Nucleotide bias at each position of identified miRNAs. Y-axis: frequency of A/U/G/C; X-axis: position in miRNAs. Figure S2. Real-time quantitative PCR validation of nine heat-responsive miRNAs in stamen (a) and pistil (b), respectively. Y-axis shows the log2 ratio of miRNAs expression in HS versus CK. SnoU6 was used as the internal control. Each bar represents the mean ± SE of triplicated assays. Figure S3. Distribution of tRNAs, snoRNAs, and snRNAs in stamen and pistil libraries. Y-axis: frequency of each category of small RNAs. Figure S4. qRT-PCR analysis of the expression of SlLAC4 in stamen (a) and pistil (b) under heat-stress treatment. SlUbi3 was used as the internal control. Each bar represents the mean ± SE of triplicated assays. (ZIP 508 kb
