Plants can be induced locally and systemically to become more resistant to diseases through various biotic or abiotic stresses. The biological inducers include necrotizing pathogens, non- pathogens or root colonizing bacteria. Through at network of signal pathways they induce resistance spectra and marker proteins that are characteristic for the different plant species and activation systems.
Plants diseases or phytopathogens affects plants right from the planting stage up to the harvesting and storage of the produce. Consequently, the plants have evolved several different mechanisms by which they defend themselves. These defense mechanisms in plants are termed as “basal resistance”.
