| Outline of Final Research Achievements |
We generated a draft genome of Fagus crenata (Fagaceae), as a case study of tree in Fagales, with some considerations of the methods about its assembly and gene prediction. A software of Platanus resulted in the highest quality of the genome assemble compared to others, SOAPdenove and ALLPaths-LG, due to the efficient algorithm of De novo assembly to frequent heterozygous genome. This result suggest that F. crenata genome has heterozygous as a long-living plant with self-incompatibility. De novo assembly of RNA-seq. showed non-convergence relationship between RNA-sequence volume (<73 Gb) and predicted gene number, suggesting unavailable method for gene prediction in F. crenata. Gene expression pattern is helpful information for associating the gene annotation in the candidate of the family. Finally, F crenata draft genome (Ver. 3) was generated (523 Mbp with gap) with 96.9% coverage.
