Table 2 Direct mapping of lncRNA transcripts to the genome of another species

Species 1 (in which lncRNAs are captured by RNA-seq libraries)

Species 2 (in which lncRNA can be inferred)

Number of lncRNA models detected within a region of conserved synteny between species 1 and 2, but not captured by the RNA-seq libraries of species 2

Number of lncRNA models from species 1 mapped to the genome of species 2

% of lncRNA models detected by direct genome mapping

Number of intergenic regions in the syntenic blocks conserved between these two species

% of intergenic regions in which a lncRNA from species 1 is inferred in species 2
