The molecular mechanisms underlying herbicide metabolism in the liverwort Marchantia polymorpha

到2040年，全球能源需求可能增加50%。这一趋势在人口和经济增长强劲的发展中国家最为明显。生物能源必须成为减缓全球气候变化和减少我们对化石燃料依赖的应对措施的一部分。然而，人们对生物能源生产与土地和水资源储备的竞争感到担忧。一种解决方案是在半干旱土地上种植生物能源原料以生产沼气，而半干旱土地对于传统农业来说过于干燥，植物具有高度水分利用效率的景天酸代谢(CAM)形式的光合作用。与普通的C3和C4作物相比，这些植物的用水量要少10倍，才能产生相同数量的生物量。它们的肉质组织中储存了大量加工后剩下的水分，以及植物物质厌氧消化(AD)产生的高营养消化产物，可以用来补充当地的农业。本研究旨在从生化特征上筛选出适合半干旱地区AD的沼气原料(S)。BBSRC的优先领域：生物能源，可持续地提高农业生产、环境和土地利用，与环境变化共存。

Global energy demand is likely to increase by 50% by 2040. This trend is most pronounced in developing countries with strong population and economic growth. Bioenergy must be part of the response to mitigate global climate change and reduce our dependence on fossil fuels. However, there are concerns over bioenergy production competing with land and water reserves. One solution is the growth of bioenergy feedstocks to produce biogas on semi-arid land that is too dry for conventional agriculture, with plants possessing the highly water-use efficient crassulacean acid metabolism (CAM) form of photosynthesis. These plants use 10-fold less water than common C3 and C4 crops for the same amount of biomass produced. The large amount of water stored in their succulent tissues that is leftover after processing as well as the highly nutritious digestate resulting from the anaerobic digestion (AD) of the plant matter can be used to supplement local agriculture. This research aims to biochemically characterise a selection of CAM species and varieties to determine the most promising biogas feedstock candidate(s) for AD in semi-arid lands.BBSRC priority areas: bioenergy, sustainably enhancing agricultural production, environment and land use, living with environmental change.
