Example of collinearity and a positional conservation analysis of a Long non-coding RNA (LncRNA). a Screenshot from GeVo. GeVo calculates the collinearity of a query sequence with the genome of a subject organism. The query here is the nearest protein-coding gene of Ae. arabicum shown in (c), the subjects are Ae. arabicum and A. thaliana. Here there two collinear regions in A. thaliana. The position of the positionally conserved LncRNA is shown with a pink box, while the protein coding genes of A. thaliana and Ae. arabicum are shown with blue boxes. b Screenshot from the PLncDB website, shown are the Arabidopsis thaliana LncRNA (pink) and its nearest protein coding gene (blue). c Screenshot from the CoGe Blast HSP. Pink is the Aethionema arabicum transcript along the Ae. arabicum genome. Blue is the nearest Ae. arabicum protein coding gene.
