γ-Aminobutyric acid (GABA) is a nonproteogenic amino acid with health-promoting functions. Although tomato fruits have a relatively high GABA content compared with other crops, levels must be further increased to effectively confer the health-promoting functions. In this study, we evaluated the potential of the genome-edited tomato as a breeding material for producing high-GABA hybrid tomatoes. Hybrid lines were produced by crossing the genome-edited tomato with a pure line tomato cultivar, “Aichi First”, and were evaluated for GABA accumulation and other fruit traits. The hybrid lines showed high GABA accumulation in the fruits, which was sufficiently high for expecting health-promoting functions and had minimal effects on other fruit traits, suggesting that the high GABA is a dominant trait and that the genome-edited tomato would be useful as a parental line of hybrid cultivars. These results also indicate that genome editing technology is useful for the rapid breeding of high-GABA hybrid tomato cultivars.

高基因组γ-氨基丁酸含量高的基因组编辑番茄（Solanum lycopersicum）在杂交育种中的利用

γ-氨基丁酸（GABA）是一种非蛋白氨基酸，具有促进健康的功能。尽管与其他农作物相比，番茄果实的GABA含量相对较高，但必须进一步提高其含量才能有效赋予健康促进功能。在这项研究中，我们评估了基因组编辑的番茄作为生产高GABA杂交番茄的育种材料的潜力。通过将基因组编辑的番茄与纯品系番茄品种“ Aichi First”杂交来生产杂交品系，并对其GABA积累和其他果实性状进行评估。杂交品系在果实中显示出高的GABA积累量，足够高以达到促进健康的功能，而对其他果实性状的影响却很小，这表明高GABA是显性特征，经基因组编辑的番茄将作为杂交品种的亲本系有用。这些结果还表明，基因组编辑技术可用于高GABA杂交番茄品种的快速育种。
