基因組編輯的番茄在日本上市
【摘要2021.11.15.一.自由】◎陳成良
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.
「高GABA西西里胭脂」是一種特殊的番茄，富含「γ-氨基丁酸」（GABA），據信這種氨基酸可以讓人放鬆，並有助於降低血壓。
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 GABA.
總部在東京的新創企業Sanatech Seed和築波大學的科學家，利用CRISPR/Cas9基因編輯技術，聯合研發出這種名為「高GABA西西里胭脂」的新品種番茄。這種新種番茄的GABA含量是普通番茄的5到6倍。
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.
日本媒體報導，該公司移除了番茄基因組中的一個抑制域，從而使其能夠生成大量GABA。
Unlike genetically modified foods,
genome-edited plant varieties are considered just as safe as varieties improved
using conventional methods because no outside gene is introduced during the
process.
和基因改造食品不同，基因組編輯植物被認為和用傳統方法改良的新品種一樣安全，因為在基因編輯過程中沒有加入外來基因。
