The Journal of Agricultural and Food Chemistry Research Article of the Year Award 2020

The Journal of Agricultural and Food Chemistry (JAFC) and the ACS Divisions of Agrochemicals (AGRO) and Agricultural and Food Chemistry (AGFD) are pleased to announce the winners of the 2020 Journal of Agricultural and Food Chemistry Research Article of the Year Award.  Launched in 2013, this award annually recognizes outstanding research work in the areas of agrochemicals and food chemistry with the support of the ACS Divisions of Agrochemicals and Agricultural and Food Chemistry.

Winner of the AGRO Division Best Research Article:

3-Chloro-5-trifluoromethylpyridine-2-carboxylic acid, a Metabolite of the Fungicide Fluopyram, Causes Growth Disorder in Vitis vinifera

DOI: 10.1021/acs.jafc.8b05567

By: Peter Robatscher, Daniela Eisenstecken, Gerd Innerebner, Christian Roschatt, Barbara Raifer, Hannes Rohregger, Hansjörg Hafner, and Michael Oberhuber


In this research article, the authors identified and proposed a metabolite of the fungicide fluopyram, as the causing agent of phytotoxic damage on grapevines in the spring and summer of 2015 in several countries in Europe.  Through greenhouse and field trials, the metabolite of fluopyram, PCA (3-chloro-5-trifluoromethylpyridine-2-carboxylic acid), was shown to cause leaf epinasty, impaired berry development leading to crop loss, and root-growth anomalies, similar to auxin herbicides in a dose-dependent manner.

Winner of the AGFD Division Best Research Article:

Transglycosylation Forms Novel Glycoside Ethyl α‑Maltoside and Ethyl α‑Isomaltoside in Sake during the Brewing Process by α‑Glucosidase A of Aspergillus oryzae

DOI: 10.1021/acs.jafc.9b06936

By: Yusuke Kojima, Chihiro Honda, Izumi Kobayashi, Ryo Katsuta, Satomi Matsumura, Izumi Wagatsuma, Maya Takehisa, Hitoshi Shindo, Masaru Hosaka, Tomoo Nukada, and Masafumi Tokuoka


In this research article, the authors investigated the contribution of enzymes produced by the fungus Aspergillus oryzae in the saccharification process of brewing Sake, a Japanese rice wine.  The (agdA) gene of Aspergillus oryzae coding for the a-glucosidase A enzyme, was knocked out to identify which components of Sake were produced by AgdA’s enzymatic activity.  The results identified two novel transglycosylation products that were found to be present in many commercially available types of sake as well as in the natural environment.

Congratulations to this year’s award recipients! The awards will be presented at the 2020 ACS Fall National Meeting in San Francisco, CA. Each award consists of an honorarium, a plaque, and travel expenses to attend the ACS National Meeting and present their research work. Each award recipient is invited to give a talk as part of each division’s regular symposium sessions. Research Article of the Year Awards will be accepted by an author representative on behalf of the co-authors of the winning articles.

Accepting The Best Research Article Award (AGRO Division) on behalf of all co-authors: Dr. Peter Robatscher and Dr. Michael Oberhuber

Dr. Peter Robatscher is a chemist and scientist at the Laimburg Research Centre in Pfatten (Vadena), Italy. In 2003, he received a Ph.D. in Chemistry from the University of Innsbruck, Austria, with a thesis on the synthesis of amino acid building blocks. In 2004, he joined Laimburg Research Centre, where he analyzed pesticides and agrochemicals in agricultural products. Since 2011 he is head of the Laboratory for Flavours of Metabolites, located at NOI Techpark in Bolzano, Italy. His group is working in the field of food quality, traceability, and plant health by applying targeted and untargeted metabolomics on food and plant extracts.

Dr. Michael Oberhuber is the director of the Laimburg Research Centre in Pfatten (Vadena), Italy, since 2009. He holds an MSc. and a Ph.D. in chemistry from the University of Innsbruck, Austria. During his Ph.D. thesis, he investigated the molecular processes of autumnal leave senescence, unraveling the secrets of the fall colors.

In 2003, he moved to Skaggs Institute for Chemical Biology at The Scripps Research Institute in San Diego, CA, to study molecular evolution and the origin of life. Back in Europe, he joined Sandoz Development Centre at Sandoz/Novartis (Kundl, Austria) as the laboratory head for the development of pharmaceuticals.

His research interests include agricultural chemistry, nutrition, natural products, and chemical biology aimed to improve the competitiveness and sustainability of local agricultural production.

Accepting The Best Research Article Award (AGFD Division) on behalf of all co-authors: Dr. Masafumi Tokuoka

Dr. Masafumi Tokuoka is an Associate Professor at Tokyo University of Agriculture in Japan. His education includes a Ph.D. in Agriculture from the Department of Bioindustrial Informatics and Genomics, Graduate school of Agricultural Science at Tohoku University.  His Ph. D. thesis theme was heterologous gene expression of Aspergillus oryzae. He is currently an Associate Professor in the Department of Fermentation Science and Technology at Tokyo University of Agriculture. Dr. Masafumi Tokuoka current work is focusing on the elucidation of unique metabolites in traditional Japanese foods and liquors, especially “sake” based on LC-MS analysis and gene engineering of Aspergillus oryzae strain.

The ACS Publications Division would like to thank the Journal of Agricultural and Food Chemistry Associate Editors who nominated articles for the 2020 awards, and to the AGRO and AGFD division member contributions to the winners’ selection committee.  The Journal of Agricultural and Food Chemistry hopes to see many of its readers and authors at the Fall 2020 ACS National Meeting in San Francisco, CA.  Please do join us at the symposia honoring these best research article awards to celebrate their prestigious and exciting achievement.
