Outline of Final Research Achievements

A more economic and efficient SuperSAGE was established for exhaustive transcriptome analyses of a pile of samples, that is, homopolymer extension by Terminal deoxynucleotidyl transferase was introduced for the double strand cDNA synthesis. Also a dual labeling system was used in the sequencing with a NGS. The exhaustive transcriptome analyses using the modified SuperSAGE revealed that (1) pines attached by pine wood nematode expressed associated genes immediately after the infection, and (2) there are many differences in the gene expression among the resistant clones of Japanese black pine.
