ABSTRACT
Graphilbum species are important blue stain fungi associated with pine trees and are widely distributed throughout Asia, Australia, and North Africa. Pine wood nematode (PWN) primarily feed on ophiostomatoid fungi such as Graphilbum sp. in wood, the population of PWNs was increased, and incomplete organelle structures were observed in Graphilbum sp. hyphal cells following exposure to PWNs. In this study, we showed that Rho and Ras were involved in the MAPK pathway, SNARE binding and small GTPase-mediated signal transduction, and their expression was upregulated in the treatment group. However, the expression of the Rab7 involved in MAPK and small GTPase-mediated signal pathway was downregulated in the treatment group. Thus, further research is needed to study the MAPK pathway and related Ras and Rho genes in Graphilbum sp. associated with the PWN population. Overall, transcriptomic analysis clarified the basic mechanisms of mycelial growth in Graphilbum sp. fungus used as a food source by PWNs.
