| Outline of Final Research Achievements |
Phenological and growth traits of 240 seedlings from segregating population of Abies sachalinensis derived from crossing between high-altitude and low-altitude origins were mapped on 12 linkage groups, which was constructed from about 500 SNP markers and corresponded to the the number of chlomosomes of the species. The QTL analysis significantly revealed five QTLs for four traits. Moreover, the EST library assembled from different tissues detected 223,621 transcripts and 71,707 genes. Based on transcriptome analysis, database for gene catalogue of Abies sachalinensis was established. In addition, gene expression analyses of adaptive genes showed seasonal trends in several candidate genes.
