Abstract Submission

Submit abstracts by February 14, 2025

Guidelines for Abstracts:

1. The body of the abstract (not including the title, author names, and affiliations) is limited to 300 words. An abstract should contain an introduction to the subject and description of the problem, objectives, brief results, and conclusions. The abstract should be concise with just enough information to introduce your subject and generate interest. "Research Proposal", abstracts should have a background and objectives.

2. Include a brief but descriptive title. Include all authors who have contributed to your research and indicate the affiliations of each author using a number corresponding to their institution listed below. The main (presenting) author's name should be marked with an asterisk (*). Include a correspondence email (usually the presenter, but can also be the supervisor or other figure).

3. Abstracts should written in 12 pt. Calibri, single spaced. Scientific authorities are to be given for all Latin names the first time they are mentioned in the body of the abstract. Cultivar names are to have single quotation marks around them every time they are mentioned. All abbreviations are to be spelled out in full the first time they are mentioned in the body of the text.

4. Abstracts must be submitted as either Word documents (.docx) or PDF documents (.pdf) with a specific naming format which helps us with organization!

FILE NAMING FORMAT: LASTNAME_Firstname_Abstract

5. Oral presentations will be 12 minutes + 3 minutes for questions - please check the program for updates on your session times. Poster presenters will be required to be attend their posters from (#:## PM - #:## PM on March 14th and #:## PM - #:## PM on March 15th).

Mapping of quantitative trait linkage (QTL) in Brassica napus L. for tolerance to excess moisture stress

Among different forms of abiotic stress, excess moisture impacts growth and development and causes yield losses in the Brassica napus L. ranging from 30-45%. Among the consequences of excess moisture are oxygen limitation, as well as reduction in photosynthesis, and nutrient uptake. Limited photosynthesis rate is ascribed mainly to dysfunctions in the electron transport chain in chloroplasts as a result of oxygen depletion. Plants experiencing excess moisture also exhibit lower germination rate, stunted growth, decreased yield and in extreme cases, death of the plant. The aim of this project is to study excess moisture tolerance in B. napus and map the genes responsible for tolerance using quantitative trait linkage (QTL) techniques. My hypothesis is that quantitative trait loci will be discovered at the sites of genes encoding secondary metabolites, as well as metabolites related to reactive oxygen species scavenging, oxidation reduction, and regulation of transcription and translation. The objective will be achieved by developing a doubled haploid (DH) population from two crosses between a sensitive and tolerant parent and then phenotyping the progeny to determine each genotype’s tolerance or sensitivity to excess moisture. The individuals will then be genotyped using the 60k SNP BeadChip Array and then analyzed for QTL. Results from this project will assist researchers in understanding B. napus tolerance in excess moisture conditions and provides a key opportunity to identify candidate genes through high-coverage analysis.
