The domestication of grasses has historically favored annual species due to their rapid growth and suitability for crop rotation; however, such crops rely heavily on human input. In contrast, perennial grasses, which live for multiple years, offer significant environmental benefits, such as improved soil health and natural resilience to biotic and abiotic stress, but have not yet been domesticated. Gene editing of yield-related genes presents an opportunity to improve yield stability in perennial cereal crops. However, this process typically requires transformation to introduce gene-editing tools, and many perennial grasses are recalcitrant to traditional transformation. Alternative transformation methods have recently emerged, offering simpler, faster, and more genotype-independent approaches. These methods bypass the need for tissue culture and could potentially be used to transform recalcitrant plants more efficiently. In this review, we evaluate the potential of transformation methods for developing perennial cereal crops and advocate for exploring the role of such crops in sustainable agriculture.
由于一年生禾本科植物生长迅速且适合轮作,历史上对其驯化更为青睐;然而,这类作物严重依赖人力投入。相比之下,多年生禾本科植物可存活多年,具有显著的环境效益,如改善土壤健康状况以及对生物和非生物胁迫的自然恢复力,但尚未被驯化。对产量相关基因进行基因编辑为提高多年生谷类作物的产量稳定性提供了契机。然而,这一过程通常需要通过转化来引入基因编辑工具,而许多多年生禾本科植物对传统转化方法具有抗性。最近出现了替代转化方法,提供了更简单、更快且更不依赖基因型的途径。这些方法无需组织培养,有可能更有效地用于转化难转化的植物。在本综述中,我们评估了转化方法在培育多年生谷类作物方面的潜力,并主张探索这类作物在可持续农业中的作用。
