BMC Genomics

Table 3 Composition of the small RNA library from soybean roots

Type of small RNA	Number of reads	Frequency^a (%)
miRNAs
Conserved miRNAs	3758^b	2.46
Novel miRNAs	793	0.52
(Total)	(4563)	(2.98)
Unidentified RNAs	38815	25.43
Chloroplast RNAs	832	0.55
Other small RNAs (rRNA, tRNA, snoRNA)	102,776	67.33
Fabaceae repeats	5,680	3.72
Total	152,654	100.00

^a Frequency is calculated as the percentage of RNAs in each class divided by the total number of RNAs that matched a known soybean sequence.
^b One conserved miRNA (ppt-miR896) was also identified in the search for other small RNAs
