Although seed vigor is a complex physiological trait controlled by quantitative trait loci, technological advances in the laboratory are being translated into applications for enhancing seed vigor in crop plants. In this article, we summarize and discuss pioneering work in the genetic modification of seed vigor, especially through the over-expression of protein L-isoaspartyl methyltransferase (PIMT, EC 2.1.1.77) in seeds. The impressive success in improving rice seed vigor through the over-expression of provides a valuable reference for engineering high-vigor seeds for crop production. In recent decades, numerous genes/proteins associated with seed vigor have been identified. It is hoped that such potential candidates may be used in the development of genetically edited crops for a high and stable yield potential in crop production. This possibility is very valuable in the context of a changing climate and increasing world population.
尽管种子活力是一个由数量性状基因座控制的复杂生理性状，但实验室中的技术进步正在转化为提高作物种子活力的应用。在本文中，我们总结并讨论了种子活力基因改造方面的开创性工作，特别是通过在种子中过表达蛋白质L-异天冬氨酸甲基转移酶（PIMT，EC 2.1.1.77）。通过过表达提高水稻种子活力所取得的显著成功为培育用于作物生产的高活力种子提供了有价值的参考。近几十年来，已鉴定出许多与种子活力相关的基因/蛋白质。希望这些潜在的候选基因可用于开发基因编辑作物，以在作物生产中实现高产稳产潜力。在气候变化和世界人口不断增加的背景下，这种可能性非常有价值。
