Review on Genetical, Morphological, Physiological and Molecular Mechanism of Plant to Insect Resistance

Abstract

Plants and insects have been living together for more than 350 million years. In co- evolution, both have evolved strategies to avoid each other’s defense systems. Plants produce specialized morphological structures, genetical, physiological or secondary metabolites, molecular or proteins that have toxic, repellent, and/or anti nutritional effects on the herbivores, to counter the herbivore attack and the insects have also their own weapons. Research on plant-herbivore interactions is one of the most important and multidisciplinary undertakings in plant biology involving various disciplines to describe chemical and ecological processes influencing the outcome of plant - herbivore interactions. Our understanding of how plants communicate with their neighbors, symbionts, pathogens, herbivores, and with their personal “bodyguards”- the natural enemies, both above and below ground, via chemical signals, is still in its infancy. Because of this reviewing of the genetical, morphological, physiological and molecular mechanism of plant to insect resistance are very important in designing crop plants with better protection against the herbivores.
