frequent increase in (Ca
2+ ) cyt . Herbivore OSs induce (Ca
2+ ) cyt concentration whereas
no change noted in control only with mechanical damage. Herbivore derived
elicitors, inceptin and volicitin, were found to be associated with Ca
2+ influx
which triggers ROS (H 2 O 2 ) (Schmelz et al. 2006). Other responses are Ca
2+ ion
efflux and influx, activation of NADPH oxidase, production of radical molecules
(ROS), synthesis of metabolites like jasmonic acid and ethylyne, change in proteomics of cell, emission of volatile organic compounds for help, and finally expression
of late response gene against herbivore (Miller and Mittler 2006) (Fig. 16.1).
