HORTICULTURE

Detailed explanation-1: -Plants (crops, medicinal or ornamental), can be infected by viruses. It all may start with an insect bite. The virus only has to reach a single cell to initiate infection. However, as viruses cannot do anything by themselves, they need to hijack the infected cell’s mechanisms to produce copies of themselves.

Detailed explanation-2: -Plants recognize these elicitors with a help of immune receptors present on the plasma membrane which eventually trigger signaling cascades to activate various DAMP or PAMP-triggered immunity defense mechanisms, these are also known as Defense Triggered Immunity (DTI) or PTI, respectively (Jones and Dangl 2006).
