A scientist will speak in the US about the possibility of creating decaffeinated weed

In February, missionary researcher Maximiliano Rossi will present his doctoral work on the presence of caffeine in Yerba Mate at the University of Michigan, United States, and other institutional settings.

The work was carried out by the National University of Missiones (UNAM) con collaboration with the University of Michigan and the University of Buenos Aires (UBA)started in 2017 and finished in 2023.

“Knowing about these genes will allow us to find yerba mate plants that naturally produce more or less caffeine, which also affects the taste, more intense if there is more caffeine, or more mellow if very little, and produce decaffeinated. plants for those with caffeine intolerance,” said Rossi.

And he added: “The study has an application in production, because, with this knowledge, a yerba mate producer will be able to identify plants with high, medium or low levels of caffeine and make them clonally, to create different flavors, which will also depend on the growing conditions”.

The laboratory of the University of Michigan is a pioneer in caffeine research in plants, such as guarana, cocoa, tea and coffee, and now yerba mate, so it was interested and supported Rossi’s work with a grant.

she The goal of Rossi’s work is to discover the genes involved in the production of caffeine in yerba mate.three, an initiative that emerged from UNAM researchers, such as Dr. Pedro Zapata, Dardo Martí and others.

Within the framework of the research, the complete genome of the yerna mate plant was sequenced, thanks to the work of the UBA, thanks to the PRO MATEAR consortium, where INYM, the Ministry of Science of the Nation, the Ministry of Education and Science of Missiones, the OTHER, and the FIRST. The DNA sequencing was done in the USA and Brazil, and it was assembled in Argentina.

Maximiliano Rossi is a 41-year-old professional, with a degree in Genetics, a doctor in Biotechnology, a secondary and tertiary teacher, and a member of the Science and Research team of the Ministry of Education of Misiones.
