Imaging endomembrane dynamics in plants

Published: 2023-09-07

Imaging technologies support research into the structure and function of plants, shed light on plant health, resilience and adaptability, and help answer agroecology-related research questions. The Euro-BioImaging User Forum “Understanding Plant Biology” will showcase how imaging supports cutting edge research in this domain and provide information on funding opportunities for agroecology-related research projects via the AgroServ project. At this event, our keynote speaker, Marisa S. Otegui of the Department of Botany, University of Wisconsin-Madison, will present “Imaging endomembrane dynamics in plants.” Full abstract below. 

What: Euro-BioImaging User Forum “Understanding Plant Biology”

When: October 12, 2023, from 14:00-17:00 CEST

Where: Online

Imaging endomembrane dynamics in plants 

Marisa S. Otegui, Department of Botany and Center for Quantitative Cell Imaging, University of Wisconsin-Madison

The dynamic flow of proteins at the plasma membrane is tightly regulated and crucial for a cell to fine-tune its downstream signaling pathways. Maris S. Otegui and her team are using a combination of light and electron microscopy modalities to understand the mechanism controlling two important catabolic pathways in plants, autophagy and the endosomal sorting. They have identified new receptors controlling the autophagic degradation of organelles, such as the endoplasmic reticulum and chloroplasts. They have also applied novel imaging approaches to understand the membrane vesiculation profiles of multivesicular endosomes of several plant and plant-related lineages. This analysis has allowed them to develop a model of the evolutionary steps leading to the unique protein-sorting properties of plant endosomes. Dr. Marisa S. Ortegui will discuss the challenges and opportunities in plant imaging to further advance our understanding of critical cellular processes as a Keynote Speaker at the Euro-BioImaging User Forum on plant biology.
