Exploiting the Arabidopsis genome sequence as a molecular 'toolbox' for Brassica improvement. Australia's position as a major exporter of canola (Brassica napus) is under threat from genetic improvements in yield and quality being made by our international competitors. We will identify genes from Arabidopsis (the 'tool-box') that will be used to increase the speed of selection of new canola varieties with improved oleic acid content, disease resistance, and agronomic traits such as early flowering and cold tolerance. Genome similarity between Arabidopsis and canola will be exploited to map specific genes from Arabidopsis directly into canola. Based on this knowledge, we will develop gene-specific molecular markers for rapid selection of Australian-adapted canola varieties.

利用拟南芥基因组序列作为芸苔属作物改良的分子“工具箱”。澳大利亚作为油菜（Brassica napus）主要出口国的地位受到我们的国际竞争对手在产量和质量方面的基因改良的威胁。我们将从拟南芥（“工具箱”）中鉴定出基因，这些基因将用于提高新油菜品种的选择速度，这些新油菜品种具有改善的油酸含量、抗病性和农艺性状，如早花和耐寒性。拟南芥和油菜基因组的相似性将被用来将拟南芥中的特定基因直接定位到油菜中。基于这些知识，我们将开发基因特异性分子标记，用于快速选择适应澳大利亚的油菜品种。
