ABSTRACT
Plants are exposed to attack by pathogens and insect pests. For protection against this stress, plants have evolved defensive strategies to counteract potential invaders. In the present review comparisons are drawn between herbivores-induced plant volatiles as an elicitor of plant defences and two other classes of signalling molecules, C6 green-leaf volatiles and C4 bacterial volatiles, which appear to prime plant defences thereby enhancing the capacity to mobilize cellular defence responses when plants are faced with herbivore/pathogen attacks. Several chemical changes in the soil are associated with plant growth-promoting rhizobacteria wherein particularly, the volatile components, 2,3-butanediol and acetoin are released extensively that trigger the maximum level of growth promotion.
