Brown Bag Seminar
Q-AOS Brown Bag Seminar Series The 219th Seminar “Community Ecology of Soybean Rhizobia and Mitigation of N₂O Emissions”
The Q-AOS Brown Bag Seminar Series will start every Wednesday at lunchtime from April 2021. The purpose of this webinar series is to provide opportunities not only to learn research related to SDGs in Asian and Oceanian regions, but also to expand your research network across different academic areas.
The webinar is free, available in English and Japanese, and open to everyone! We hope you all come and join us!

Abstract
Soybean-nodulating rhizobia infect soybean roots to form root nodules, which are symbiotic organs. Once inside the nodules, the bacteria obtain energy from the host soybean and fix atmospheric nitrogen, supplying the host with ammonia. Through this symbiotic nitrogen fixation, soybeans can grow healthily even under low-nitrogen conditions. Rhizobia inhabiting soils exhibit different genotypes along environmental gradients.ln converted paddy fields, the rhizobial species that become dominant show high nitrogen-fixing activity and possess all the enzymes required for nitrate respiration(denitrification), making them beneficial strains that do not emit nitrous oxide(N2O), a potent greenhouse gas. By utilizing such advantageous rhizobia, it becomes possible to achieve soybean production that maintains yield while avoiding greenhouse gas emissions.
