Fig. 3From: Identification and profiling of upland cotton microRNAs at fiber initiation stage under exogenous IAA applicationSequence length distribution of small RNAs from six libraries. Libraries of C_1, C_2, C_3, I_1, I_2, and I_3 were constructed from control and IAA treated ovules at − 3, 0, and 3 DPA. The 24 nt small RNA group is much larger than the othersBack to article page
