Fig. 3From: Small RNA sequencing provides candidate miRNA-target pairs for revealing the mechanism of apomixis in Zanthoxylum bungeanumFunctional enrichment analysis of differentially expressed miRNAs and their target genes at the four Zanthoxylum bungeanum fruit developmental stages. a Principal component analysis of fruits at the four developmental stages. b Venn diagram of differentially expressed miRNAs at the different developmental stages. c Quantitative distribution of mature miRNAs at the different developmental stages. The bottom panel shows the number distribution of miRNAs at different developmental stages, and the connected black dots represent the number of miRNAs shared by different samples. d Gene Ontology (GO) enrichment analysis of the differentially expressed miRNAs target genesBack to article page
