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.

基因含量因品种而异。该项目旨在应用新的基因组工具来识别和鉴定重要作物油菜中的固定和可变基因内容，并利用这一点来了解基因组进化以及开发加速油菜育种的工具。该项目团队开发并使用了一种高分辨率的基因分型方法，以证明基因转换，导致减数分裂期间基因组区域非相互交换的短重组事件，在作物基因组中大量存在。该项目旨在开发方法和资源，以阻止油菜的基因转化，并为基于基因转化的作物改良奠定基础。
