项目摘要

Numerous studies of the effects of CO2 enrichment in the field, including wheat, show that increased crop yields can be obtained through increased photosynthetic carbon assimilation. Furthermore, experiments conducted in the applicant's laboratories on transgenic plants, in which activities of individual enzymes were altered, provided evidence that manipulation of the Calvin cycle has the potential to improve photosynthesis and increase plant productivity. These studies together with integrated systems modelling identified photosynthetic carbon assimilation as an untapped target to increase photosynthetic efficiency and yield by as much as 60%. The overall aim of this project is to exploit the extensive knowledge of photosynthesis and experience gained from its manipulation in model species to produce wheat plants with enhanced photosynthetic performance and increased yield. We will undertake growth, yield, physiological and molecular analysis of transgenic plants in high-light controlled environments, and test the most promising events these in replicated field trials in the UK and in Illinois. Given that our aim is to further increase yields we will be using two modern top yielding cultivars one adapted to W. European temperate conditions and the other to the US Midwest with high humidity and high temperature. Each will be tested in replicated trials in their "native" environments. Use of these two very different growing environments and genetic backgrounds will test the broader efficacy of the transgenic modifications to provide a sound basis for the production of higher yielding varieties for the developing world.

大量关于田间（包括小麦）CO2富集效应的研究表明，可以通过增加光合作用下的碳同化来增加作物产量。此外，在申请人的实验室进行的转基因植物实验中，个别酶的活性被改变，提供了证据，证明操纵卡尔文循环具有改善光合作用和提高植物生产力的潜力。这些研究与综合系统建模一起确定了光合碳同化是一个未开发的目标，可以将光合效率和产量提高多达60%。该项目的总体目标是利用光合作用的广泛知识和从模式物种中获得的经验来生产具有增强光合作用性能和提高产量的小麦植株。我们将在强光控制环境下对转基因植物进行生长、产量、生理和分子分析，并在英国和伊利诺斯州的重复田间试验中测试最有希望的事件。考虑到我们的目标是进一步提高产量，我们将使用两种现代高产品种，一种适应欧洲西部的温带条件，另一种适应美国中西部的高湿度和高温。每个项目都将在各自的“原生”环境中进行重复试验。利用这两种截然不同的生长环境和遗传背景将测试转基因修饰的更广泛功效，从而为发展中国家生产高产品种提供坚实的基础。
