Disease Resistance

What Does Disease Resistance Mean?

In gardening, disease resistance refers to strategic techniques that are used to decrease a plant’s susceptibility to diseases. Indeed, disease resistance can protect the plants by triggering an infection-induced response from the plant’s immune system, or by pre-formed chemicals and structures. The outcome of the disease is eventually determined by the interactions between the environmental conditions, pathogen and the plant.


Maximum Yield Explains Disease Resistance

According to scientists, a plant’s immune system is linked to two tiers of receptors: one that senses molecules from the inner cell wall, and a second that senses outside molecules. These receptors activate defenses when the plant is attacked by any type of plant-borne disease, rendering the plant more resistant against certain conditions.

In some cases, the plant can also activate its defenses when it senses DAMP (damage-associated compounds). As a result, some parts of the plant’s cellular walls are released during infections, which can make the plant stronger.

Disease resistance is extremely important in agricultural output and can even help to breed new varieties of the same plant. It can also aid in laying out specific integrated pest management techniques. According to botanists, the resistance genes in plants have been shown to be effective against certain strains, races, pathotypes or biotypes of pest and this can trigger a fresh emergence of new pathotypes and biotypes.
