Project description:Bursaphelenchus xylophilus (pinewood nematode, PWN) is a causal agent of pine wilt disease and results in economic and environmental losses in pine forests. The establishment of systemic acquired resistance (SAR) provides positive capacities to control PWN. We selected two SAR elicitors, acibenzolar-S-methyl (ASM) and methyl salicylic acid (MeSA), which effectively inhibited disease symptoms on PWN-infected pine trees. To understand dynamic interactions between pine host and PWN under SAR state, we characterized in vivo transcriptomes of pine trees infected by B. xylophilus according to the ASM and MeSA treatment. After distilled water treatment, pine trees infected by B. xylophilus was used as a negative control.
