12.5.21: Prof. Dr. Debashish Bhattacharya. Department of Biochemistry and Microbiology, Rutgers University, U.S.A.

Title: The rare emergence of a photosynthetic organelle.

bhattacharya Abstract

Endosymbiosis, when stable and beneficial for the “host” cell, can result in massive genetic innovation with the foremost examples being the mitochondrion and plastids. I will present results of our analysis of the rhizarian amoeba Paulinella that comprises an independent case of primary plastid endosymbiosis that occurred ca. 120 Mya. Genomic and physiological data will be used to highlight the many innovations that are needed to maintain a permanent photosynthetic endosymbiont.

19.5.21: Dr. Agostina Sassone. Leibniz Institute of Plant Genetics and Crop Plant Research. 

Title: Tackling the taxonomy of Nothoscordum (Amaryllidaceae, Allioideae). 

nothoscordum1

Abstract

Nothoscordum Kunth is a plant genus closely related to onions and garlic but occurs, in contrast to them, nearly exclusively in South America. It is currently not clear how Nothoscordum species are related to each other, how and where they evolved and are distributed today, and not even how many species belong to this genus. The main aim of my research is to generate an integrative approach considering morphological, karyological and molecular characters to answer these questions.

26.05.21: Double Seminar (30 minutes each)

Dr. Christian Siadjeu. Carl von Ossietzky Universität Oldenburg.

Title: Molecular breeding bases of trifoliate yam (Dioscorea dumetorum (Kunth) Pax) against post-harvest hardening phenomenon of tubers.

siadjeu1

Abstract

Yams (Dioscorea spp.) are important and economical food for millions of people in the tropics and subtropics. Dioscorea dumetorum has the highest nutritional value compared to the other cultivated yam species with important medicinal properties. Despite these advantages, its cultivation is jeopardized by the post-harvest hardening (PHH) phenomenon characterized by the inability of tubers to soften during cooking. The PHH begins within 24 h after harvest and causes tubers to become inedible. Although several techniques have been deployed to solve this issue, they failed to overcome the PHH. The main objective of this thesis was to provide the basis of genetic breeding for avoidance of the PHH in D. dumetorum.

Title: Genes documenting history: Biogeographical dynamics of selected Brassicaceae taxa and climate-landscape history of the Eurasian steppe belt.

anzepic1

Abstract

The Eurasian steppe belt is the vastest grassland region worldwide that has been under immense influence of the Neogene climate events. Despite its size, however, the onset and evolution of its flora is poorly understood. By employing a plethora of different phylogenetic, phylogeographic and biogeographic methods, I placed the evolutionary history of four Eurasian steppe floral elements into time and space. Interestingly, while nowadays considered an integral part of steppe flora, most of the investigated taxa migrated into the Eurasian steppe belt long after it was already developed. Several migration routes of different ages as well as different Pleistocene refugia point towards a very complex evolutionary history of the steppe flora, a glimpse of which I will give you in my talk.
