[i] ^aRoApx is root apex.

[ii] ^bShApx is shoot apex.

[iii] ^cInfl is inflorescence.

[iv] ^dThe small RNA read count for sequences that matched the rice genome for each tissue and the overall read count (total) are shown.

[v] ^eDistinct small RNA sequence counts are specific for each tissue and the total distinct count is not the sum of the counts from each tissue due to redundancy.

[vi] ^fThe small RNA complexity is the number of distinct sequences as a percentage of the total read count.
