| Abstract: | In this paper, reaction of plant pathogens invasion and principle of DNA micro array are introduced. Application of DNA micro array in the interaction of plant-microbes was generally reported, including identification of potential defense genes, cluster of gene and identification of cis-elements in the region of promoters, and the cross-interaction of different signal pathways. The mechanism of plant defense was interpreted, including expression of R-gene, signal transduction, and defense pathways. The deficiency, resolving ways and the applying advance were showed. |
