Abstract

Genome editing technologies are promising for conventional mutagenesis breeding, which takes a long time to remove unnecessary mutations through backcrossing and create new lines because they directly modify the target genes of elite strains. In particular, this technology has advantages for traits caused by the loss of function. Many efforts have been made to utilize this technique to introduce valuable features into crops, including maize, soybeans, and tomatoes. Several genome-edited crops have already been commercialized in the US and Japan. Melons are an important vegetable crop worldwide, produced and used in various areas. Therefore, many breeding efforts have been made to improve its fruit quality, resistance to plant diseases, and stress tolerance. Quantitative trait loci (QTL) analysis was performed, and various genes related to important traits were identified. Recently, several studies have shown that the CRISPR/Cas9 system can be applied to melons, resulting in its possible utilization as a breeding technique. Focusing on two productivity-related traits, disease resistance, and fruit quality, this review introduces the progress in genetics, examples of melon breeding through genome editing, improvements required for breeding applications, and the possibilities of genome editing in melon breeding.

基因组编辑用于甜瓜育种的可能性。
传统的诱变育种需要很长时间才能通过回交去除不必要的突变并培育出新品系,而基因组编辑技术则可以直接修改优良品系的目标基因,因此前景广阔。特别是,这项技术对于功能缺失导致的性状具有优势。人们已做出许多努力,利用这一技术为玉米、大豆和番茄等作物引入有价值的特征。在美国和日本,已经有几种基因组编辑作物实现了商业化。甜瓜是世界上重要的蔬菜作物,在不同地区生产和使用。因此,许多育种工作都致力于提高其果实品质、植物抗病性和抗逆性。对其进行了数量性状位点(QTL)分析,并确定了与重要性状相关的各种基因。最近的一些研究表明,CRISPR/Cas9 系统可应用于甜瓜,从而使其成为一种可能的育种技术。本综述以抗病性和果实品质这两个与生产力相关的性状为重点,介绍了遗传学的进展、通过基因组编辑进行甜瓜育种的实例、育种应用所需的改进以及基因组编辑在甜瓜育种中的可能性。
