New crop`s need to emerge to provide sustainable solutions to climate change and increasing abiotic and biotic constraints on agriculture. A large breadth of northern fruit trees and shrubs exhibit a high potential for domestication; however, obstacles to implementing traditional breeding methods have hampered or dissuaded efforts for improvement. This review article proposes a unique roadmap for domestication of northern fruit crops, with a focus on biotechnological (e.g. genome editing, rapid cycle breeding, and transformation) approaches that can boast rapid evolutionary gains. In addition, numerous biotechnological (e.g. virus-induced flowering and grafting-mediated flowering) and breeding strategies (e.g. adaptation of speed breeding to fruit trees) that can hasten the transition from juvenility to sexual maturity are described. A description of an accelerated genetic breeding strategy with insights for 16 underutilized species (e.g. shagbark hickory, running serviceberry, horse chestnut, and black walnut) is provided to support their enhancement. Deemed unrealistic only a decade ago, progress in the realm of bioengineering heralds a future for northern orphan crops through the implementation of fast-tracked crop improvement programs. As such, the roadmap presented in this article paves the way to integrating these novel biotechnological discoveries and propel the development of these forgotten crops in a sustainable and timely manner.
新作物的出现对于为气候变化以及农业中日益增加的非生物和生物胁迫提供可持续解决方案至关重要。大量北方果树和灌木具有很高的驯化潜力;然而,传统育种方法实施过程中的障碍阻碍或打消了改良的努力。这篇综述文章提出了一条北方水果作物驯化的独特路线图,重点关注能够实现快速进化进展的生物技术方法(如基因组编辑、快速循环育种和转化)。此外,还描述了许多能够加速从幼年期向性成熟转变的生物技术(如病毒诱导开花和嫁接介导开花)和育种策略(如果树的快速育种适应性)。提供了一种加速遗传育种策略,并对16种未充分利用的物种(如糙皮山核桃、匐枝花楸、七叶树和黑胡桃)提出了见解,以支持对它们的改良。仅仅在十年前还被认为不切实际的生物工程领域的进展,预示着通过实施快速作物改良计划,北方孤儿作物的未来。因此,本文提出的路线图为整合这些新的生物技术发现铺平了道路,并以可持续和及时的方式推动这些被遗忘作物的发展。
