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.

近期对谷物、纤维等农产品的需求大幅增加。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从而控制花粉发育的核心成分（AtMYB103），并使用 AtMYB103 设计了一种新型可逆雄性不育系统。该项目为油菜籽、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行业的生产力。 AtMYB103 基因在许多农作物中是保守的。因此，所获得的新技术和知识将适用于广泛的农作物，并对农业和食品工业产生重要影响。
