The protein encoded by RBB1 contained two conserve domain ATP-synt-DE-N and AtpC from 3 to 83 and from 1 to 133. All above showed that the full length cDNA RBB1 encoded ATP synthase CF1 epsilon chain protein The plant resistant mechanism is very sophisticated and one of the mainly responses is the metabolic change.

植物的抗病机理非常复杂，其主要反应之一就是代谢上的变化，例如，在利用cDNA微阵列对水稻抗稻瘟病近等基因系的分析中，检测到了很多与光合作用和糖代谢功能有关的差异表达片段；在小麦中也筛选到一个植物中ATP酶具有高度同源性的cDNA序列可能与小麦抗白粉病相关。

In this role, the epsilon takes a 0-ary function/functor.

在这种情况下，空串使用一个零元函数/函数对象。
