Stress-induced and epigenetic-mediated maize transcriptome regulation study by means of transcriptome reannotation and differential expression analysis

摘要: Plant's response and adaptation to abiotic stresses involve sophisticated genetic epigenetic regulatory systems. To obtain a global view of molecular osmotic stresses, including the non-coding portion genome, we conducted total leaf transcriptome analysis on maize plants subjected prolonged drought salt stresses. Stress application both B73 wild type epiregulator mutant rpd1-1/rmr6 allowed dissection component stress response. Coupling RNA-Seq re-assembly annotated thousands new transcripts, together with 13,387 lncRNAs that may play critical roles in regulating gene expression. Differential expression revealed hundreds genes modulated by long-term application, also many transposons specifically induced The amplitude dynamic stress-modulated sets are very different between plants, as result stress-like effect genome regulation caused mutation itself, which activates stress-related even control condition. analyzed extensive set data, improvement identification give revealing insight into mechanism responsible for
