为了满足日益增长的粮食需求，需要大幅度提高产量。小麦尤其如此，近年来全球小麦产量停滞不前。增加光合作用已被确定为实现产量提高的主要目标。为了增加小麦中的叶片光合作用，通过转化和表达二穗短柄草SHBG基因构建体来增加Calvin-Benson循环酶景天庚酮糖-1，7-二磷酸酶（SHBG）的水平。在温室条件下生长具有增加的SBR 4蛋白水平和活性的转基因株系，并且显示增强的叶片光合作用和增加的总生物量和干种子产量。这显示了通过增加小麦等作物物种的叶片光合作用来提高产量潜力的潜力。最后对今后进一步提高小麦光合作用的策略进行了讨论。这篇文章是主题问题“增强作物光合作用：改进目标”的一部分。
To meet the growing demand for food, substantial improvements in yields are needed. This is particularly the case for wheat, where global yield has stagnated in recent years. Increasing photosynthesis has been identified as a primary target to achieve yield improvements. To increase leaf photosynthesis in wheat, the level of the Calvin–Benson cycle enzyme sedoheptulose-1,7-biphosphatase (SBPase) has been increased through transformation and expression of a Brachypodium distachyon SBPase gene construct. Transgenic lines with increased SBPase protein levels and activity were grown under greenhouse conditions and showed enhanced leaf photosynthesis and increased total biomass and dry seed yield. This showed the potential of improving yield potential by increasing leaf photosynthesis in a crop species such as wheat. The results are discussed with regard to future strategies for further improvement of photosynthesis in wheat. This article is part of the themed issue ‘Enhancing photosynthesis in crop plants: targets for improvement’.
