'' New insights in the root apical meristem maintenance and lateral root development in Arabidopsis thalian a '' Prof Joseph G. Dubrovsky Department of Plant Molecular Biology Institute of Biotechnology National Autonomous University of Mexico (UNAM) MEXICO Monday, May 22, 2023 11:00 Root system possess a modular organization, in which the root apical meristem (RAM) maintenance and root growth are essential for new root formation. In my lab we study the RAM maintenance and lateral root (LR) formation, and I will discuss our recent discoveries and novel understanding of some processes related to the root system formation. In search of new regulatory pathways of RAM maintenance, we isolated several mutans that are incapable of root growth. This work revealed a new metabolically-dependent regulatory pathway involved in RAM maintenance. Specifically, we established that THREONINE SYNTHASE 1 (TSY1) is critical for stem cell activity independently of the classical SHR-SCR, PLT , and WOX5 regulatory pathways. Using mathematical modeling we were able to reproduce in silico determinate root growth in loss-of-function mutants and predict that not only synthesis but also catabolism of Thr is essential for the RAM maintenance. This work also demonstrated that the RAM proliferation and transition domains can be uncoupled. The RAM function is fundamental for the new root axis and LR root formation, and in the second part of my seminar I will present new insights that show that LR does not start from a preselected group of cells, but in most cases from a single founder cell (FC). We established that after specification of the first FC, a dynamic and non-stereotypic process of FC recruitment from neighboring pericycle cells is taking place. FC recruitment occurs in longitudinal and tangential directions and culminates in the formation of a morphogenetic field of FCs. The recruitment of phloem-pole pericycle to FCs and the role of parent root tissues in the LR formation will also be discussed. I will present our recent data that show how parental root procambium in the vicinity with the FCs participates in the formation of the xylem bridge underlying vascular continuity between all root types in the root system.

"Developing precision breeding-by-demand toolboxes: The grass pea case study" Dr M. Carlota Vaz Patto Genetics and Genomics of Plant Complex Traits Laboratory (PlantX Lab) ITQB NOVA PORTUGAL Thursday, April 20, 2023 11AM Consumers worldwide are increasingly concerned with food quality, environmental sustainability and, after COVID19 pandemic disruption of long food supply chains, with food security. Protein-rich and environmentally friendly legumes, locally produced, like grass pea (Lathyrus sativus L.), are an excellent answer to these concerns. Although Portugal holds promising food legumes genetic resources, a reduction in local production and consumption in the country, as well as in Europe most traditional markets occurs. Reduced investment in breeding, particularly in nutritional/organoleptic quality, resulted in overall unattractiveness of current varieties not only to farmers/processors but also to consumers and to this national resource underuse. To increase food legumes consumption and cultivation, breeding objectives and market preferences should be better aligned. With the development of high-throughput genetic and phenotypic technologies, it is now possible to address breeding in a more integrated way. At the PlantX Lab, we collect and integrate multiple layers of biological information (metabolomics, phenomics, genomics) through statistical genomics, assuring an improved understanding of this complex biological system, and higher prediction accuracy for target phenotypes, such as yield and quality (through genotype-to-phenotype prediction models). During this presentation, I will revise the work developed on grass pea agronomic, biotic and abiotic stress resistance genetic basis and introduce the more recent nutritional and organoleptic quality studies on the same species. The developed molecular toolbox based on these prediction models will be important for food legumes genotyping, product screening (e.g. quality assessment of legume batches), and marker-assisted selection for routine implementation of quality breeding objectives within the more often focused agronomic improvement.

''Intracellular membrane trafficking – a ubiquitin point of view'' Prof Erika Isono Chair of Plant Physiology and Biochemistry Department of Biology University of Konstanz GERMANY Thursday, March 23, 2023 11:00 Intracellular trafficking is essential for plant growth, development, and environmental responses. Ubiquitin family proteins are small modifier proteins that are conjugated to proteins and lipids and serve as targeting signals in endosomal and autophagosomal trafficking processes. Thus, for the proper regulation of endosomal and autophagic protein degradation, the spatiotemporal regulation of ubiquitylating and deubiquitylating enzymes as well as ubiquitin-binding proteins is essential. Prof Isono her group is interested in the molecular mechanisms of the regulation and recognition of ubiquitin and ubiquitin-like proteins in intracellular trafficking. They have identified deubiquitylating enzymes (DUBs) that are important for fine-tuning the ubiquitin- and endosomal sorting complex required for transport (ESCRT)-dependent degradation of plasma membrane proteins. Furthermore, they have found proteins that interact with the ubiquitin-like protein ATG8 on autophagosomes and could be key for the recruitment of the ESCRT machinery to non-endosomal membranes.

Many of these processes are associated with membraneless organelles, dynamic structures formed by multivalent interactions of proteins and nucleic acids that may exhibit properties of liquid-liquid phase condensates. In his presentation Dr Karel Riha will explore the role of P-bodies, cytoplasmic biocondensates sequestering translationally repressed mRNA and RNA decay proteins, in plant germline differentiation and stress response.

'' MAP Kinase Signaling in Cell Polarity - a Lesson from the Plant Embryo '' Prof Martin Bayer Center for Plant Molecular Biology (ZMBP) Developmental Genetics University of Tübingen GERMANY Thursday, January 26, 2023 11:00 Breaking symmetry by asymmetric cell divisions is essential for establishing different cell identities in multi-cellular development. Cell-cell signaling by receptor kinase/MAP kinase signaling pathways seems to be a reoccurring mechanism in polarizing plant cells and establishing different cell identities in the daughter cell of asymmetric cell divisions. We are using the early plant embryo as system to study initial events in cell polarization by the ERECTA-YODA signaling pathway – a prototype receptor kinase/MAP kinase signaling pathway. Embryogenesis resembles a linear system of developmental progression with successive asymmetric cell divisions that produce the primary tissue types of the plant seedling and establish the stem cell niches of the shoot and root. By comparing the function of the ERECTA-YODA pathway in the embryo with its role in planar patterning of the leaf epidermis, we identified principal functions of a core pathway and context-specific modifications. We present new data on the impact of polar YODA activation on early embryonic patterning and shed light on the mechanism and evolution of distinct modes of YDA activation in the zygote on a molecular and structural level. We furthermore discuss possible benefits of different modes of YDA activation and their distinct parent-of-origin effects.

They have identified deubiquitylating enzymes (DUBs) that are important for fine-tuning the ubiquitin- and endosomal sorting complex required for transport (ESCRT) - dependent degradation of plasma membrane proteins. Furthermore, they have found proteins that interact with the ubiquitin-like protein ATG8 on autophagosomes and could be key for the recruitment of the ESCRT machinery to non-endosomal membranes.
