length distribution and family classification of small RNAs. a Sequence length distribution of total sRNA in the NN and SL samples. The 24-nt sRNA was the predominant one in each library. b Summary of conservative miRNAs belonged to the known miRNA families in wheat. The two largest numbers of these miRNA families were seven and eight, represented by the families of miR1120 and miR1122, respectively. c The classification of the total sRNAs annotation in NN1 library. d The classification of total sRNAs in NN2 library. e The classification of total sRNAs in SL1 library. f The classification of total sRNAs in SL2 library
