A novel reversible male sterility system for hybrid seed production in canola, cotton and oilseed mustard

对谷物、纤维和其他农产品的需求最近显著增加。因此，粮食生产安全正在成为一个关键的全球问题。我们已经确定了控制绒毡层和花粉发育的中心成分（AtMYB103），并利用AtMYB103设计了一种新的可逆雄性不育系统。该项目为油菜、棉花和芥菜开发的高效杂交种子生产系统将提高澳大利亚油籽和纤维工业的生产力。AtMYB103基因在许多作物中保守。因此，获得的新技术和知识将适用于广泛的作物植物，并对农业和食品工业具有重要意义。

Demand for grains, fibre and other agricultural products has recently increased significantly. Hence, the security of food production is emerging as a critical global issue. We have identified a central component (AtMYB103) controlling tapetum and thus pollen development and designed a novel reversible male sterility system using AtMYB103. The efficient hybrid seed production systems developed in this project for canola, cotton and mustard will increase the productivity of the Australian oilseed and fibre industries. AtMYB103 gene is conserved among many crop plants. Hence, the new technologies and knowledge gained will be applicable to a wide range of crop plants and have important implications for the agricultural and food industries.
