Functional analysis of protein coding genes co-expressed with lncRNAs that are differentially-expressed in response to low-nitrogen stress in barley shoots. a GO analysis; b KEGG analysis; c Cytoscape network of differentially-expressed lncRNAs and co-expressed protein coding genes: red triangles represent lncRNAs and green circles represent protein coding genes, with the size and complexity of the network reflecting the number of interactions involved (Additional file 2)
