Annual McCully Lecture
杏吧原创 University has recently initiated an annual lecture series in honour of plant scientist, Dr. Margaret E. McCully, who was an extraordinary teacher and faculty member in the 杏吧原创 Biology Department for close to 35 years. Following her retirement in 1999, she moved to Australia where she continued her work. She is currently an honorary research scientist at CSIRO and visiting fellow at the Australian National University in Canberra. Margaret is internationally recognized for her pioneering work in microscopy and root anatomy and physiology. 聽The annual McCully lecture in Plant Biology is held in each year in the Spring. The theme of this lecture series is 鈥渇rom the lab to the field鈥�.

Exploring the biology and biotechnology of lignin
April 25, 2025
is an Assistant Professor in the Department of Biology at the University of Ottawa. He received his PhD from the University of British Columbia where he worked with Professor Shawn Mansfield to study lignin biosynthesis in poplar. Following his time in Vancouver, Yaseen moved to Finland where he worked as a University Researcher at the University of Helsinki. He moved back to Canada in 2024 to start his own research programme at the University of Ottawa. Yaseen studies lignin from both basic science and applied viewpoints, using a variety of molecular biology, bioimaging, and analytical chemistry tools. His work aims to elucidate the mechanisms driving cell wall formation and lignification in diverse taxa, and to use these insights to improve the performance of plants in industry and agriculture.
Modifying the plant cell wall from the inside out.
April 26, 2024
is an Assistant Professor and Canada Research Chair in Plant Cell Biology at the University of Toronto. Her ground-breaking research uses advanced microscopy tools to investigate mechanisms of cell wall synthesis, secretion, signaling and remodelling with a view to improving plant biomass for food, materials and energy. Heather earned her PhD working with Lacey Samuels at the University of British Columbia where she studied the transport of lipids that form the protective plant cuticle. After her PhD, she joined the Max Planck Institute for Molecular Plant Physiology (Germany) to study cell wall synthesis as an EMBO postdoctoral fellow with Staffan Persson. Heather moved with the Persson lab when they relocated to the University of Melbourne (Australia). There, she was awarded an Australian Research Council Discovery Early Career Researcher Award to continue her work on cell wall signaling. Heather joined the Department of Cell and Systems Biology at the University of Toronto as a Canada Research Chair in Plant Cell Biology in July 2019. Outside the lab, Heather is an ice hockey enthusiast and opera fanatic.
Exploring deep evolutionary patterns and processes in eukaryotes through the lens of genomics
April 21, 2023
, Professor of Biochemistry and Molecular Biology at Dalhousie is a fellow of the . Dr. Slamovits obtained his doctorate from the Universidad de Buenos Aires in 2002 followed by post-doctoral work at the University of British Columbia until 2009. Dr. Slamovits has an interdisciplinary research program that examines the molecular evolution and cell biology of single-cell eukaryotes 鈥� commonly called protists.聽 Protists are microscopic in size but represent the greatest part of eukaryotic diversity 鈥� a vastly understudied group that form a major part of ecosystems. Dr. Slamovits鈥� group assembles and analyzes the genomes of mainly marine protists to explore interesting questions related to evolution and relationships like endosymbiosis and parasitism. His pioneering work has exposed the far reaches of algae and the green tree of life. Click to listen to a recording of the talk.
Understanding Complex Trait Evolution: A Case Study with C4 photosynthesis
April 8, 2022
, Professor of Ecology and Evolution at the University of Toronto. Dr. Sage obtained his doctorate from the University of California, Davis in 1986 and conducted post-doctoral studies at Desert Research Institute in Reno, Nevada from 1986-1987. He has been at the University of Toronto since 1993. His research addresses how plants are adapted to changing climates and atmospheric carbon dioxide levels. A well-known aspect of his work is the study of novel photosynthetic pathways 鈥� particularly the evolution of C4 photosynthesis. Evolution of this trait involves changes in leaf anatomy and physiology occurring dozens of times in flowering plants. Understanding the evolution of this complex trait provides a road map for the engineering of highly productive crops compatible with changing climates.
Reprogramming root cells for arbuscular mycorrhizal symbiosis
April 26, 2019
, Boyce Thompson Institute for Plant Research, Cornell University. Dr. Harrison received her B.Sc. degree from the University of Newcastle Upon Tyne, UK in 1984 and her Ph.D. from the University of Manchester Institute of Science and Technology in 1987. In 2003, Dr. Harrison was appointed to the Boyce Thompson Institute at Cornell University where she is William H. Crocker Professor. Dr. Harrison is a pioneering plant biologist who studies how plants and fungi form symbiotic relationships to trade crucial nutrients that promote the survival of both species. She is especially well known for her work on arbuscular mycorrhizal soil fungi, which adopt a relationship with an estimated 80% of vascular plant families. Ultimately, this basic understanding will make it possible to better deploy symbiosis in the field for sustainable agriculture.
Redefining the metabolite-rich trichomes of聽Cannabis sativa听蹿濒辞飞别谤蝉
April 27, 2018
聽University of British Columbia. Dr. Samuels received her B.Sc. degree from McGill in 1984 and her Ph.D. from UBC in 1989. After completing a post-doc at the University of Colorado, she obtained a faculty position at UBC in 2001. She went on to become Chair of the Botany Department and is a full professor. Dr. Samuels is a celebrated cell biologist whose innovative work using microscopy pushes boundaries in understanding how plant cells synthesis and secrete cell walls and surface coatings. More recently, Dr. Samuels has been delving into the cell biology of secretory trichomes found on the flowers of Cannabis sativa, which harbor a vast array of metabolites like terpenes and cannabinoids whose therapeutic functions we are only starting to understand.
Why do legume root nodules evolve hydrogen gas?

. St. Mary’s University, Halifax. Dr. Dong received his B.Sc. from Shaanxi Normal University in 1981, M.Sc. from Peking University in 1987, and Ph.D. from 杏吧原创 University in 1995. Dr. McCully and Dr. Canny were his Ph.D. co-supervisors. Dr. Dong is a now a professor in the Biology Department at St. Mary鈥檚 University in Halifax. His research focuses on inter-relationships between root systems and rhizosphere organisms. This work is aimed at developing renewable bio-products as an environmentally friendly alternative to chemical fertilizers in agriculture.

Dr. Plaxton is now a professor in the Biology Department at Queen鈥檚 University in Kingston. He holds a Queen鈥檚 University Research Chair in Plant Biochemistry. He is widely considered one of the finest plant biochemists in Canada. His research focuses on understanding the organization and control of plant carbohydrate metabolism and the biochemical adaptations of phosphate-starved plants. Application of this work has the potential to reduce reliance on chemical fertilizers and boost production in crops.
