Brassica genome organisation and evolution: unlocking the potential of using genome-specific repetitive elements for crop improvement. Introgression of chromosome segments from related Brassica species provides an opportunity to develop locally adapted varieties with improved agronomic and quality traits. There is a need to understand Brassica genome organisation and how this information can be used for enhancing the efficiency of cultivar development. Dispersed and tandem repetitive DNA sequences provide valuable information on the organisation and evolution of plant chromosomes. Methods for monitoring chromosome segment transfer across Brassica species will be developed based on detecting and quantifying genome-specific repetitive DNA sequences. Australian Brassica improvement programs could benefit from this research by adopting methods to detect chromosome segment transfer during interspecific hybridisation.

芸苔属基因组组织与进化：释放基因组特异性重复元件用于作物改良的潜力。来自相关芸苔属物种的染色体片段的渐渗提供了开发具有改进的农艺和品质性状的当地适应性品种的机会。有必要了解芸苔属基因组组织，以及如何使用这些信息来提高品种开发的效率。分散和串联重复的DNA序列提供了宝贵的信息，植物染色体的组织和进化。基于检测和定量基因组特异性重复DNA序列，将开发用于监测芸苔属物种间染色体片段转移的方法。澳大利亚芸苔属植物改良计划可以从这项研究中受益，采用方法来检测种间杂交过程中的染色体片段转移。
