Abstract: The Melkersson subcategory is a special Serre subcategory. It was proved thata Serre subcategory which is closed under injective hulls is a Melkerssonsubcategory. However, it has been an open question whether the contraryimplication holds. In this paper, we shall show that this question has anegative answer in general.
