Widely consumed in South America, this remarkable plant is rich in diverse, bioactive compounds that contribute many health benefits.<\/p>\n\n\n\n<p>An international group of researchers has mapped the yerba mate genome, providing insights into the biosynthesis of caffeine in yerba mate. This new information provides opportunities for creating plant varieties with new characteristics.<\/p>\n\n\n\n<p>The work, led by the University of Buenos Aires, involved scientists from EMBL Hamburg and several institutes in Argentina, Brazil, and United States.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"a1\"><strong>Evolution of caffeine in yerba mate<\/strong><\/h2>\n\n\n\n<p>To uncover key aspects of yerba mate\u2019s genetic makeup, the scientists employed genome analysis. It revealed surprising facts about the plant\u2019s biochemistry and its evolutionary history \u2013 in particular, the evolution of caffeine biosynthesis.<\/p>\n\n\n\n<p>\u201cI discovered that an ancestor of yerba had duplicated its genome approximately 50 million years ago,\u201d said Federico Vignale, the study\u2019s first author and an EMBL Hamburg postdoc. \u201cThis ancestral duplication may have been key in the evolution of its metabolic complexity, allowing it to synthesise a wide range of bioactive compounds, such as terpenes, flavonoids, phenols, and xanthines, known for their antioxidant, anti-diabetic, and nervous system stimulant properties. Of all these compounds, my interest focused on caffeine.\u201d<\/p>\n\n\n\n<p>Caffeine is produced by several unrelated plant species, such as yerba mate and coffee, through similar metabolic pathways for its biosynthesis. Yet, the scientists discovered that the genes involved in these pathways evolved independently.<\/p>\n\n\n\n<p>\u201cWe came to understand in detail that the genes do not have a common ancestor, but come from separate origins, and that both yerba mate and coffee came to have caffeine biosynthesis by evolving along convergent pathways,\u201d said Adri\u00e1n Turjanski, the project leader and a researcher at the Institute of Biological Chemistry in the Faculty of Exact and Natural Sciences at the University of Buenos Aires (IQUIBICEN, UBA-CONICET).<\/p>\n\n\n\n<blockquote class=\"vf-blockquote | vf-u-margin__bottom--600 vf-u-margin__top--600\">\n  <div>\n    <div>\n      The parallel evolution of caffeine synthesis in yerba mate and coffee led scientists to suspect it plays a crucial role in plant survival, potentially functioning as a defence mechanism.    <\/div>\n    \n      <\/div>\n<\/blockquote>\n\n\n\n<p>Through detailed structural, experimental, and bioinformatic analysis, the scientists identified which pathways led to a specificity in caffeine biosynthesis that was different from the coffee plant.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"a2\"><strong>Paving the way for next-generation yerba mate<\/strong><\/h2>\n\n\n\n<p>The findings not only revealed yerba mate\u2019s evolutionary history, but they might also open opportunities to advance how it is cultivated.<\/p>\n\n\n\n<p>\u201cBy reading the genome you would know how to intervene and modify the plant,\u201d Turjanski said. \u201cOne could propose making it richer in certain characteristics, for example, a decaffeinated yerba mate, or one that is better adapted to other lands, and thus expand its cultivation.\u201d<\/p>\n\n\n\n<p>The team stressed that it is in this context that the foundation for this kind of work has been laid, so other groups working specifically with yerba mate can carry out new studies and, in turn, the industry can create new strains that either assist growers or satisfy user\u2019s tastes.<\/p>\n\n\n\n<p>For Vignale, the cultural significance of yerba mate in South America goes beyond its scientific implications, adding a deeply personal dimension to this research.<\/p>\n\n\n\n<p>\u201cYerba mate, for me, represents the most beautiful thing about the culture of my home country, Argentina \u2013 a drink that unites us, accompanies us, and is present in every moment of our lives,\u201d he said. \u201cThat&#8217;s why I didn&#8217;t hesitate for a second to accept the challenge. Sequencing the yerba mate genome felt, in a way, like sequencing Messi&#8217;s genome.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"a3\"><strong>Collaboration across continents<\/strong><\/h2>\n\n\n\n<p>The project was led by the <a href=\"https:\/\/exactas.uba.ar\/\">Faculty of Exact and Natural Sciences<\/a> at the University of Buenos Aires in collaboration with scientists from EMBL Hamburg, as well as <a href=\"http:\/\/www.iquibicen.fcen.uba.ar\/\">IQUIBICEN-CONICET<\/a>, <a href=\"https:\/\/www.unam.edu.ar\/\">Universidad Nacional de Misiones<\/a>, and <a href=\"https:\/\/www.unne.edu.ar\/\">Universidad Nacional del Nordeste<\/a> in Argentina; <a href=\"https:\/\/www.google.com\/url?sa=t&amp;source=web&amp;rct=j&amp;opi=89978449&amp;url=https:\/\/www.itv.org\/en\/home\/&amp;ved=2ahUKEwjZmtiMu-uKAxVgQPEDHX1eNAsQFnoECCAQAQ&amp;usg=AOvVaw0wx_NY9q1uivKB5Z9M_rg0\">Instituto Tecnol\u00f3gico Vale<\/a> in Brazil; and the <a href=\"https:\/\/www.igb.illinois.edu\/\">University of Illinois at Urbana-Champaign<\/a>, <a href=\"https:\/\/wmich.edu\/biology\/directory\/barkman\">Western Michigan University<\/a>, and <a href=\"https:\/\/www.plantsciences.ucdavis.edu\/\">University of California Davis<\/a> in the United States.<\/p>\n\n\n\n<p>To uncover the caffeine biosynthetic pathway in yerba mate, EMBL Hamburg provided key insights through structural modelling and molecular docking. The expertise provided by Vignale and his colleague Lucas Defelipe, members of EMBL Hamburg\u2019s <a href=\"https:\/\/www.embl.org\/groups\/garcia-alai\/\">Garc\u00eda Alai Team<\/a>, played a crucial role in this process.<\/p>\n\n\n\n<p>\u201cThis experience taught me the true value of interdisciplinary work and to grow together with scientists from different specialties,\u201d Vignale said.<\/p>\n\n\n\n<p>Vignale\u2019s first interaction with EMBL was through <a href=\"https:\/\/www.cabana.online\/index\">CABANA<\/a>, a project run by an international consortium of Latin American organisations and EMBL-EBI. Funded by the UKRI Global Challenges Research Fund, it aimed to <a href=\"https:\/\/www.embl.org\/news\/science\/open-data-latin-american-science\/\">strengthen bioinformatics capacity across Latin America<\/a> and supported research to address challenges faced by developing countries. The CABANA project itself aimed to tackle three global challenges: communicable disease, sustainable food production, and protection of biodiversity.<\/p>\n\n\n\n<p>Vignale added, \u201cthe CABANA project has not only strengthened my bioinformatics skills, which were essential for carrying out this research, but it also provided the necessary funding to complete the study.\u201d<\/p>\n\n\n\n<hr class=\"vf-divider\"\/>\n\n\n\n<p><em>This article has been adapted from a press release by the Faculty of Exact and Natural Sciences at the University of Buenos Aires.
