伊丽莎白·萨特利、安妮·奥斯本及其同事在这篇文章中讨论了植物代谢工程中的四个长期挑战:创造能够提供自身氮素的植物,提高营养含量,更好地作为生物燃料发挥作用,并提高光合作用效率。在过去的二十年里,植物代谢工程取得了长足的进步,著名的成功案例包括黄金大米。在这里,我们讨论该领域在解决四个长期挑战方面的进展:创造满足自身氮素需求的植物,从而减少或消除对氮肥的需求;提高农作物的营养含量;通过加入自毁木质素来设计含有易于发酵的糖类的生物燃料原料;以及提高光合作用效率。我们还展望了这一领域新兴研究领域的未来。
Elizabeth Sattely, Anne Osbourn, and colleagues discuss in this Essay four long-standing challenges in plant metabolic engineering: to create plants that provide their own nitrogen, have improved nutrient content, function better as biofuels, and have increased photosynthetic efficiency. Great strides have been made in plant metabolic engineering over the last two decades, with notable success stories including Golden rice. Here, we discuss the field's progress in addressing four long-standing challenges: creating plants that satisfy their own nitrogen requirement, so reducing or eliminating the need for nitrogen fertilizer; enhancing the nutrient content of crop plants; engineering biofuel feed stocks that harbor easy-to-access fermentable saccharides by incorporating self-destructing lignin; and increasing photosynthetic efficiency. We also look to the future at emerging areas of research in this field.
