Since its introduction to North America, white pine blister rust (WPBR), caused by Cronartium ribicola J.C. Fisch, has resulted in widespread mortality in western white pine (Pinus monticola D. Don, WWP) and other five-needle pines. Therefore, genomic and proteomic approaches to understanding the resistance mechanisms to WPBR and the identification of the resistance (R) genes that determine the genetic resistance will lead to genetic modifications of great economic significance. Here we summarize the genetic and molecular data that have contributed to our understanding of WWP genetic resistance to WPBR and discuss disease resistance mechanisms conferred by R gene from initial fungal recognition to the inducible expression of defense-related genes.
