Nancy Soni is a Ph. D Candidate from McGill University. She is a winner of the 2019 U of Guelph Plant Sciences Symposium Travel Grant, and will be presenting her research using QTL sequencing and metabolo-genomics to identify wheat resistance R genes against Fusarium head blight disease.
Abstract: Fusarium head blight (FHB) is one of the devastating diseases of wheat worldwide. Over a hundred FHB resistance QTL identified, of which the QTL-Fhb1 represents the most studied source of resistance in wheat breeding programs. Consequently, several resistant genes were identified and functionally validated, but the knowledge regarding the resistance mechanisms is still limited. A combined metabolo-genomics approach was employed to identify FHB resistance genes, especially those that are involved in the biosynthesis of metabolites. The QTL regions of Near Isogenic Lines (NILs) with resistant and susceptible QTL-Fhb1, derived from Sumai 3*5/Thatcher crosses sequenced based on Illumina HiSeq next-generation sequencing identified a total of 37 putative genes. Among these, TaLAC and TaNAC were selected as a potential candidate gene based on the presence of functional SNPs, metabolic profiles of near-isogenic lines, and the gene expression study. These two were further silenced using virus-induced gene silencing (VIGS) for functional analysis. The silenced samples were analyzed for fungal biomass, disease severity, gene expression, metabolic profiling, and biochemical analysis. Moreover, ab-initio docking was also performed for both the genes speculating their possible interaction and involvement in gene regulatory network. Based on our research, we have found the involvement of NAC transcription factor in regulating the expression of downstream secondary cell wall biosynthetic genes such as laccase (TaLAC) and laccase consequently involved in lignin polymerization, thus reinforcing phenylpropanoid pathway. In conclusion, resistance genes polymorphic in susceptible cultivars can be genetically engineered for durable FHB resistance.
Haily MacDonald is a feminist activist and currently Director of Operations at Huronia Transition Homes, a non-profit in Simcoe County working to end all violence against all women. Haily was one of the co-creators of Operation Grow, a holistically designed social enterprise dedicated to reducing poverty, food scarcity, isolation and the impacts of trauma in the lives of women. She holds a joint BA in Women & Gender Studies, and International Development, and is currently completing her Masters in Interdisciplinary Studies; her research focuses on Operation Grow as an effective community development model to support women who have experienced violence. Operation Grow is a social enterprise based out of Midland, ON. They operate as a hub which includes a vertical farm, a community kitchen, a yoga and meditation hall, and shower and laundry facilities. They are addressing plant sciences while looking through the lens of innovation and accessability to address the needs of women who have experienced violence.
Nathan Nordstedt is a Ph. D Candidate from Ohio State Univeristy. He is a winner of the 2019 U of Guelph Plant Sciences Symposium Travel Grant, and will be presenting his research on mitigating drought stress via the application of growth promoting rhizobacteria.
Abstract: Abiotic stress negatively impacts horticulture crop quality and value by causing stunted growth and reduced flowering. As resources become limited, growers need sustainable tools to reduce inputs without sacrificing crop quality. Plant growth promoting rhizobacteria can stimulate plant growth during abiotic stress by enhancing nutrient uptake and regulating plant hormone levels. An in vitro bioassay identified 11 Pseudomonas strains that withstand high levels of osmotic stress, a trait correlated with the ability to confer drought tolerance in plants. Greenhouse trials were developed to evaluate these strains to stimulate plant growth under drought and low-nutrient conditions. Three of the 11 strains increased flower number and plant biomass when applied to Petunia × hybrida under both abiotic stress conditions. These strains were validated in a greenhouse trial to stimulate plant growth under abiotic stress of three economically-important species: P. hybrida, Impatiens walleriana, and Viola × wittrockiana. Drought and low nutrient trials were conducted on plants treated with each of the three bacteria strains. Application of each of the three strains resulted in an increase in shoot biomass for all three species under both drought and low nutrient conditions. The bacterial treatments also resulted in visibly higher quality plants with higher tissue macronutrient content when grown under low nutrient stress. All three bacteria strains also increased flower number in P. hybrida after recovery from drought stress. This work provides a unique system to increase the health, quality, and overall value of horticulture crops grown under multiple abiotic stresses in a greenhouse production system.
Dr. Marcel Schlaf is a professor in the Department of Chemistry at the University of Guelph. The research he has focused on includes biomass conversion through selective deoxygenation. What's does that mean, and how does it relate to plant sciences? The objective of their research is to use renewable biomass, (i.e., carbohydrates & sugars) and their derivatives (e.g., furanics such as furfural) as carbon sources to make the same chemicals we now make from crude oil. For example, making the components of NYLON from corn sugar or components of polyurethane foams or high-energy density jet-fuel from corn cobs - rather than crude oil. By using the by-products of the agricultural and forestry industries, they can use renewable carbon sources to create "drop-in" technology for existing large-scale chemical processes based on fossil carbon sources - and we are talking potentially megatons/years here!!

The University of Guelph Plant Sciences Symposium (PSS) is an event that embraces diversity and is committed to providing a safe and productive meeting environment. The goal of the meeting is to foster open dialogue and exchange of scientific ideas, to promote equal opportunities and treatment for all participants, in an environment that is free of harassment and discrimination. All meeting participants are expected to treat others with respect and consideration.
The organizers of PSS are committed to supporting a productive and safe environment for all attendees, presenters, and guests at the 2019 Symposium. As such, we prohibit any form of harassment, which includes speech or behaviour that is not welcome or is personally offensive, whether it is based on ethnicity, gender, religion, age, body size, disability, veteran status, marital status, sexual orientation, gender identity, or any other reason not related to scientific merit.
The PSS organizing committee reserves the right to remove an individual from the 2019 symposium without warning.
The meeting organizers encourage meeting attendees to share their 2019 PSS experience through social media. For Twitter, we suggest using the hashtag #plantscisymposia. Speakers and poster presenters have been advised that PSS encourages sharing through social media, and therefore we will be using an “opt-out” approach. Unless explicitly stated by the presenter, all presentations can be shared via social media. If a speaker or poster presenter does not wish to have their research shared via social media, please respect their requests.
Concerns about these policies should be directed to the 2019 PSS organizing committee at: email@example.com
