主　　题：Oryza sativa diurnal cycle metabolome time delay rhythmic diversity 

摘      要：Various aspects of the organisms adapt to cyclically changing environmental conditions via transcriptional ***,the role of rhythmicity in altering the global aspects of metabolism is poorly ***,we subjected four rice(Oryza sativa)varieties to a range of metabolic profiles and RNA-seq to investigate the temporal relationships of rhythm between transcription and *** than 40%of the rhythmic genes and a quarter of metabolites conservatively oscillated across four rice *** with the metabolome,the transcriptome was more strongly regulated by rhythm;however,the rhythm of metabolites had an obvious opposite trend between day and *** association analysis,the time delay of rhythmic transmission from the transcript to the metabolite level was~4 h under long-day conditions,although the transmission was nearly synchronous for carbohydrate and nucleotide *** rhythmic accumulation of metabolites maintained highly coordinated temporal relationships in the metabolic network,whereas the correlation of some rhythmic metabolites,such as branched-chain amino acids(BCAAs),was significantly different *** further demonstrated that the cumulative diversity of BCAAs was due to the differential expression of branched-chain aminotransferase 2 at *** research reveals the flexible pattern of rice metabolic rhythm existing with conservation and diversity.
