Fig. 4From: Cross-talk between transcriptome, phytohormone and HD-ZIP gene family analysis illuminates the molecular mechanism underlying fruitlet abscission in sweet cherry (Prunus avium L)The Volcano diagram of differentially expressed genes between CA and CN (a) and DEGs involving in KEGG pathway enrichment analysis in comparison with CA and CN (b). In (a), The x-axis represents the multiple differential expressions; the y axis represents significance. In (b), The x-axis represents the GeneRatio, GeneRatio = Term Candidate Gene Number/Term Gene Number. The Y-axis represents KEGG Pathway. The size of the bubble is proportional to the number of genes in the KEGG Pathway. And the color represents the Q-value of enrichment. The deeper the color, the smaller the Q-valueBack to article page
