When plants work alone, they can only achieve that much. But when plants work side by side with some type of fungus or bacteria, they can go much further! With the aid of both organism, the plants may survive living in the harshest condition possible. Let us dwell into the synergy of plant with both microorganism to learn how do this cooperation happen.

Knowing fungus and bacteria

Fungus and bacteria both are types of microorganism, that is very fine to the naked eye. However, fungus is easier to be seen compared to bacteria. You might remember the mushroom you eat. It is actually the ‘fruit’ of fungus! Some of the time, we need to use microscope to see the actual body of fungus, but normally we can see them as ‘cottony

Nodulation process on roots with mycorrhizae begins with the fungal spores on the soil interacts with chemical released by the root. It later germinated, forms threads of hyphae which later penetrated the root, and from there the fungi establishes network with the plant cell, and forms extensive network of hyphae. Did you know that nutrients in the soil can be classified as mobile and immobile? It is quite different from mobile and immobile nutrients on the plant, where they are divided in different capability to move inside the plant. For immobile nutrient in soil such as phosphorus they are very scarce in the soil, and only available to plants via diffusion. In other words the root itself needs to be literally beside every immobile nutrients in order to be taken by the root. However, this is not possible. Roots of plants can only absorb nutrient in a small range, called as ‘zone of absorption,’ in which the area roots are able to take in available nutrients. Beyond this zone, immobile nutrients are not available to the plants. This is where the beneficial symbiotic relationship in mycorrhizae comes along. Their extensive network of filamentous hyphae extends the zone of absorption of the root, enabling uptake of nutrients to be brought back to the plant, in exchange for the carbohydrate obtained from them.

Bacteria and root nodule

When bacteria forms symbiotic relationship with roots, it also form root
