Sicilian Rouge High GABA is a special type of tomato designed to contain high levels of gamma-aminobutyric acid (GABA), an amino acid believed to aid relaxation and help lower blood pressure.
Tokyo-based startup Sanatech Seed Co. teamed up with scientists at the University of Tsukuba to develop a new variety of tomatoes using CRISPR/Cas9 gene-editing technology. Named Sicilian Rouge High GABA, this new type of tomato contains five to six times the normal level of a type of amino acid called gamma-aminobutyric acid, or GABA. According to Japanese media, the company removed an inhibitory domain within the tomato’s genome to enable it to produce these high levels of GABA.
