Normal green leaves contain low levels of ferritin which stores 5 to 10% of the total iron (approximately 350 iron atoms/molecule). Chlorotic leaves do not have measurable amounts of ferritin, whereas iron-loaded leaves contain high levels of well-filled ferritin (1,500 to 2,500 iron atoms/molecule). The role of ferritin during a transient iron surplus in leaves was investigated. It is suggested that a short-term overdose of iron transported into the leaf is largely stored in or near the vessels in such a form that it can be quickly mobilized for export. Iron that reaches the mesophyll cells in an overdose situation is stored in ferritin and, when released, is most likely used for the leaf cells themselves and not for export.
正常的绿叶中含有低水平的铁蛋白，铁蛋白可储存总铁量的 5%至 10%（大约 350 个铁原子/分子）。黄化叶片中没有可测到的铁蛋白，而含铁量高的叶片中则含有大量填充良好的铁蛋白（1500 至 2500 个铁原子/分子）。研究了铁蛋白在叶片中暂时铁过剩期间的作用。有人认为，大量铁进入叶片后，大部分以某种形式储存在导管内或附近，以便迅速动员用于输出。在铁过量的情况下到达叶肉细胞的铁储存在铁蛋白中，当释放时，最有可能被用于叶细胞本身，而不是用于输出。
