The importance of cassava as the fourth largest source of calories in the world requires that contributions of biotechnology to improving this crop, advances and current challenges, be periodically reviewed. Plant biotechnology offers a wide range of opportunities that can help cassava become a better crop for a constantly changing world. We therefore review the state of knowledge on the current use of biotechnology applied to cassava cultivars and its implications for breeding the crop into the future. The history of the development of the first transgenic cassava plant serves as the basis to explore molecular aspects of somatic embryogenesis and friable embryogenic callus production. We analyze complex plant-pathogen interactions to profit from such knowledge to help cassava fight bacterial diseases and look at candidate genes possibly involved in resistance to viruses and whiteflies-the two most important traits of cassava. The review also covers the analyses of main achievements in transgenic-mediated nutritional improvement and mass production of healthy plants by tissue culture and synthetic seeds. Finally, the perspectives of using genome editing and the challenges associated to climate change for further improving the crop are discussed. During the last 30 yr, great advances have been made in cassava using biotechnology, but they need to scale out of the proof of concept to the fields of cassava growers.

利用生物技术改善木薯的潜力:综述。

木薯作为世界上第四大卡路里来源,其重要性要求定期审查生物技术对改善作物收成,进步和当前挑战的贡献。植物生物技术提供了广泛的机会,可以帮助木薯成为不断变化的世界中更好的作物。因此,我们回顾了有关木薯品种目前使用生物技术的知识状况及其对未来作物育种的影响。第一个转基因木薯植物的发展历史,为探索体细胞胚发生和易碎的胚性愈伤组织生产的分子方面提供了基础。我们分析复杂的植物-病原体相互作用以从此类知识中获利,以帮助木薯抗击细菌性疾病,并研究可能与木薯的两个最重要特征有关的病毒和粉虱抗性候选基因。该综述还涵盖了通过组织培养和合成种子在转基因介导的营养改良和健康植物的大规模生产中取得的主要成就的分析。最后,讨论了使用基因组编辑的观点以及与气候变化有关的挑战,以进一步改善作物。在过去的30年中,利用生物技术在木薯方面取得了长足的进步,但它们需要从概念验证的范围扩展到木薯种植者的领域。该综述还涵盖了通过组织培养和合成种子在转基因介导的营养改良和健康植物的大规模生产中取得的主要成就的分析。最后,讨论了使用基因组编辑的观点以及与气候变化有关的挑战,以进一步改善作物。在过去的30年中,利用生物技术在木薯方面取得了长足的进步,但它们需要从概念验证的范围扩展到木薯种植者的领域。该综述还涵盖了通过组织培养和合成种子在转基因介导的营养改良和健康植物的大规模生产中取得的主要成就的分析。最后,讨论了使用基因组编辑的观点以及与气候变化有关的挑战,以进一步改善作物。在过去的30年中,利用生物技术在木薯方面取得了长足的进步,但它们需要从概念验证的范围扩展到木薯种植者的领域。
