We have added MPSS small RNA data to the site, in addition to our MPSS mRNA libraries; the small RNAs are visible through all of our normal visualization and data access tools. The following links provide examples of regions in which small RNAs match to specific genomic features:

	known microRNAs:	miRNA & miRNA* Sequences osa-MIR167a osa-MIR172b
	inverted repeats:	Chr. 7 Chr. 12
	tandem repeats:	Chr. 5 LOC_Os09g11350 Chr. 9
	centromeric region:	Chr. 4 Chr. 8
	transposons:	Retrotransposon MITE DNA transposon
	trans-acting siRNAs:	TAS3a TAS3b TAS3c

Basic Queries

First choose a database for the MPSS mRNA data (only 17 bp data is available for MPSS small RNAs and full length for all other sequences):

Next in the box below, enter specific information to retrieve map or data:

	Protein entry code (e.g. LOC_Os03g63450) Using an old ID? TIGR Version Converter
	BAC clone name (e.g. OSJNBa0015N08)
	Sequence of mRNA MPSS signature (e.g. GATCATATCTCCCATTC)
	Sequence of small RNA signature (e.g. AGAATCTTGATGATGCT)
	Keyword for predicted protein function (e.g. actin)

Query by Chromosome Position

First choose a database for the MPSS mRNA data (only 17 bp data is available for MPSS small RNAs and full length for all other sequences):

Next click on a region of any chromosome for which you would like to retrieve the map. Because of the size of chromosomes, clicking on the diagram below will take you to a second map where you can refine the position.
