Fig. 4From: Discovery of cold-resistance genes in Vitis amurensis using bud-based quantitative trait locus mapping and RNA-seqDifferentially expressed genes discovery based on the transcriptome analysis of grape cultivar ‘SY’ and ‘RG’. a Top 20 enriched KEGG pathways related to differentially expressed genes in cultivars ‘SY’and‘RG’. The colored area represents the number of genes involved in each pathway; color intensity refers to the enrichment factor. Rich Factor defines the ratio of differentially expressed genes in the pathway; the higher is the Rich Factor, the higher is the degree of enrichment. b and c Cluster heat map of differentially expressed genes. Red corresponds to highly expressed genes and green to poorly expressed genesBack to article page
