What is Mode of Action?
A mode of action (MoA) is a term used to describe change at a cellular or molecular level. This transition can be anatomical or functional and always results from exposure to another living organism or any chemical or biological change in the cellular or molecular environment of a living organism.
For example, when referencing mode of action in terms of phosphorus solubilisation, it refers to a change made to the phosphorus at a molecular level that makes this nutrient more soluble and bioavailable for the plant.
Phosphorus is vital for a range of plant stages and features, including the early stages of development, tissue stiffness, root growth, fruit formation, inflorescence (flowering), and also resistance to cold and disease.
Iron is also an essential nutrient, and of the microelements necessary for plants to function properly, iron is chief among them.
