Metabolomic Insights Into Soybean Defense Strategies Against Diverse Pathogens

Soybean, as a globally critical leguminous crop, faces continuous threats from different pathogens, which profoundly affect global production. Although the genetic interactions between soybean and pathogens have attracted extensive attention and research, the complex biochemical responses remain poorly understood. Qiu Min and colleagues decided to use targeted and untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics to dissect the intricate interactions between soybean and various pathogens.

The team identified a total of 627 featured metabolites in infected  samples, which were clustered into four modules covering , isoflavonoids, triterpenes,  and peptides, and other compounds such as phenols. Researchers found significant changes in both primary and secondary metabolism in response to pathogen invasion.

The bidirectional changes in total flavonoids across diverse pathogenic inoculations were particularly notable. Noteworthy among the highly inducible total flavonoids were known representative anti-pathogen compounds (glyceollin I), backbone forms of isoflavonoids (daidzein, genistein, glycitein, formononetin), and newly purified compounds in this study (prunin).

Subsequently, the authors further demonstrated the biological roles of these five compounds, validating their diverse functions against pathogens: prunin significantly inhibited the vegetative growth and virulence of Phytophthora sojae; genistein exhibited a pronounced inhibitory effect on the vegetative growth and virulence of Phomopsis longicolla; daidzein and formononetin displayed significant repressive effects on the virulence of P. longicolla.

Video: 2024 AGM Day 1 Panel - Succession Planning & Risk Management

Statistics Canada’s 2021 Census of Agriculture indicates that 75% of all farms operating in Canada operate as sole proprietorships or family partnerships. While incorporated farms make up just over a third of Canadian farm operations most of those are also family-run corporations. If the issue of farm succession planning is not on the minds of Canadian farm producers, it probably should be. That same Statistics Canada Census of Agriculture indicates that the average age of a Canadian farmer is 56 years of age with the 55 plus age group becoming the fastest growing segment in Canadian agriculture.

Despite these statistics, the same Census reports that only 1 in 10 Canadian farm operations have a formal succession plan. While each farm has its unique issues when it comes to transferring the business to the next generation, there are some common topics that almost all farmers must address. Join financial, legal, and tax experts to learn about how to begin the process, key tips on ensuring a smooth transition from one generation to the next, and how to manage the strong emotions the topic can create within the family.
