Kelsey Byers: The chemical ecology of plant-pollinator interactions

Alisandra Denton: Annotating Eukaryotic genomes with Deep Learning

Special Seminar
Gene calling, or structural gene annotation, is critical to extracting biological knowledge from a genome, yet existing methods for gene calling in Eukaryotes lag far behind genome sequencing and assembly in quality, ease and speed. However, we have every reason to believe gene calling is a tractable problem. The information about what is or is not a gene is encoded in the raw DNA sequence. Hence, we need to update our modeling. Deep Learning is a new and transformative technology that can model extraordinarily complex and non-linear relationships—like those found in biology—and has the potential to ‘decode’ the information in DNA. We have previously demonstrated the applicability of Deep Learning to gene calling in our project Helixer, which showed ground-breaking performance in classifying genic categories. Here we establish usability by post-processing the base-wise predictions from Helixer into full primary gene models with a Hidden Markov Model. Preliminary results in selected plant species indicate the resulting gene models redefine state-of-the-art for a de novo gene caller and—on some species—even approach reference quality as compared to RNAseq data. In the future, we will expand applicability across Eukaryotes and expand our annotation targets to include additional genomic features such as promotors. The improved annotations will support research methods from cloning to ‘omics analyses and a wide variety of applications including biomedical research and crop bioengineering. The code is available at https://github.com/weberlab-hhu/Helixer [mehr]

Alison Smith: Algal-bacterial interactions: how do mutualisms arise?

B-vitamins are organic micronutrients that play a vital role in cellular metabolism by providing enzyme cofactors. Most animals have lost the ability to synthesise these cofactors and obtain them in their diet, whereas plants can produce all their own compounds, and indeed are the major source of them for human nutrition. The situation is more complex for microbes with both producers and requirers are found in different species. Intriguingly this is also the case for microalgae, which despite their photosynthetic lifestyle are often auxotrophic for one or more B-vitamin. In particular more than 50% of microalgal species require vitamin B12 (cobalamin), the cofactor for methionine synthase, the central enzyme of C1 metabolism, essential for both DNA synthesis and production of S-adenosyl-methionine (SAM) the universal methyl donor, which in turn is required for methylation marks in DNA and histones. Here I will describe our work on elucidating the molecular basis for B12-auxotrophy in microalgae, how this impacts metabolism and gene expression, and the possible role of vitamin exchange in initiating and maintaining microbial communities.

Amanda Souza Camara: Modeling the dynamics of plant chromosomes

Beyond the genomic sequence, the peculiar three-dimensional structure of the DNA largely varies during the cell cycle and even between tissues or species. Its different conformations and organization inside the nucleus are now recognized to affect epigenetic regulation. It is becoming increasingly important to understand the mechanisms that drive the spatial organization of the genome. In this seminar, I will consider the DNAs physical properties to model the compaction of chromocenters and holocentric chromosomes.” [mehr]

Herbivory is a common feeding strategy among mammals; yet, at every meal, herbivores are faced with the prospect of being poisoned by toxins naturally occurring in their diet. To understand differences in the detoxification abilities that exist among populations of the same species adapted to different diets, we use biochemical, pharmacological and genomic tools to identify and characterise critical liver enzymes. In addition to liver detoxification, we have experimentally documented that gut microbes play a key role in facilitating the ingestion of dietary toxins, and that these microbes and their function can be transferred to other populations and even other species of rodents. A holistic understanding of the mechanisms used by mammalian herbivores to process dietary toxins is essential for predicting and conserving biodiversity especially under changing climatic conditions.

Martin Mascher: Pan-genomics for crop improvement

Pan-genomic studies aim at representing the entire sequence diversity within a species to provide useful resources for evolutionary studies, functional genomics and breeding of cultivated plants. Cost reductions in high-throughput sequencing and advances in sequence assembly algorithms have made it possible to create multiple reference genome sequences along with a catalogue of all forms of genetic variations in plant species with large and complex or polyploid genomes. In this talk, we will summarize our work in barley pan-genomics: the selection of representative core sets by genebank genomics, the assembly of chromosome-scale reference sequences, and the discovery of structural variants associated with agronomic traits. A future challenge will be the development of pan-genome interfaces for easy access by breeders and geneticists. [mehr]
