Plant Adaptation to Extreme Environments

Hugo Zheng
Session Chair

As sessile organisms permanently restricted to their site of germination, plants have developed, over the course of evolution, unique mechanisms that allow them to thrive in the environment without moving. In this session, we will first talk about how plants sense their environment in the rhizosphere, and then discuss how plants response to unfavorable environments at the subcellular level. We will also discuss novel genomic and genetic tools by which we can manipulate crops to improve agriculture in the face of rapid climate change

Decoding plant signals in the rhizosphere

Strigolactones (SLs) act as endogenous hormones that sculpt plant architecture and exogenous signals in the rhizosphere. I will discuss how SLs trigger germination of Striga, a devastating plant pest that parasitizes crops. I will also describe how we used yeast as a model system to elucidate how fungi sense SLs.

Stress unfolded: When Proteins Misfold, Plants Adapt

The endoplasmic reticulum (ER) is essential for protein synthesis, folding, and stress adaptation. This presentation will highlight recent discoveries on how the plant ER senses and responds to environmental stress while sustaining protein production, revealing key mechanisms that maintain cellular homeostasis and promote resilience under adverse conditions.

Ubiquitin System in Stress Response

Affiliation: Heidelberg University, Centre for Organismal Studies

Evolutionary Origins & Mechanisms of Cellular Quality Control

Summary of the talk: In this talk, I will present our selective autophagy receptor discovery pipeline and show how we use cross-species comparisons to map the architecture of selective autophagy networks. I will highlight the discovery of new receptor–cargo modules and pathways that reveal how cells safeguard proteome and organelle integrity under stress.

Prescriptive breeding: a next-generation paradigm for crop improvement

Prescriptive breeding defines an ideotype tailored to specific environment and cropping system, recognizing that complex G×E×M interactions make a universal cultivar unrealistic. This approach is increasingly vital as population growth, rising demand for sustainable, nutritious foods, and climate and resource pressures intensify challenges for agriculture.

Shelley Lumba

Assistant Professor, University of Toronto

Shelley Lumba is a plant molecular biologist whose work focuses on how plants sense and respond to chemical signals. Shelley is currently an Assistant Professor in the Department of Cell and Systems Biology at the University of Toronto. She has made significant contributions in elucidating the mechanisms of signalling pathways of plant hormones such as strigolactones and karrikins, helping to uncover how these signals shape seed germination and nutrient adaptation. Her recent publications highlight cross-kingdom chemical communication between plants and fungi. Through collaborative, interdisciplinary projects, Shelley aims to connect fundamental molecular mechanisms with broader ecological and agricultural questions.

Sophia L. Stone

Professor, Associate Dean Graduate Studies and Global Relations, Dalhousie University

Sophia Stone earned her PhD from York University (Ontario, Canada) and completed NSERC post-doctoral and Human Frontier Science Program (HFSP) long-term fellowships at the University of California-Davis, (California, USA). She is a Professor in the Department of Biology & Marine Biology at Dalhousie University (Nova Scotia, Canada), where she holds the George S. Campbell Chair in Biology. Dr. Stone is currently the Department Chair and was recently appointed as Associate Dean Graduate Studies and Global Relations for the Faculty of Science. Dr. Stone has a long-standing research interest in the Ubiquitin Proteasome System (UPS), which controls a significant portion of eukaryotic proteome through selective proteolysis.

Her current research utilizes a combination of genetic, physiology, cell and molecular biology to understand how plants utilize the UPS to promote growth, development and tolerance of suboptimal growth conditions. Dr. Stone is the recipient of several research awards including the HFSP Career Development Award, the Faculty of Science Killam Prize (Dalhousie University), and the C.D. Nelson Award in Plant Biology from the Canadian Society of Plant Biologist (CSPB). Dr. Stone is passionate about increasing diversity in STEM and works with several university and community-based outreach initiatives aimed at encouraging the participation of women and individuals from underrepresented groups in STEM.

Yasin Dagdas

Heidelberg University, Centre for Organismal Studies

Yasin Dagdas is a Professor of Evolutionary Cell Biology at the Centre for Organismal Studies (COS), Heidelberg University. His research aims to uncover the fundamental principles by which eukaryotic cells preserve cellular integrity under stress. By integrating live-cell imaging, proteomics, structural biology, and comparative systems across plants and other eukaryotes, his group discovers conserved and lineage-specific mechanisms of selective autophagy and ribosome-associated quality control. His work reveals how cellular quality control directs fate decisions and organismal resilience. Before joining COS, he led a research group at the Gregor Mendel Institute (Vienna BioCenter).
