Jane A. Langdale
Department of Plant Sciences, University of Oxford, UK

Title: Genetic regulation of leaf development in C₄ grasses

Host: Maria Eriksson

Room: Carl Kempe salen KB.E3.03


Abstract of her talk:
All grasses exhibit a characteristic strap shaped leaf blade but this consistent external morphology masks an underlying anatomical difference that distinguishes species that carry out C₄ versus C₃ photosynthesis. A multi-national effort aimed at introducing components of C₄ photosynthesis into the C₃ plant rice requires an understanding of the genetic regulation of C₄ leaf development, so that leaf anatomy can be manipulated in rice. I will provide an overview of our current understanding of C₄ leaf development, discuss recent research aimed at identifying genetic regulators of leaf anatomy, and illustrate how this research fits into the wider ‘C₄ Rice Project’.

Paul Hudson
Systems Biology, KTH, Stockholm, Sweden

Title: Synthetic and systems biology of cyanobacteria empowered with the CRISPRi tool

Host: Åsa Strand


More information about Paul Hudson's research: https://www.kth.se/profile/huds


Abstract for the talk:
Our group is using the inducible gene-repression tool CRISPRi in Synechocystis for multiple projects in metabolic engineering and systems biology. We have exploited the multiplex capability (6 sgRNAs) of CRISPRi to rapidly screen the effect of eliminating competing pathways on fatty alcohol production. In this case, we observed regulatory “compensation” when repressing genes around the acyl-ACP node. An inducible CRISPRi allows controlled repression of essential genes, and we have used repression of citrate synthase to arrest growth and direct flux to lactate, where specific productivities are increased several fold. I will discuss how sgRNA libraries, combined with droplet-based cell sorting for lactate secretion, can be used to find better strategies for arresting growth while keeping CO2 fixation high. Finally, I will give an example of how we use CRISPRi repression of enzymes to force accumulation of a metabolite, and perform subsequent transcriptomics to uncover metabolite-responsive gene regulation.

UPSC Seminar

Alain Goossens
VIB-UGent Center for Plant Systems Biology, Gent, Belgium

Title: A story on bHLH transcription factors in the regulation of plant terpene pathways

Host: Catherine Bellini


More information about Alain Goossens research: https://www.psb.ugent.be/specialized-metabolism


Abstract for the talk:
Across the plant kingdom, hormones such as the jasmonates steer the delicate balance between growth and the activation of defense programs, including the production of bioactive specialized metabolites. Plant cells are capable of producing an overwhelming variety of such specialized metabolites, both in terms of complexity and quantity. These molecules allow plants to cope with various types of stresses and often also have biological activities of high interest to human. Yet, this impressive metabolic machinery is still limitedly exploited, mainly because of the limited molecular insight into plant (specialized) metabolism. All of this is particularly applicable to the important class of plant terpenes as well. By using cutting-edge functional genomics tools in combination with reverse genetics screenings, we try to unravel the molecular mechanisms driving plant natural product biosynthesis in crop, medicinal and model plants, with a particular focus on terpenes.
Transcription factors of diverse families play essential roles in the signaling cascades triggered by the perception of jasmonates. Likewise, jasmonate-modulated transcription factors may act alone or in a combinatorial fashion with others, allowing interplay with other development or defense related processes. The transcription factors of the basic helix-loop-helix (bHLH) family play an essential and often conserved role in jasmonate signaling in the plant kingdom in general, and leading to the onset of terpene biosynthesis in particular. I will discuss on the identity, role and mode of action of bHLH factors in the conserved jasmonate-mediated elicitation of terpene metabolism of a number of model, medicinal and crop species, including Arabidopsis thaliana, Medicago truncatula and Catharanthus roseus.

UPSC Seminar

Tom Beeckman
Department of Plant Biotechnology and Bioinformatics, Ghent University and VIB-UGent Center for Plant Systems Biology, Gent, Belgium

Title: Root branching: cell and tissue communication shape the plant root system

Host: Catherine Bellini


More information about Tom Beeckman's research: https://www.psb.ugent.be/root-development

Abstract of his talk:
Root architecture is a trait that strongly contributes to the performance of plants. The way plant root systems colonize the soil will be determinative for the all or not thriving growth of the above ground parts. Because plants are sessile organisms, the exploration of soil in search of water and nutrients is mainly dependent on steering and controlling cell division and elongation.
The presence of an endogenous tissue layer in which, on a regular basis, stem cells with high cell division competence are deposited represents a powerful instrument through which plants can easily generate new lateral root branches. These branches are not arbitrarily formed along a root axis, but their spacing is rather determined by an endogenous patterning mechanism. Furthermore, it only rarely happens that lateral roots are formed close to each other. Both, the endogenous patterning mechanism combined with lateral inhibition signals guarantee an even distribution of lateral organs over the entire length of the root. New insights in these patterning mechanisms will be discussed with the emphasis on putative cellular and tissue communication systems that are involved.
