Through our BBSRC-funded work on auxin signalling in the model plant arabidopsis we have discovered a way in which plant root systems can be altered to enhance the uptake of water and nutrients. The invention, known as ARF-DCA technology, allows the modulation of specific aspects of development in a manner that retains the plasticity of responses to environmental conditions such as soil nutrient levels. These traits are extremely attractive to breeders and seed companies but in order to take the next step in the commercialisation of the technology we must demonstrate its efficacy in an economically-important crop. Here we describe a work programme of work to translate our proof-of-concept ARF-DCA work in arabidopsis to the globally-important oilseed crop, oilseed rape and further, to broaden the scope of the invention by demonstrating that ARF-DCA technology can also be used to enhance additional auxin-regulated root traits that are crucial to crop nutrition and yield performance.

通过在模型植物拟南芥中，通过BBSRC资助的有关生长素信号传导的工作，我们发现了一种可以改变植物根系以增强水和养分吸收的方式。该发明称为ARF-DCA技术，允许调节开发的特定方面，以保留对环境条件（例如土壤养分水平）的响应的可塑性。这些特征对育种者和种子公司非常有吸引力，但是为了迈出该技术商业化的下一步，我们必须在经济上重要的农作物中证明其功效。在这里，我们描述了一项工作计划，以将我们的概念证明ARF-DCA在拟南芥中的工作转化为全球重要的油料种子，油料种子的强奸和进一步的工作，以扩大该工具的范围，以证明ARF-DCA技术还可以使用还可以增强对作物至关重要的营养和营养成分至关重要的生长素的根特性。
