Project description:Investigation of transcriptome dynamics of Japanese cedar (Cryptomeria japonica) in winter (Dec. 22-23, 2011) and summer (July 30-31, 2012). We investigated seasonal and diurnal transcriptome dynamics of Japanese cedar (Cryptomeria japonica) by analyzing shoot samples collected at four-hour interval for two days in winter and summer, respectively. We first collected sequence data of expressed genes from shoots to designed microarray probes. Microarray analysis revealed the significant difference of transcripts between summer and winter, and the diurnal transcriptome dynamic in summer.Statistical analysis indicated that about 7.7 % of unique genes showed diurnal rhythms with more than two-fold of peak-to-trough amplitude in summer.
Project description:Japanese cedar (Cryptomeria japonica) is an allogamous coniferous species that relies on wind-mediated pollen and seed dispersal, and it is one of the most important forestry tree species in Japan. For accelerating breeding, we collected massive SNPs based on ESTs from several organs using NGS, and thus carried out QTL, GWAS and GS based on high-density linkage maps.

Summer samples were collected at four-hour interval for two days (12 time points) from three different cuttings as biological repeats (total 36 samples). Winter samples were collected at 4:00/8:00/12:00/16:00/20:00/24:00 on Dec 22 and 12:00/24:00 on Dec 23 (total eight samples).
Project description:A custom cDNA microarray analysis was designed based on a proprietary cDNA library and EST data to investigate seasonal gene expression in Japanese cedar cambial region.
