“…The presence of polyphosphates in the blue-green algae Phormidium and Oscillatoria was reported by Keck and Stich (1957) and Ebel et al (1958). During the studies on the phosphorus metabolism of the nitrogen fixing blue green alga Anabaena cylindrica, the author (Talpasayi 1960) observed that radioactive phosphate was readily incorporated into cold trichloroacetic acid soluble polyphosphates.…”

“…The presence of volutin granules or polyP bodies in nonvascular plants is widespread and has been documented in several unicellular and macroalgae as well as in mosses such as Leptobryum and Polytrichum (Keck and Stich 1957). It is well known that the main component of these structures is polyP.…”

Polyphosphate (polyP) has been abundant on Earth long before life began. In living organisms, polyphosphate can be stored in electron-dense granules that have long been referred to as volutin granules. After having being ignored for a long time, this polymer has proven to have numerous unsuspected functions in living organisms and is receiving more attention. The ubiquitous presence of polyP in nature and its structural and physico-chemical characteristics appear to be the drivers for the evolutionary selection of this versatile molecule as a component of cellular processes. Most of our knowledge about the functions of polyP comes from the microbial world. PolyP can influence the transcription and translation of specific genes, act as a metabolic regulator, provide an alternative source of energy, and modulate several stress responses. In plant systems, although the presence of polyP has long been known, its roles in cellular processes have begun to emerge only recently. The purpose of this mini-review is to provide a brief overview of the proposed biological roles of polyphosphates in plants and their roles in microbial/plant interactions.

“…Polyphosphate bodies have been reported in a wide variety of lower plants and animals at the light microscope level ( Keck and Stich 1957, Ebel et al 1958, Tal pasayi 1963. Only a few reports of their presence have been made at the electron microscope level (Harold 1966, Jensen 1968, Fisher 1971, Stewart and Alexan der 1971).…”
