Correlation analyses of lncRNAs and their potential target genes in M. truncatula. Expression models of intronic-lncRNAs (a), antisense-lncRNAs (b) and their potential target genes in leaves and roots of M. truncatula seedlings responsive to cold treatment. Expression models of lincRNAs and their potential upstream target genes (c), downstream genes (d) in leaves and roots of M. truncatula seedlings responding to cold treatment. The expressions were analyzed by RNA-seq (TPM). Antisense-lncRNA: lncRNA overlapping with reference on the opposite strand; intronic-lncRNA: lncRNA falling entirely within a reference intron; lincRNA: intergenic lncRNA; L: leaves; R: roots; up: expression were induced by cold treatment; down: expression were reduced by cold treatment; ND: no detected
