Fig. 4From: Identification and profiling of upland cotton microRNAs at fiber initiation stage under exogenous IAA applicationPearson correlation of miRNA expression levels among six samples. Ovule samples of control and IAA treated at − 3, 0, and 3 DPA were named as C_1, C_2, C_3, I_1, I_2, and I_3. Correlation coefficients closer to a value of 1 indicate greater similarity in the expression patterns of two samplesBack to article page
