Screening and classification of lncRNAs in chicken BF. a The novel lncRNAs were mainly classified as intergenic lncRNAs, bidirectional lncRNAs, and sense lncRNAs. b CNCI, CPC, and the SwissProt database were used to analyze the coding potential of the novel lncRNAs. RNAs identified by all three analytical tools were chosen as candidate lncRNAs. c The novel lncRNAs were mainly classified as intergenic lncRNAs, sense lncRNAs, bidirectional lncRNAs, and antisense lncRNAs
