We are moving to Australia!!!

Prof. Kronzucker has accepted the position of Head of School of BioSciences at the University of Melbourne, Australia’s top research university (new email address: herbert.kronzucker@unimelb.edu.au). We hope to have our new lab up and running by the Canadian fall (the Australian spring) of 2017. New student and postdoc applications should be directed to: herbert.kronzucker@unimelb.edu.au. Our home will be the ‘Bio21’ Molecular Science and Biotechnology Institute of the University of Melbourne, and we are excited to be next door to a group of truly exceptional research teams: http://www.bio21.unimelb.edu.au. We are looking forward to our new life by the waters of Port Phillip Bay, in one of the world’s most liveable cities :).

Declining soil fertility, increasing soil salinization, and a burgeoning human population have led to severe strains on the world's agricultural systems. A key factor in the relief from such strains is the better understanding of plant responses to soil nutrients and toxicants, and the application of this understanding to the improvement of cultivars and farming practices. Our laboratory seeks to directly engage in this urgent mission, by use of a combination of physiological approaches designed to address questions of ion acquisition and stress tolerance at cellular and whole-plant levels, in the world's most important plant species.

We examine the role of nutrient ion fluxes at cellular, whole-organism, and ecosystem levels, focusing on yield potential in cereals, cellular ionic interactions, and drought and salt stresses. Our approach is multidisciplinary, ranging from mathematical modelling to radiotracing of ion fluxes and ecological analyses in the field. The techniques we use include the subcellular tracing of ion fluxes and compartmentation, the genetic manipulation of plant metabolism and nutrient acquisition, electrophysiology, gas exchange, ionic and metabolic profiling of tissues, and analyses of plant growth and yield. We strive to investigate the physiology of intact model and non-model organisms, and develop methods to tackle the complexity associated with whole systems.

Our research program has attracted over 10 million dollars in research funding since 1999, and has been supported by The University of Melbourne, The University of Toronto, The Natural Sciences and Engineering Research Council of Canada (NSERC), the Canada Research Chair (CRC) program, the Canadian Foundation for Innovation (CFI), and Canada's national Green Crop Network (GCN), aimed at increasing greenhouse gas capture through biological means. Our international collaborative partners include The International Rice Research Institute, The University of Copenhagen, The University of Bonn, The Technical University of Munich, and The Chinese Academy of Sciences. In Canada, we have formed partnerships with diverse groups, including, in Toronto, the Canadian Association for Mental Health (CAMH), the Centre for Global Engineering (CGEN), the Dalla Lana School of Public Health, St. Michael's Hospital, and the Institute for the History and Philosophy of Science and Technology (IHPST); in Vancouver, the Tri-University Meson Facility (TRIUMF); in London, the BIOTRON facility at Western University; and in Quéc City, the University of Laval.

Herbert Kronzucker is a researcher at the University of Toronto's Scarborough Campus who is leading a team of researchers who are trying to help solve the problem of world hunger by developing a type of rice that can thrive in salt water.

Recent work from our lab, including a publication in Nature Plants, has been featured in The University of Melbourne's Pursuit magazine.
Our work on rice has been featured on the front page of Canada's national newspaper, The Globe & Mail.

Toronto Life Dec 2009 Our research has been featured in numerous spapers, magazines, television and radio broadcasts (including CBC, Radio Canada, CTV, Global TV, Fairchild Television, and the Weather Channel), a cover article in Toronto Life magazine, and the 2010 G20 Conference in Toronto, where it was hailed as among the city's greatest "life-changing and life-saving discoveries." Also, see our recent article on rice in Zoomer Magazine (June 2015 issue).

Our lab group's contributions to editorial activities at the Journal of Plant Physiology have been recently highlighted in the Bulletin of the Canadian Society of Plant Biologists (CSPB), which can be found here.

Our 2016 study in the journal New Phytologist has been covered in more than 300 international news outlets, including coverage by the American Association for the Advancement of Science (AAAS), the Global Plant Council, the New Phytologist Trust, Science Daily, Science Newsline, The Times of India (the world’s largest English-language daily), The Economic Times (the world's largest business newspaper after the Wall Street Journal), Google News, Yahoo!
