The process by which the pathogens enter and move within the plant body. Introduction: Pathogens are organisms which infect the plant and cause disease like species of bacteria, fungi , insects and viruses. Plants have a vascular system with a thick cuticle and a layer of epidermis which is impermeable to many pathogens. They also have a defense system of secreting chemicals which prevent the growth of the infection caused by these micro-organisms. Leaf of plants contains stomata pores which help in the movement of water and exchange of gases during photosynthesis and respiration in plants.
