Transcriptome analysis of rice roots and tips in early development by massive parallel sequencing

ABSTRACT: Despite the major physiological dissimilarities between roots and their tips, differences in their gene expression profiles remain largely unexplored. In this research, the transcriptome of rice (Oryza sativa L. subsp. Japonica) mature root tissue and root tips was monitored using mRNA-Seq at 2 time points. Almost 50 million 76 bp reads were mapped onto the rice genome sequence, differential expression patterns between tissues and time points were investigated and at least 1,006 novel transcriptionally active regions (nTARs) were detected to be expressed in rice root tissue. More than 30,000 genes were found to be expressed in rice roots, among which 1,761 root-specific and 306 tip-specific transcripts. Mature root tissue appears to respond more strongly to external stimuli than tips, show
