Table 2.

The numbers of nat-siRNAs from the entire regions of cis-NATs, overlap regions of cis-NATs, introns in entire regions of cis-NATs and introns in overlap regions of cis-NATs in Arabidopsis and rice

	Arabidopsis		Rice
Origin of nat-siRNAs	Total	Unique	Total	Unique
Entire NATs	33,826	17,059	162,397	56,209
Introns in entire NATs	14,500	6,988	88,605	29,654
OR of NATs	10,429	6,532	27,852	10,761
Introns in OR of NATs	4,367	2,350	14,207	5,494

Raw reads of siRNAs that perfectly mapped to the Arabidopsis and rice genomes were analyzed here. OR, overlap region.
