The biochemical and molecular mechanisms of plants: a review on insect herbivory.

Abstract

Biochemical and molecular mechanisms have been essential mechanisms to reduce various insect attacks on plants. The biochemical methods are wide involving direct and indirect defenses. The defensive chemical substances are secreted effectively to the wound caused by the herbivores (insects and phytopathogens) on plants. Plants responded by producing VOCs which draw the natural enemies of the insects and phytopathogens. The progress observed in the cognition of the stimulus in plants and their potential to control the responses is characterized by the modification observed in molecular mechanisms which shifts our attention to the development of the endogenous resistance methods of preserving crops. The main objective of implementing a biotechnological mechanism in crop production is to employ durable and multimechanistic alternatives to insect pests via the stimulus the plant produces upon encountering the insect attack.
