Abstract

Ensuring an adequate food supply and enough energy to sustainably support future global populations will require enhanced productivity from plants. Oilseeds can help address these needs; but the fatty acid composition of seed oils is not always optimal, and higher yields are required to meet growing demands. Quantitative approaches including metabolic flux analysis can provide insights on unexpected metabolism (i.e., when metabolism is different than in a textbook) and can be used to guide engineering efforts; however, as metabolism is context-specific, it changes with tissue type, local environment, and development. This review describes recent insights from metabolic flux analysis in oilseeds and indicates engineering opportunities based on emerging topics and developing technologies that will aid quantitative understanding of metabolism and enable efforts to produce more oil. We also suggest that investigating the key regulators of fatty acid biosynthesis, such as transcription factors, and exploring metabolic signals like phytohormones in greater depth through flux analysis, could open new pathways for advancing genetic engineering and breeding strategies to enhance oil crop production.

通过代谢通量分析提高种子含油量
要确保充足的粮食供应和足够的能源,以可持续的方式支持未来的全球人口,就必须提高植物的生产力。油籽有助于满足这些需求;但籽油的脂肪酸组成并不总是最佳的,需要更高的产量才能满足日益增长的需求。包括代谢通量分析在内的定量方法可为意外代谢(即新陈代谢与教科书中的不同)提供见解,并可用于指导工程工作;然而,由于新陈代谢具有特定的背景,它会随着组织类型、当地环境和发育而变化。本综述介绍了从油菜籽代谢通量分析中获得的最新见解,并指出了基于新兴课题和发展中技术的工程机会,这将有助于对代谢的定量理解,并有助于生产更多的油。我们还建议,研究脂肪酸生物合成的关键调控因子(如转录因子),以及通过通量分析更深入地探索代谢信号(如植物激素),可以为推进基因工程和育种策略开辟新的途径,从而提高油料作物的产量。
