| Abstract |
MicroRNA (miRNA)-guided target RNA expression is vital for a wide variety of biological processes in eukaryotes. The integration of miRNAs in diverse biological networks relies upon the confirmation of their RNA targets. Most miRNA targets in Arabidopsis are validated, but those in rice are yet to b .. [more]e characterized. To identify transcriptome-wide small RNA targets in rice, we generated 20-nt small cDNA library and obtained nearly 40 million reads. Sequence analysis yielded 11,552,007 unique reads that can be perfectly mapped to the rice genome. Sequence analysis not only found homologous targets for conserved miRNAs but also many novel targets. Besides miRNA atregts, the rice degradome contained fragments derived from MIRNA precursors. A closer inspection of these fragments revealed a unique pattern distinct from siRNA producing loci. This attribute can serve as one of the ancillary criteria for separating miRNAs from siRNAs in plants.
