Psalteriomonas is a genus of amoebae in the group of Heterolobosea.[1]
The genus name is derived from psalterium, which means harp, referring to the novel harp-like structure found in transverse sections through the MTOR (microtubule-organizing ribbon) and the connecting microfibrillar bundle.[2]
Hydrogenosomes of Psalteriomonas lanterna
Electron microscopy of P. lanterna flagellates reveals a large globule in the centre of the cell that is build up from stacks of some 20 individual hydrogenosomes. The individual hydrogenosomes are surrounded by a double membrane that encloses a homogeneous, dark staining matrix lacking cristae. The "modified mitochondria" are found in the cytoplasm of the cell and are surrounded by 1-2 cisterns of rough endoplasmatic reticulum, just as the mitochondria of certain related aerobic Heterolobosea. The ultrastructure of the "modified mitochondria" and hydrogenosomes is very similar, and they have the same size distribution as the hydrogenosomes that form the central stack.[3]
