Abstract: After pathogen infection, the immune responses of plants depends on signal pathway. In practical application, the common measures of plant inductive resistance technology include cross protection, inoculating rhizosphere microorganisms and exerting elicitors directly. The mechanism of these measures is inducing the accumulation of secondary metabolism substance, such as phytohormone, lignin, callose and phytoalexin. In the future, with the development of genomics, high-throughout screening technique, and large-scale analyzing instrument, this technology will achieve great breakthroughs ceaselessly.

Key words: signal transduction, secondary metabolism substance, cross protection, Rhizosphere microorganisms, elicitors, plant disease control
