Genes that regulate female reproductive organ development are of immense value for Australia as tools for seed improvement. Those from our preliminary screen have convinced our industry partners that they can be agents for engineering of apomixis or creation of fertile seed without fertilisation. This will allow the capture of hybrid vigour in wheat and rice, for which commercial hybrid seed production is not currently available. In wheat alone, apomixis presents for Australia an economic value of more than Aus$ ½ billion per annum. Furthermore, controlled apomixis will accelerate breeding programs that will bring drought resistance and minimal fertiliser requiring varieties to the farmer.

调节雌性生殖器官发育的基因作为种子改良的工具对澳大利亚具有巨大的价值。那些来自我们初步筛选的植物已经说服了我们的行业合作伙伴，它们可以成为无融合生殖工程或在没有受精的情况下创造可育种子的代理人。 这将允许捕获小麦和水稻的杂交优势，目前还没有商业杂交种子生产。仅在小麦中，无融合生殖每年为澳大利亚带来超过50亿澳元的经济价值。此外，控制无融合生殖将加速育种计划，这将为农民带来抗旱性和最少的肥料需求品种。
