastic regarding the novelty and intuitiveness of exploring information in a VRE, as well as were challenged (in a positive manner) with the applied interface and interaction design. The presented concept and design were well received by the experts, who valued the idea and implementation and encouraged to be even bolder, making more use of the available 3D environment.
