Exploiting the Arabidopsis genome sequence as a molecular 'toolbox' for Brassica improvement

利用拟南芥基因组序列作为油菜改良的分子“工具箱”。澳大利亚作为油菜(Brassica Napus)主要出口国的地位正受到我们的国际竞争对手在产量和质量方面的遗传改良的威胁。我们将从拟南芥(‘工具箱’)中识别基因，这些基因将用于加快油酸含量、抗病性和早花、耐寒性等农艺性状的新油菜品种的选育速度。拟南芥和油菜籽之间的基因组相似性将被用来将拟南芥的特定基因直接定位到油菜籽中。基于这些知识，我们将开发基因特异的分子标记，用于快速选择澳大利亚适应的油菜籽品种。

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.
