Transcriptomic, metabonomic and proteomic analyses reveal that terpenoids and flavonoids are required for Pinus koraiensis early defence against Bursaphelenchus xylophilus infection.

ABSTRACT: Pine wilt disease (PWD), caused by the pine wood nematode (PWN) Bursaphelenchus xylophilus, threatens Pinus seriously. Pinus koraiensis is one of the most important pine species in China and is the host for PWN. However, our understanding of the defence-regulating process following infection by B. xylophilus at the molecular level remains limited. To understand the mechanisms that P. koraiensis responds to B. xylophilus invasion, P. koraiensis was inoculated with B. xylophilus solutions and observed no obvious symptoms during the early stage; symptoms began to appear at 5 dpi. Therefore, we conducted comparative transcriptomic, metabonomic and proteomic analyses between P. koraiensis 5dpi and 0 dpi. In infected plants, 1574 genes were significantly up-regulated, including 17 terpenoid-, 41
