'' Auxin signaling: more than we could ever imagine '' Prof Jiri Friml Institute of Science and Technology Austria (ISTA) Klosterneuburg AUSTRIA Friday, October 14, 2022 14:00 The plant hormone auxin is a versatile intercellular signal influencing virtually all aspects of plant life. It has a unique ability to be directionally transported within tissues forming local auxin maxima or gradients that are central to many developmental processes mediated by auxin. One of the key roles of auxin is adaptation of plant growth to gravity, where shoots bend up and roots down. This paradox is based on opposite responses of these organs to the phytohormone auxin, which promotes cell expansion in shoots, while inhibiting it in roots via an unclear signalling pathway and yet unknown downstream cellular mechanism. The well-established canonical auxin signalling involving the TIR1/AFB auxin receptors, Aux/IAA repressors and ARF transcription factors acts in nucleus and mediates gene transcription. However, auxin also triggers cellular responses within seconds or minutes, too fast to rely on transcription. Part of the rapid responses is mediated by the non-transcriptional branch of the TIR1/AFB signalling, but others involve a yet completely unknown mechanism. Here Prof Jiri Friml will present new and surprising insights into the mechanism of auxin signalling including an ultrafast auxin-triggered protein phosphorylation response and previously unsuspected aspects of TIR1/AFB auxin perception and downstream signalling. Keywords : Auxin, Arabidopsis, root gravitropism, TIR1/AFB signalling Acknowledgements : Prof Jiri Friml gratefully acknowledges all present and past members of the Friml group and their excellent collaborators.

'' Connecting the dots: how dynamic regulations output cellular functions '' Dr Lisa Van den Broeck Plant and Microbial Biology Department North Carolina State University Raleigh USA Thursday, October 20, 2022 11:00 Plants are challenged by a constantly changing environment. In response to these environmental signals as well as developmental cues, plants will meticulously adjust and finetune their growth. To manipulate plant growth, it is thus key to understand the regulations that integrate these signals and elicit a timely and coordinated response. Through probabilistic and machine learning inference methods, we have identified central regulators during development in Arabidopsis, tomato, pepper, and soybean. However, studying dynamic regulations in non-model species appeared challenging as a result of poor functional annotation of regulatory proteins. To overcome such limitations, we leveraged the advantages of artificial intelligence to predict protein function or sequence domains, including transcriptional activation domains. Finally, to further dissect the cellular signals in changing environments, we have established a framework for 3D bioprinting plant cells to study cell viability, cell division, and cell identity. The framework established here paves the way for a general use of 3D bioprinting for studying cellular responses in a tunable environment.

'' Gene regulatory dynamics of germinating seeds from bulk tissue to single-cell resolution '' Associate Prof Mathew Lewsey La Trobe Institute for Sustainable Agriculture and Food La Trobe University Bundoora AUSTRALIA Tuesday, October 25, 2022 11:00 “Seeds provide 70% of global food resources, being the most valuable output from plant production. They also play a critical role in agriculture because the lifecycle of most crops begins from seed germination. Uniform germination enables growers to achieve optimal plant-spacing and harvesting time. Despite this importance, we do not have a complete understanding of how seed germination is regulated, which limits our ability to improve its properties. We have made much progress identifying regulators by traditional bulk-tissue 'omics approaches. Through these we have discovered transcription factors that control both gene expression and the progress of germination. However, the seed is a complex structure comprised of many tissues and cell-types, each of which have distinct properties. Changes in gene expression occur in these cell-types throughout germination and are expected to be context-dependent, to enable spatiotemporal control of cellular processes. To better understand how gene expression is controlled within individual seed cell-types we have carried out single-cell RNA-Seq in germinating Arabidopsis embryos. We analysed seeds at three time points after stratification: 12 hours (mucilage excretion), 24 hours (testa rupture) and 48 hours (radicle emergence). We then identified individual cell-types within the embryo, annotated their identities and studied how they changed over time. This study provides unprecedented insight into the transcriptome of the germinating Arabidopsis embryo and genome regulatory network during seed germination. It will help us to develop practical solutions to promote the seed-to-seedling transition and to ensure germination happens uniformly at the right time.” Jozef Schell seminar room Technologiepark 71 - 9052 Invited by Prof Dirk Inzé and Prof Klaas Vandepoele If you do not wish to receive this information anymore, please unsubscribe from future mailings at [ https://maillist.psb.ugent.be/mailman/listinfo/seminars | https://maillist.psb.ugent.be/mailman/listinfo/seminars ] Genome editing, cutting-edge technology for a sustainable agriculture VIB-UGent Center for Plant Systems Biology Ghent University Technologiepark-Zwijnaarde 71 9052 Ghent-Belgium Phone: +32(0)9 331 38 00 [ http://www.psb.vib-ugent.be/ | https://www.psb.ugent.be/ ]

'' The endodermal passage cell - novel functions hidden in plain sight? '' Dr Tonni Grube Andersen Max Planck Institute for Plant Breeding Research, MPIPZ GERMANY Thursday, November 24, 2022 11:00 Anatomically, roots consist of the central vascular cylinder enclosed by the endodermal, cortex and epidermal cell layers. The innermost endodermis contains apoplasmic barriers - Casparian Strips (CS) - that allow selective solute uptake from the soil by forcing transport across the plasma membrane. In older root parts, the entire surface of most endodermal cells is covered by suberin lamellae, which block transport across the plasma membrane and thereby likely renders the endodermal cell insensitive to its surroundings. However, some few cells situated at the endodermal xylem poles remain unsuberized. As they may form a path of low resistance for radial flow of solutes through an otherwise sealed endodermis, these cells have been termed “passage cells” (PCs) despite lack of functional evidence. Intriguingly, suberization and passage cell occurrence is highly dynamic and responsive to nutritional stress, which suggests an active role in nutrient homeostasis. While the effect of several nutrients has been investigated, very little is known of how the N-status affects this intriguing dynamic barrier system. Surprisingly, we found that nitrogen starvation results in an oversuberization of the endodermis and consequent closure of PCs. . To get mechanistic insight into this, we employed tissue-specific Translating Ribosome Affinity Purification (TRAP) which allowed us to gain new insights into how old root parts respond to chronic N-starvation a tissue-specific manner. We use fluorescent, transcriptional reporter lines and vertical microscopy to investigate long-term responses of candidate genes upon varying mineral nitrogen availability. Our findings reveal exciting new insights into the role of this intriguing cell type. As tissue-specific roles in nitrogen use efficiency (NUE) have a huge agricultural impact, these finding may allow us to expand on our current models for NUE to include older root parts and their role in (a)biotic communication.

'' Mapping the Cysteine Redoxome '' Prof Jing Yang National Center for Protein Sciences CHINA Tuesday, November 29, 2022 11:00 The nucleophilic thiol group (Cys-SH) allows cysteine to undergo a broad range of redox modifications, such as sulfenylation (Cys-SOH), sulfinylation (Cys-SO2H). Emerging evidence suggests that cysteine redox modifications are well-controlled, site-specific cellular events, which play important roles in regulating many biological processes, such as autophagy, cellular metabolism, inflammation, cell cycle and cell death under physiological and pathological contexts. Efforts to understand their underlying mechanisms have been hampered due to limitations of methods for globally analyzing site-specific protein targets and redox dynamics. We have recently developed several chemoproteomic approaches to globally map and to quantify Cys-SH, Cys-SOH and Cys-SO2H in complex proteomes, providing versatile opportunities to study cysteine-mediated redox networks in a range of biological processes and adaptive responses in physiology and pathophysiology.

'' Connecting the dots: how dynamic regulations output cellular functions '' Dr Lisa Van den Broeck Plant and Microbial Biology Department North Carolina State University Raleigh USA Thursday, October 20, 2022 11:00 Plants are challenged by a constantly changing environment. In response to these environmental signals as well as developmental cues, plants will meticulously adjust and finetune their growth. To manipulate plant growth, it is thus key to understand the regulations that integrate these signals and elicit a timely and coordinated response. Through probabilistic and machine learning inference methods, we have identified central regulators during development in Arabidopsis, tomato, pepper, and soybean. However, studying dynamic regulations in non-model species appeared challenging as a result of poor functional annotation of regulatory proteins. To overcome such limitations, we leveraged the advantages of artificial intelligence to predict protein function or sequence domains, including transcriptional activation domains. Finally, to further dissect the cellular signals in changing environments, we have established a framework for 3D bioprinting plant cells to study cell viability, cell division, and cell identity. The framework established here paves the way for a general use of 3D bioprinting for studying cellular responses in a tunable environment.

Dear all, Unfortunately The seminar of Jiri Friml is postponed due to covid. Kind regards, Delphine Van: "Delphine Verspeel" <delphine.verspeel@psb.vib-ugent.be> Aan: "meetings" <meetings@psb.vib-ugent.be> Verzonden: Vrijdag 30 september 2022 18:02:02 Onderwerp: You are invited to attend “Auxin signaling: more than we could ever imagine” ON October 14, 2022 You are receiving this e-mail because you subscribed to our seminars announcements and reminders service at [ https://maillist.psb.ugent.be/mailman/listinfo/seminars | https://maillist.psb.ugent.be/mailman/listinfo/seminars ] . '' Auxin signaling: more than we could ever imagine '' Prof Jiri Friml Institute of Science and Technology Austria (ISTA) Klosterneuburg AUSTRIA Friday, October 14, 2022 14:00 The plant hormone auxin is a versatile intercellular signal influencing virtually all aspects of plant life. It has a unique ability to be directionally transported within tissues forming local auxin maxima or gradients that are central to many developmental processes mediated by auxin. One of the key roles of auxin is adaptation of plant growth to gravity, where shoots bend up and roots down. This paradox is based on opposite responses of these organs to the phytohormone auxin, which promotes cell expansion in shoots, while inhibiting it in roots via an unclear signalling pathway and yet unknown downstream cellular mechanism. The well-established canonical auxin signalling involving the TIR1/AFB auxin receptors, Aux/IAA repressors and ARF transcription factors acts in nucleus and mediates gene transcription. However, auxin also triggers cellular responses within seconds or minutes, too fast to rely on transcription. Part of the rapid responses is mediated by the non-transcriptional branch of the TIR1/AFB signalling, but others involve a yet completely unknown mechanism. Here Prof Jiri Friml will present new and surprising insights into the mechanism of auxin signalling including an ultrafast auxin-triggered protein phosphorylation response and previously unsuspected aspects of TIR1/AFB auxin perception and downstream signalling. Keywords : Auxin, Arabidopsis, root gravitropism, TIR1/AFB signalling Acknowledgements : Prof Jiri Friml gratefully acknowledges all present and past members of the Friml group and their excellent collaborators.
