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.

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: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.

Project description:Annual transcriptome dynamics of Japanese cedar (Cryptomeria japonica) and effects of photoperiod and temperature on dormancy induction
| PRJNA310189 | ENA
Project description:To investigate the mechanism of annual rhythms in Japanese cedar, annual time series samples were collected from the cuttings planted in natural condition. Also, to investigate the effects of photoperiod and temperature during transition to dormancy, the samples of cuttings grown in the controlled-environmental chamber were analyzed by a microarray.

Project description:<p><em>Cryptomeria fortunei</em> (Chinese cedar) has outstanding medicinal value due to its abundant flavonoid and terpenoid contents. The metabolite contents of <em>C. fortunei</em> needles differ across different seasons. However, the biosynthetic mechanism of these differentially synthesized metabolites (DSMs) is poorly understood. To improve our understanding of this process, we performed integrated non-targeted metabolomic liquid chromatography and gas chromatography mass spectrometry (LC-MS and GC-MS), and transcriptomic analyses of summer and winter needles. In winter, the <em>C. fortunei</em> needle ultrastructure was damaged, and the chlorophyll content and Fv/Fm were significantly (p < 0.05) reduced. Based on GC-MS and LC-MS, we obtained 106 and 413 DSMs, respectively; based on transcriptome analysis, we obtained a total of 41.17 Gb of clean data and assembled 33,063 unigenes, including 14,057 differentially expressed unigenes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses showed that these DSMs/DEGs were significantly (p < 0.05) enriched in many biosynthesis pathways, such as terpenoids, photosynthates, and flavonoids. Integrated transcriptomic and metabonomic analyses showed that seasonal changes have the greatest impact on photosynthesis pathways, followed by terpenoid and flavonoid biosynthesis pathways. In summer Chinese cedar (SCC) needles, DXS, DXR, and ispH in the 2-methyl-pentaerythritol 4-phosphate (MEP) pathway and GGPS were highly expressed and promoted the accumulation of terpenoids, especially diterpenoids. In winter Chinese cedar (WCC) needles, 9 genes (HCT, CHS, CHI, F3H, F3'H, F3'5'H, FLS, DFR, and LAR) involved in flavonoid biosynthesis were highly expressed and promoted flavonoid accumulation. This study broadens our understanding of the metabolic and transcriptomic changes in <em>C. fortunei</em> needles caused by seasonal changes and provides a reference regarding the adaptive mechanisms of <em>C. fortunei</em> and the extraction of its metabolites.</p>
