By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Life Science Research are discussed in a new report. According to news reporting out of Yongin, South Korea, by NewsRx editors, research stated, "Coexpression network analysis is useful tool for identification of functional association of coexpressed genes. We developed a coexpression network of rice from heat stress transcriptome data."
Our news journalists obtained a quote from the research from Myongji University, "Global transcriptome of rice leaf tissues was performed by microarray at three time points-post 10 and 60 min heat stress at 42 A degrees C and 30 min recovery at 26 A degrees C following 60 min 42 A degrees C heat stress to investigate specifically the early events in the heat stress and recovery response. The transcriptome profile was significantly modulated within 10 min of heat stress. Strikingly, the number of up-regulated genes was higher than the number of down-regulated genes in 10 min of heat stress. The enrichment of GO terms protein kinase activity/protein serine threonine kinase activity, response to heat and reactive oxygen species in up-regulated genes after 10 min signifies the role of signal transduction events and reactive oxygen species during early heat stress. The enrichment of transcription factor (TF) binding sites for heat shock factors, bZIPs and DREBs coupled with up-regulation of TFs of different families suggests that the heat stress response in rice involves integration of various regulatory networks. The interpretation of microarray data in the context of coexpression network analysis identified several functionally correlated genes consisting of previously documented heat upregulated genes as well as new genes that can be implicated in heat stress."
According to the news editors, the research concluded: "Based on the findings on parallel analysis of growth of seedlings, associated changes in transcripts of selected Hsps, genome-wide microarray profiling and the coexpression network analysis, this study is a step forward in understanding heat response of rice, the world's most important food crop."
