Gene content varies between individual varieties. The project aims to apply novel genomic tools to identify and characterise the fixed and variable gene content in the important crop canola and use this to understand genome evolution as well as develop tools to accelerate canola breeding. The project team have developed and used a high-resolution genotyping approach to demonstrate that gene conversions, short recombination events which lead to the non-reciprocal exchange of genomic regions during meiosis, are abundant in crop genomes. The project aims to develop methods and resources to characterise gene conversion in canola and establish a basis for gene conversion based crop improvement.

基因含量在各个品种之间有所不同。该项目旨在应用新颖的基因组工具来识别和表征重要农作物中的固定基因含量和可变的基因含量，并使用它来了解基因组进化，并开发工具以加速菜籽油。该项目团队已经开发并使用了一种高分辨率的基因分型方法来证明基因转化，在减数分裂过程中导致基因组区域非重新交换的短期重组事件中，作物基因组丰富。该项目旨在开发方法和资源来表征低芥酸菜籽中的基因转化，并为基于基因转化的作物改善建立基础。
