Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enrichment based on differentially expressed lncRNAs (DElncRNAs) target genes between Tibetan chickens and Daheng broilers. a The top 20 KEGG pathway enrichment annotated by down-regulated target genes in heart embryonic tissue of Tibetan chickens. b The top 20 KEGG pathway enrichment annotated by up-regulated target genes in heart embryonic tissue of Tibetan chickens. The size of the solid circle indicates the number of genes. The change of bubbles from green to red means that the degree of gene function is increased, and the large bubbles indicate that the number of genes is enriched
