Phytosiderophores

Phytosiderophores (pronounced: fy-toh-sid-er-o-phores) are a group of naturally occurring compounds secreted by plants, specifically graminaceous plants, to chelate and absorb iron from the soil. The term is derived from the Greek words "phyto" meaning plant, and "siderophore" which means iron carrier.

Etymology

The term "Phytosiderophores" is derived from three Greek words: "phyto" meaning plant, "sidero" meaning iron, and "phore" meaning carrier. Thus, the term literally translates to "plant iron carriers".

Function

Phytosiderophores are primarily involved in the process of iron chelation. They are secreted by the roots of plants into the soil, where they bind to iron(III) ions. This forms a complex that can be absorbed by the plant, allowing it to obtain necessary iron even in iron-deficient soils.

Types

There are several types of phytosiderophores, including mugineic acids and their derivatives. These compounds vary in their structure and iron-binding capabilities.
