This project aims to identify the membrane transporter protein(s) that endows resistance to the herbicide 2,4-D in wild radish (Raphanus raphanistrum). Wild radish is a particular problem in Australia due to its high competitiveness with crops and widespread resistance to other herbicides. 2,4-D resistance is rapidly increasing and threatening crop production in Australia and the United States. The anticipated outcome of the project is to identify strategies to minimise 2,4-D resistance in wild radish by interfering with the specific transporters that confer resistance and by taking advantage of the fitness cost associated with resistance in some populations. It is expected that this will help to improve crop yields and preserve 2,4-D as an effective herbicide.

本项目旨在鉴定野生萝卜（Raphanus raphanistrum）中赋予除草剂2，4-D抗性的膜转运蛋白。野生萝卜在澳大利亚是一个特别的问题，因为它与作物的竞争力很强，而且对其他除草剂普遍存在抗药性。2，4-D抗性正在迅速增加，并威胁到澳大利亚和美国的作物产量。该项目的预期成果是确定战略，以尽量减少2，4-D抗性野萝卜干扰特定的转运，赋予电阻和利用健身成本与电阻在某些人群。预计这将有助于提高作物产量，并保留2，4-D作为有效除草剂。
