Advances in biological nitrogen fixation and microbial technologies for tropical plants
1stDecember 2021 (14:00 – 17:00, CET)
The search for a more sustainable agriculture is leading to a growing demand for microbial-based technologies. In parallel, the recent advances in the study of microbiomes are revealing the complexity of the role of microorganisms. Among these, are nitrogen-fixing bacteria, which are able to associate beneficially with crops that are critical for human consumption notably, including legumes and grasses.
This webinar aims to present some recent developments in this field. We will start by addressing the recent discovery of underlying mechanisms involved in the legume-bacterium interaction (Eric Giraud). Then, we will focus on the example of the common beanrhizobia(Ederson Jesus) and its microbiome (Ashley Shade), and learn about the selection of ammonium-excretingAzospirillumstrains for the inoculation of grasses (Emanuel Maltempi de Souza). Finally, we will end the seminar hearing about the experience of microbial inoculation in Brazil and its business perspectives (Solon Cordeiro de Araujo), whose model is the inoculation of soybeans, but that has been expanding to other crops in the country.
