Research Abstract

Resistance mechanisms of pine wilt-resistant pines were investigated from gene expression, histological and biochemical aspects. Expression of defensive genes including PR proteins genes was faster in susceptible clone of Japanese black pine, while reactive oxygen ? lignification related genes were expressed faster in the resistant clone. Destruction of host tissue was severe in susceptible pines, and lignification was conspicuous in resistant pines. Accumulation of antimicrobial substances was not observed in both susceptible and resistant pines except eastern white pine.
